Product Profile: Polycarbonate
As a high-performance engineering plastic, polycarbonate stands out for its balanced thermal stability, optical transparency and processing adaptability.
✅ Excellent Thermal Resistance & Wide Working Temperature
Long-term sustainable service temperature: -60℃ ~ 120℃, maintaining mechanical toughness in both ultra-low cold and moderate heat environments
Heat deflection temperature: 130~140℃, resistant to bending and deformation under thermal load
Glass transition temperature: 149℃; thermal decomposition only occurs above 310℃, avoiding material pyrolysis during high-temperature molding and usage
✅ Premium Optical Performance & Flexible Color Customization
Visible light transmittance: 85%~90%, comparable to glass in transparency
Able to produce near-colorless transparent products with minimal light loss
Great coloring performance, compatible with various colorants to realize diverse tone customization for differentiated product design
