Features & Benefits
Sustainable Material Choice
Partially bio-circular (attributed via mass balance), it reduces carbon footprint without sacrificing performance. Ideal for brands prioritizing eco-compliance and lifecycle transparency.
Superior UV Resistance
Built-in UV stabilization prevents yellowing and degradation in outdoor use. Ensures long-term clarity for applications like lighting covers or automotive trims exposed to sunlight.
Easy Processing & Release
Low viscosity (19 cm³/10 min MVR) and mold-release properties cut cycle times and reduce defects. Lowers production costs for complex geometries like thin-walled housings.
Use & Applications
- Outdoor Lighting: LED diffusers, streetlight covers (UV-resistant clarity).
- Consumer Electronics: Transparent device housings (scratch/impact-resistant).
- Automotive Glazing: Interior lenses, sunroof components (thermal stability).
- Industrial Shields: Safety visors, machine guards (high optical transmission).
- Renewable Energy: Solar inverter casings (weather/electrical insulation).
