Production Description:
Chemically stabilized PC variants utilize UV-absorber masterbatches and anti-static coatings to achieve weatherability Class 1 (ISO 4892) and surface resistivity 10⁶-10⁹ Ω/sq. These food-contact compliant grades (FDA 21 CFR 177.1580) prevent microbial adhesion in medical tubing and dishwasher-safe food containers.
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.
