Durable and Transparent PC Clear Solutions for Automotive Applications

1. PC (Polycarbonate)

✅ Light Transmittance: 88%-92%
✅ Impact Resistance: Excellent, highly durable, and shatter-resistant
✅ Heat Resistance: High, can withstand temperatures above 120°C
✅ Weather Resistance: Moderate, tends to yellow under UV exposure (requires UV coating or additives)
✅ Flexibility: Good, can bend without breaking, but prone to stress cracks
✅ Processing: Requires precise control during injection molding to avoid residual stress
✅ Cost: Higher than PMMA

Common Applications of PC

✅ Automotive light guides (e.g., ambient lighting, dashboard indicators)
✅ Headlight lenses and exterior lighting components (due to heat resistance)
✅ Industrial lighting and optical display panels

2. PMMA (Polymethyl Methacrylate / Acrylic)

✅ Light Transmittance: 92%-94% (higher than PC, comparable to glass)
✅ Impact Resistance: Poor, brittle and prone to cracking
✅ Heat Resistance: Moderate, long-term use up to 80°C
✅ Weather Resistance: Excellent, UV-resistant, does not yellow easily
✅ Flexibility: Low, rigid and prone to breakage under impact
✅ Processing: Easy to mold, cut, polish, and laser engrave
✅ Cost: Lower than PC

Common Applications of PMMA

✅ Ambient lighting light guides (for automotive interiors, where impact resistance is not critical)
✅ LED light covers and diffusers (where high optical clarity is needed)
✅ Display panels and advertising signs (due to excellent transparency and UV resistance)
