Features & Benefits

Renewable & Sustainable Sourcing

Partially bio-circular via ISCC PLUS mass balance, reducing carbon footprint while maintaining performance. Ideal for brands targeting eco-friendly manufacturing without compromising quality.

Superior Impact & Heat Resistance

It withstands 75 kJ/m² notched impact (23°C) and 125°C heat deflection (1.8 MPa). Perfect for durable products like power tool housings or automotive parts exposed to stress.

Food-Safe & Versatile Processing

Food-contact compliant and easy to mold (low shrinkage: 0.6–0.8%). Simplifies production of kitchenware, packaging, and medical components needing clarity and safety.
