Production Description:
Advanced PC formulations address virgin material limitations through molecular reinforcement and nano-additives. Post-modification, the material achieves UL94 V-0 flammability ratings without sacrificing 150°C HDT, while resolving environmental stress cracking in fuel/ethanol exposures. Ideal for EV battery housings and surgical instrument handles requiring chemical/thermal duality.
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.
