Production Description:
Chemical-resistant PC grades incorporate fluoropolymer layers (ETFE/THV) via coextrusion, achieving 24hr NSS resistance (ASTM B117) and 500hr fuel C immersion stability. Automotive fuel system components and industrial chemical valves benefit from this multilayer barrier technology.
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.
