Production Description:
PC - the transparent engineering polymer - features interconnected carbonate groups enabling unique ductility. With melt flow indices (MFI) ranging 5-25 g/10min (300°C/1.2kg), bisphenol-A-based variants (MW 30k-100k) dominate markets for safety glazing and electronic housings requiring 140°C continuous service temperatures.
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.
