Production Description:

As a carbonate-containing polymer family, PC's molecular architecture enables unique combinations of toughness and transparency. While multiple structural variants exist (alicyclic, aromatic-aliphatic hybrids), commercial grades predominantly utilize bisphenol A monomers, yielding materials with tensile strengths ~70 MPa and notched Izod impact resistance exceeding 800 J/m.

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.
