Features & Benefits
Sustainable & ISCC-Certified
Partially bio-circular via ISCC PLUS mass balance, reducing carbon footprint by 20–30% vs. virgin plastics. Supports eco-friendly manufacturing without performance trade-offs.
High Reflectance & Durability
It delivers 96–97% light reflection (JIS 8722) with UV stabilization. Ensures long-term brightness for optical components, resisting yellowing or degradation.
Easy Processing & Efficiency
Low viscosity (MVR 19 cm³/10 min) enables fast fills and easy demolding. Reduces cycle times by 15% and minimizes scrap in complex geometries.
Use & Applications
- LED Lighting: Reflector cups and diffusers for consistent brightness.
- Automotive: Signal lenses and sensor housings with UV resistance.
- Consumer Electronics: High-gloss bezels and optical sensor covers.
- Industrial: Reflective safety components and durable housings.
