Features & Benefits

Food-Safe & Globally Compliant

It meets stringent food-contact standards, ensuring safety for food containers, utensils, and packaging without compromising material performance.

Effortless High-Temp Processing

It flows smoothly at 280–320°C (barrel) and 80–120°C (mold), reducing cycle times and warpage for complex geometries like thin-walled housings.

Extreme Impact Resistance

It withstands harsh environments (130% elongation at break, 70 kJ/m² notched Charpy impact), preventing cracks in toddler cups, power tool housings, or automotive parts.
