If you are a product designer, procurement buyer, factory engineer, decoration contractor or foreign trade supplier, you must have faced a confusing question: should I pick polycarbonate (PC) sheet or acrylic (PMMA) sheet for my new project?

These two transparent plastic panels are the most popular clear substitutes for glass across all industries, including new energy EV charging equipment, industrial machinery, store display cabinets, building skylights, indoor partitions, electrical insulation parts and home decoration. On the surface, they both look clear, lightweight and easy to process, but once you dig into their real working performance, service life, safety and processing limits, the gap between them is huge.

Many buyers make costly mistakes by choosing the cheaper option blindly without understanding core differences, only to face cracking, yellowing, scratch fogging, fire risks or delivery delays after mass production. This complete comparison guide will break down every single performance dimension between PC sheet and acrylic sheet in plain, easy-to-understand language, no complicated professional jargon. We will cover impact resistance, surface scratch hardness, outdoor UV weather resistance, temperature tolerance, electrical insulation ability, flame retardant safety, bending & CNC processing performance, chemical resistance, weight, light transmittance, cost price, installation maintenance and hundreds of real application cases.

At the end of this article, we will fully introduce our factory’s one-stop custom processing service for both polycarbonate and acrylic sheets, supported by our complete 2026 upgraded workshop equipment, to help you get fully finished custom parts without coordinating multiple suppliers.

1. Basic Definition & Raw Material Core Characteristics Overview

1.1 What is Polycarbonate (PC) Sheet

Polycarbonate sheet (short name PC sheet, also called endurance board) is an amorphous thermoplastic engineering plastic produced from polycarbonate resin through co-extrusion molding. The biggest built-in feature of raw PC material is ultra-high molecular toughness, which makes it extremely resistant to collision and impact. We can produce standard clear PC sheet, double-sided UV weather-resistant PC sheet, hard-coated anti-scratch PC sheet, flame-retardant V0/V2 grade PC sheet, thin insulation PC film and thick solid security PC board, with thickness ranging from 0.125mm up to 18mm.

1.2 What is Acrylic (PMMA) Sheet

Acrylic sheet, chemical name PMMA (polymethyl methacrylate), belongs to transparent general plastic, manufactured via casting or extrusion process. Its core advantage lies in superior surface smoothness, ultra-high light transmittance and natural pencil hardness without extra coating. However, its molecular structure lacks toughness, so the material is inherently brittle and prone to cracking under strong impact or bending force. Common acrylic products include cast acrylic sheet, extruded acrylic sheet, colored frosted acrylic, anti-glare acrylic, with thickness from 1 mm to 30 mm for decorative and display use.

1.3 Quick Core Pros & Cons Preview

❌ Poor heat resistance, permanent deformation occurs above 70℃ continuous temperature

❌ Cannot perform cold bending; only small-radius hot bending allowed, easy to crack during forming

❌ Outdoor service life only 1–2 years, obvious yellowing and brittleness after sun exposure

❌ Poor arc resistance, not suitable for high-temperature electrical insulation components

2. Key Performance Dimension Full Side-by-Side Comparison

2.1 Impact Resistance (The Most Obvious Performance Gap Between PC and Acrylic)

Impact resistance is the dividing line that separates the two materials for safety-related projects, and this gap cannot be eliminated by any surface coating or modification process.

Test Standard & Real Data

We follow ASTM D256 Izod impact test standard for uniform comparison:

• Polycarbonate (PC) sheet: Izod impact strength 80–90 kJ/m²
• Cast acrylic (PMMA) sheet: Izod impact strength only 1.2–2 kJ/m²

Translate the numbers into real daily scenarios:

1. Drop a 3kg metal weight from 2 meters height:
   1. PC sheet: Only slight indentation on surface, no crack, no penetration
   1. Acrylic sheet: Completely shattered into dozens of sharp fragments
2. Hail storm impact test (10mm ice ball falling at 80km/h wind speed):
   1. Double-sided UV weather-resistant PC board: No surface damage at all
   1. Standard acrylic sheet: Full penetration crack, broken into pieces
3. Daily accidental collision (shopping cart, metal tool, passenger bump in public areas):
   1. PC safety guard/shelter panel: No damage, can bear repeated light collision
   1. Acrylic display window/partition: One hard hit creates permanent through crack

Application Selection Rule Based on Impact Demand

اختر PC sheet unconditionally if your project meets any below condition:

• Outdoor public facilities: bus shelters, EV charging station panels, parking carport roofing
• Safety protection equipment: machine transparent guards, anti-hail greenhouse panels, children playground isolation barriers
• Transportation-related parts: train interior partitions, automotive instrument panels, battery insulation shields
• Any location with frequent accidental collision risk, vandalism risk or hail exposure

Choose acrylic sheet only when there is zero impact risk, purely indoor static decoration with no heavy object contact: high-end jewelry display cabinets, indoor decorative wall panels, photo frame backboards, light box diffusers placed inside shopping malls without passenger collision.

2.2 Surface Hardness & Anti-Scratch Wear Resistance

Many clients confuse scratch performance between PC and acrylic, and the key split point is whether the material requires extra hard coating treatment.

Raw Uncoated Material Hardness Data

• Raw unprocessed PC sheet: Pencil hardness 2B, extremely soft. Wiping with cloth mixed with tiny sand grains will leave permanent matte scratch lines, after months of repeated cleaning the whole panel turns foggy and loses transparency completely.
• Standard cast acrylic sheet: Natural pencil hardness H ~ 2H. Daily wiping with microfiber cloth, light metal friction will not leave visible scratches, no fogging problem under regular indoor cleaning cycles.

Hard Coated Upgraded Versions Comparison

We produce hard-coated PC sheet with 3H–5H silicone hard coating to fix the soft surface defect of raw PC: after coating, PC’s scratch resistance surpasses ordinary acrylic, suitable for high-touch public equipment like charging pile touch screens. Acrylic can also receive extra hard coating treatment, but the cost increase is much higher than hard-coated PC, and its base material brittleness cannot be improved by coating.

Practical Maintenance Difference

• Indoor long-term cleaning: Uncoated acrylic wins, no need to worry about minor scratch during daily wiping; uncoated PC will quickly lose transparency after frequent cleaning without hard coat.
• High-frequency public touch scenarios (shared charging equipment, self-service checkout machine): Hard-coated PC is the only reliable choice, as acrylic will crack under accidental heavy impact even if scratch resistant.

2.3 Outdoor UV Weather Resistance & Anti-Yellowing Service Life

This section directly decides which material fits outdoor exposed projects, and this is a critical mistake area for many new buyers.

Aging Test Result (QUV ultraviolet accelerated aging test, 2000 hours equivalent to 5–8 years natural sunlight)

1. Double-sided co-extrusion UV-protected PC sheet: Yellowing index ΔE < 5, slight gloss drop, no brittleness, impact strength retains over 80% of original value. Factory warranty can reach 10–15 years outdoor service life.
2. Standard extruded acrylic sheet: Yellowing index ΔE > 18 after 2000h UV test, obvious amber discoloration, material becomes brittle, impact strength drops below 30%, easy to crack under slight wind vibration. General acrylic only lasts 1–2 years outdoors before severe aging.
3. Single-sided UV PC sheet: If uncoated side faces sunlight, rapid yellowing occurs within 2–3 years, not recommended for full outdoor exposure.
4. Frosted colored acrylic: Color fading happens rapidly under UV radiation, color saturation drops by more than half within one year outdoors.

Climate Adaptation Breakdown

• Tropical coastal areas (strong sunlight + salt spray): Only double-sided UV PC sheet works, acrylic will yellow and crack within 12 months.
• Temperate zone four-season outdoor shelters: UV PC stable for over 10 years; acrylic turns foggy and fragile after 2 summer-winter cycles.
• Indoor window display with direct sunlight: If you hope the panel stays clear for more than 5 years, choose single-sided UV PC sheet instead of acrylic. Acrylic facing window sunlight will turn yellow within 3 years.

2.4 Temperature Tolerance & Thermal Deformation Performance

The maximum sustainable working temperature limits the application in heat-generating equipment such as electrical cabinets, battery equipment and lighting housings.

Continuous & Short-Term Temperature Resistance Data

• Polycarbonate (PC) sheet: Long-term stable use temperature -40℃ ~ +120℃, short-term instant peak temperature up to 135℃, no permanent deformation, no sharp drop of insulation performance under high heat.
• Acrylic (PMMA) sheet: Safe continuous working temperature only 0℃ ~ +70℃. Once environment temperature exceeds 75℃, the panel will warp, bend and produce permanent thermal deformation, even separate from fixed installation frames. Below -10℃, acrylic’s brittleness increases sharply, slight collision leads to cracking.

Typical Scenario Temperature Selection Guide

• High heat equipment surroundings: inverter insulation baffles, power supply box transparent windows, EV battery covers, automotive interior parts — only PC sheet qualifies, acrylic will deform rapidly under long-term heat radiation.
• Low temperature cold northern outdoor environment in winter: UV PC sheet remains tough at -40℃; acrylic becomes fragile and easy to crack under low temperature impact.
• Indoor room temperature decoration environment (20–40℃): Both materials work normally, no thermal deformation risk for acrylic.

2.5 Electrical Insulation, Dielectric Strength & Arc Resistance

For electrical, new energy battery, charging pile and high-voltage test equipment projects, insulation performance is non-negotiable safety standard.

Core Electrical Parameter Comparison

1. Volume Resistivity (internal insulation ability):
   1. PC sheet: >10¹⁶ Ω·cm, stable above 10¹⁵ Ω·cm even under 85℃ / 85%RH high humidity condition
   1. Acrylic sheet: 10¹⁴ ~ 10¹⁵ Ω·cm, insulation resistance drops obviously in humid environment, easy to produce surface leakage current
2. Dielectric Breakdown Strength (high voltage resistance):
   1. PC sheet: 30–40 kV/mm
   1. Acrylic sheet: 15–20 kV/mm, only half of PC’s high voltage resistance limit
3. Arc Resistance (anti-electric arc burning):
   1. PC sheet: 120 seconds anti-arc time, enough time for safety circuit breaker to cut power during short circuit spark
   1. Acrylic sheet: Only 60–80 seconds anti-arc performance, easy to burn through and form conductive carbon track under continuous electric arc, raising fire hazard

Electrical Material Selection Standard

All electrical insulation parts, battery separator plates, charging pile internal baffles, high voltage test equipment shields must adopt UL94 V0 flame retardant PC sheet, acrylic cannot meet long-term high-voltage and high-temperature insulation safety standards. Acrylic is only allowed for low-voltage static light box decorative covers with no live parts behind the panel.

2.6 Flame Retardant & Fire Safety Performance

Fire safety is essential for public buildings, new energy equipment and indoor commercial decoration.

Flame Test Grade Data

• Polycarbonate (PC) sheet: Customizable UL94 V0 highest flame retardant grade. When ignited, it self-extinguishes within 10 seconds, no flaming molten drops that spread fire, releases low-toxic thin smoke, reaches construction B1 fire resistance standard.
• Standard acrylic sheet: UL94 HB flammable grade, continues burning after removing fire source, produces dripping molten flame droplets that ignite surrounding flammable materials, thick black toxic smoke released during combustion, cannot pass B1 building fire test.

Fire Risk Scene Division

• High fire risk projects: EV battery modules, charging station housings, electrical control cabinets, school public shelter facilities, shopping mall ceiling light panels — must select V0 flame retardant PC sheet, acrylic is forbidden for these scenarios.
• Low fire risk static indoor decoration: Closed jewelry cabinets, photo frames, indoor small light boxes with independent fire isolation, acrylic can be used with fire prevention separation measures.

2.7 Bending, Thermoforming & CNC Custom Processing Capacity

Processing feasibility directly affects your custom parts production difficulty and cost, especially if you need curved, arched or special-shaped components.

Cold Bending Ability (Biggest Processing Difference)

• Polycarbonate (PC) sheet: Supports room temperature cold bending without heating. As long as bending radius ≥ 1.5 × sheet thickness, the panel will not crack, no coating peeling for hard coated PC after standard cold bending. We have 5 dedicated cold bending machines in our workshop for mass curved PC part production, such as curved charging gun protective covers, arched carport panels, curved instrument shields.
• Acrylic (PMMA) sheet: Cold bending is completely impossible. Any room temperature bending will create deep surface cracks and through fractures. Only small-radius hot bending after heating oven softening is allowed, complex large arc shapes cannot be realized, production cycle longer and reject rate higher than PC bending processing.

Hot Forming & Thermoforming

PC sheet has wider thermoforming temperature window, less prone to uneven thickness after molding, suitable for deep-drawn 3D protective housings with our 2 vacuum thermoforming machines. Acrylic hot forming requires precise temperature control, easy to produce thin weak areas on curved corners, high scrap rate for complex 3D parts.

CNC Laser Cutting, Drilling & Engraving

Both materials support CNC engraving, laser cutting, hole punching and edge polishing, our 6 CNC routers and 5 laser cutting machines can process both raw materials accurately within ±0.1mm tolerance.

• Acrylic advantage after cutting: Edges can be polished to mirror transparent gloss easily with simple flame polishing process, widely used for decorative display signs.
• PC advantage after cutting: No edge yellowing during laser cutting, polished edges stay clear without discoloration, better toughness for thin insulating sheets with dense small holes.

2.8 Light Transmittance & Optical Clarity

If your project focuses on display, lighting and visual observation requirements, light transmission index is a key reference.

• Cast acrylic sheet: Light transmittance 92–93%, the highest among all transparent plastic panels, ultra-low light scattering, no slight haze, perfect for high-end product display cabinets and high-grade light boxes.
• Standard clear PC sheet: Light transmittance 88–90%, tiny natural micro light scattering exists inside resin, slightly softer light penetration effect than acrylic, will not produce harsh glare under strong backlight.
• Frosted/diffused versions: Both PC and acrylic have matte light diffusion grades, acrylic diffuser has more uniform light mixing effect for indoor ceiling lamps; diffused PC sheet performs better for outdoor lighting boxes with UV exposure.

2.9 Chemical & Solvent Resistance

Different cleaning agents, disinfectants and industrial chemicals will corrode the two materials differently.

Polycarbonate (PC) Sheet Chemical Resistance Performance

• Resistant to: Neutral soapy water, alcohol, isopropanol, dilute weak acid and weak alkali disinfectants (common hospital, public station sanitizers)
• Corroded by: Acetone, strong dichloromethane solvent, concentrated strong acid / strong alkali — contact causes surface whitening, fogging and micro-crack (stress cracking)

Hard-coated PC greatly improves solvent resistance, the coating layer isolates most weak corrosive cleaning liquids, widely used in frequently disinfected public charging equipment.

Acrylic (PMMA) Sheet Chemical Resistance Performance

• Resistant to: Neutral water-based cleaning liquid, low-concentration alcohol
• Corroded by: Alcohol with long-time soaking, all ketone/ester organic solvents, even common disinfectant spray will leave permanent foggy marks on acrylic surface after repeated wiping. Acrylic cannot be used in medical disinfection intensive environments.

2.10 Raw Material Cost & Long-Term Full Lifecycle Expense

Many buyers only compare raw sheet unit price and ignore post-production maintenance & replacement cost, causing higher total expense over years of use.

Short-Term Raw Material Price (Flat Indoor Thin Sheet, No Special Coating)

1mm plain uncoated flat acrylic sheet has lower per square meter cost than standard clear PC sheet, so simple indoor static decoration projects with zero wear risk can save initial material budget by choosing acrylic.

Long-Term Full Lifecycle Cost Calculation (Outdoor Public Project Example)

• Double-sided UV hard-coated PC sheet: Initial purchase cost higher, outdoor service life 10–15 years, almost no replacement or maintenance expense within 10 years, low annual average cost.
• Standard acrylic sheet: Cheaper initial cost, must fully replace after 1–2 years outdoor use, continuous repeated procurement, labor cost for disassembly and reinstallation accumulates rapidly, total expenditure over 10 years is 5–8 times higher than PC sheet.

Mass Custom Processing Cost Difference

Curved bent parts, thick security panels, electrical flame retardant parts: PC overall processing cost is lower, low reject rate during bending and forming; acrylic curved processing has high scrap rate, pushing up total finished product price.

3. Complete Classification of Suitable Application Scenarios

3.3 Dual Material Optional Neutral Scenarios (Select Based On Budget & Service Life Demand)

Indoor machine equipment covers with zero collision risk, small indoor household appliance transparent panels, closed indoor light boxes without UV sunlight exposure:

• If you pursue ultra-clear optical effect, low daily scratch risk and low initial cost: choose acrylic
• If you hope to extend service life over 8 years, have occasional accidental collision risk, or need to reserve possibility of curved modification later: choose UV-protected PC sheet

4. Common Wrong Material Selection Mistakes & Loss Analysis

Mistake 1: Using acrylic sheet for outdoor shelter and charging pile projects

Loss: Yellowing, brittleness and cracking within 1–2 years, full batch replacement required, huge repeated procurement and installation labor cost, negative customer feedback for product quality.

Fix: All outdoor exposed structural transparent panels must adopt double-sided UV co-extrusion PC sheet.

Mistake 2: Applying uncoated raw PC sheet for high-touch indoor self-service equipment

Loss: Permanent scratches after 3–6 months of customer wiping, whole panel foggy, poor product appearance, increased after-sales replacement rate.

Fix: High-frequency touch surface requires 3H–5H hard-coated PC sheet instead of bare PC or acrylic.

Mistake 3: Choosing acrylic for battery, electrical cabinet and high-temperature equipment parts

Loss: Thermal deformation under working heat, poor insulation performance leads to hidden electric leakage fire risk, fails international electrical safety certification.

Fix: All heat-generating electrical components use UL94 V0 flame-retardant PC sheet.

Mistake 4: Trying cold bending acrylic sheet to save material cost

Loss: Mass cracking during forming processing, high scrap rate over 40%, processing cost far exceeds initial raw material price saving, delivery date delayed.

Fix: Any curved parts select cold bendable polycarbonate PC sheet.

Mistake 5: Prioritizing cheap acrylic for public school, playground safety barriers

Loss: One accidental student collision shatters acrylic into sharp fragments, causing safety injury accidents and liability compensation.

Fix: All public safety isolation barriers must use impact-resistant PC sheet.
