When choosing engineering plastic sheets for machinery guards, equipment enclosures, structural parts and display products, PC (Polycarbonate) and ABS(Acrylonitrile Butadiene Styrene) are the two most widely used materials. Many customers confuse PC and ABS because they both have good rigidity and processability, but their performance, appearance and applicable scenarios are very different.
This article clearly compares PC sheet and ABS sheet from all aspects, helping you select the most cost-effective and suitable material.
What Is Polycarbonate (PC)?
Polycarbonate is a high-performance engineering plastic known for:
- excellent impact resistance
- high transparency
- good heat resistance
- strong dimensional stability
It is commonly used for:
- machine guards
- safety shields
- transparent covers
- industrial panels
What Is ABS Plastic?
ABS is a cost-effective thermoplastic known for:
- good strength
- easy machining
- lightweight
- good surface finish
It is widely used in:
- electronic housings
- automotive parts
- plastic enclosures
- consumer products
Key Differences Between Polycarbonate and ABS
| Comparison Item | Polycarbonate Sheet | ABS Sheet |
| Transparency & Appearance | High clarity, 90% light transmittance, glass-like transparent;Can be made clear, frosted, colored and UV-resistant. | Opaque, no light transmission, black/white/colored only；cannot be used as transparent viewing windows. |
| Weight | lightweight | slightly lighter |
| Impact Resistance & Toughness | Ultra-high impact strength, 250x stronger than glass, shatterproof & explosion-proof | Ordinary impact resistance, easy to crack under strong impact |
| Long-term Heat Resistance | 120–130℃ | Below 70℃, easy to deform at high temperature |
| Outdoor UV & Weather Resistance | Excellent UV resistance, anti-aging, suitable for long outdoor use | Poor weather resistance, easy to yellow & crack, indoor use only |
| Bending & Forming | Perfect for hot bending & cold bending, stable arc shape | Poor bending performance, easy to crack when heated & bent |
| Surface Hardness & Scratch Resistance | Soft surface, easy to scratch; support anti-scratch coating | Higher surface hardness, better wear resistance |
| Machining Performance | CNC cutting, seamless adhesive bonding, polishing, thermoforming | Easy drilling & tapping, not suitable for precision curved parts |
| Main Applications | Safety guards, transparent windows, outdoor glazing, arc shields | Indoor chassis, equipment housing, structural brackets, screw assembly parts |
| Material Cost | Higher unit price | Low cost, highcost performance for mass production |
Why Material Selection Matters
Choosing the wrong material can lead to:
- higher cost
- product failure
- cracking or deformation
- reduced lifespan
That’s why proper material selection is critical in custom plastic fabrication.
Which One Should You Choose?
Choose PC Sheet If:
- You need transparent viewing windows, safety shields, machine guards
- Outdoor equipment, high temperature environment
- Anti-collision, explosion-proof shatterproof requirements
- Arc bending & seamless bonding parts
Choose ABS Sheet If:
- Indoor non-transparent equipment housing, chassis, structural brackets
- Low temperature environment, large quantity low-cost parts
- Drilling, tapping, screw assembly products
- Interior decorative & structural plastic parts
