Production Description:
The PC polymer class combines optical clarity (refractive index 1.586) with intrinsic flame retardancy (LOI 25-27%). Dominant bisphenol A grades (Td 380°C) exhibit specific volume resistivity 6×10¹⁶ Ω·cm and dissipation factor 0.0005-0.001 @1MHz, enabling applications from MRI machine components to spacecraft windows.
Key Advantages Over Standard PC:
-
Tailored Performance: Balances transparency, strength, and processability for niche uses.
-
Cost Reduction: Blends like PC/ABS lower material costs while maintaining core properties.
-
Durability: Enhanced UV, chemical, and thermal stability for harsh environments.
-
Regulatory Compliance: Meets flame safety (UL94), food contact (FDA), and medical standards.
