Production Description:
Modified PC composites overcome inherent limitations through glass fiber reinforcement (15-40% loadings) and surface-hardening treatments. Resultant grades exhibit 300% improved abrasion resistance (Taber CS-10, 1kg) and 50% reduced coefficient of thermal expansion (CTE 3.5×10⁻⁵/°C), meeting automotive LED lens and aerospace interior specifications.
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.
