What Is Polycarbonate (PC)?
Machining of PC
Polycarbonate (PC) is a high-performance transparent thermoplastic known for its exceptional impact strength, optical transparency, and dimensional stability.
Compared to acrylic (PMMA), polycarbonate provides significantly higher toughness and impact resistance while maintaining excellent transparency.

PC (Polycarbonate) vs PEEK: Which High-Performance Plastic Should You Choose?
PC (polycarbonate) and PEEK are both strong engineering plastics, but they serve very different application ranges. This comparison helps you decide which material fits your project.
| Property | PC (Polycarbonate) | PEEK |
|---|---|---|
| Max Service Temperature | 120-130°C | 250°C (480°F) |
| Impact Resistance | Excellent (250x stronger than glass) | Good |
| Tensile Strength | 60-70 MPa | 95-100 MPa |
| Light Transmission | 85-90% transparent | Opaque (natural beige) |
| Chemical Resistance | Good (oils, greases) | Excellent |
| Wear Resistance | Moderate | Excellent |
| Moisture Absorption | Low (0.15%) | Very Low (0.1%) |
| UV Resistance | Poor (requires UV stabilizer) | Good |
| Machinability | Excellent | Good (requires experience) |
| Relative Cost | $$ | $$$$ |
| Best For | Safety shields, machine guards, medical device housings, transparent components, high-impact structural parts | Medical implants, semiconductor parts, aerospace components, extreme temperature and chemical environments |
Choose PC (Polycarbonate) if you need exceptional impact resistance, optical transparency, and a cost-effective material for housings, guards, and medical devices operating under 130°C. Choose PEEK if your application requires continuous operation at high temperatures (up to 250°C), superior chemical resistance, or biocompatibility for medical implants.
