Features & Benefits

Sustainable Without Compromise

It uses bio-circular raw materials (ISCC PLUS-certified), reducing carbon footprint while maintaining premium polycarbonate properties—ideal for eco-driven industries.

Tough & Reliable Performance

Exceptional impact strength (75 kJ/m² notched Charpy at 23°C) and thermal resistance (HDT 125°C @1.8 MPa) prevent cracks in demanding applications like automotive or enclosures.

Easy Processing, Lower Waste

Optimized flow (MVR 9.0 cm³/10 min) and easy-release properties enable smooth molding at 280–320°C, cutting production downtime and scrap rates.
