  • Durable transparent covers for sensors/electronics
  • UV-exposed exterior parts requiring color stability

Features & Benefits

Eco-Certified Recycled Content

This ISCC PLUS-attributed resin uses chemically recycled post-consumer materials, reducing environmental impact while meeting stringent automotive sustainability goals.

Superior Optical Performance

With 89% light transmittance (1mm) and <0.5% haze, it ensures crystal-clear lenses for headlamps, maintaining UV stability under harsh outdoor conditions.

Reliable Processing & Durability

Medium viscosity enables smooth injection molding (280–320°C), while high impact strength (70 kJ/m²) and 123°C heat deflection prevent warping/cracking in demanding applications.
