  • Light Guides: Automotive dashboards, backlit displays.
  • Precision Lenses: LED streetlights, stage lighting, VR/AR optics.
  • Injection-Molded Optics: Thin-wall sensor covers, medical device windows.

Features & Benefits

Sustainable Optical Performance

It combines 30% bio-circular content (mass balance) with industry-leading clarity (>90% transmittance), reducing carbon footprint without sacrificing optical quality—ideal for eco-conscious lighting brands.

Flawless Molded Optics

It delivers <0.5% haze and minimal yellowing (YI <1.0), ensuring crisp light diffusion in lenses and light guides, even in complex thin-wall designs.

Easy High-Yield Processing

Low viscosity (MVR 34 cm³/10min) enables fast fills and easy release at 250–300°C melt temps, cutting cycle times and scrap rates for cost-efficient production.
