Tough 1000 Resin is a ductile, impact-resistant material with comparable strength, stiffness, and toughness to high-density polyethylene (HDPE), designed with exceptional wear and fatigue resistance for long-term toughness and utility. The 180% elongation at break (EAB) and Gardner impact strength of 128 in-lb surpass HDPE, making it ideal for parts that bend, compress, or deform without cracking. Hinges and functional parts can handle repeated stress and wear with a work of fracture of 3,200 J/m 2 and a Ross flex fatigue of >100,000 cycles (at 23 °C). With a matte, dark grey color, Tough 1000 Resin is engineered for applications that require smooth surfaces and low-friction finishes. Download Technical Data Sheet Why Choose Tough 1000 Resin? Ductile, impact-resistant material with toughness that rivals high-density polyethylene (HDPE). Durable and Ductile Elongation at break of 180% and Gardner impact strength of 128 in-lb surpass HDPE, for durable enclosures and components that withstand significant impact. Exceptional Fatigue Resistance and Toughness Produce jigs, fixtures, and functional parts that experience repeated stress and wear with a work of fracture of 3,200 J/m 2 and a Ross flex fatigue of >100,000 cycles (30 degree deflection at 1 Hz). Environmentally Stable Parts for End-Use Applications Improved temperature, creep, and aging resistance compared to Durable Resin. Parts resist warping and sagging at corners and edges Low-Friction and Wear-Resistant Comparable lubricity to Delrin (POM), for surfaces that slide against each other without abrasion or scratches. Ideal for moving assemblies such as hinges, gears, and fixtures. Which Material is Right for you?
