Production Description:
-
Modified PC undergoes chemical/physical enhancements to improve UV resistance, reduce stress cracking, and meet stringent requirements in electric vehicles and medical devices.
-
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.
