Application

  • Automotive forward lighting (e.g., headlamp lenses, fog lights)
  • Signal lighting components (brake lights, turn indicators)
  • Thin-wall injection-molded covers requiring optical precision and weather resistance

Features & Benefits

Optical Clarity & UV Stability

Achieve >88% light transmission (ISO 13468-2) and near-zero haze (<0.5%) for distortion-free headlamp lenses, even after years of sun exposure. Ensures compliance with automotive safety standards.

Impact Resistance Under Stress

Withstands 60J puncture energy (ISO 6603-2) and 70 kJ/m² notched impact strength (ISO 179) at 23°C. Prevents lens cracking from road debris or thermal shocks.

Thermal & Processing Efficiency

Maintains integrity at 123°C (1.8 MPa load, ISO 75) and flows smoothly at 280–320°C. Easy-release properties cut cycle times by 15% vs. standard PC resins.
