Production Description:
Flame-retardant PC compounds meet UL94 V-0 standards in EV charging ports and miniaturized
power modules.
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.
