RPU 130

Strong, tough, and highly heat resistant

Strong, very tough, and highly heat resistant

RPU 130 is strong, tough, and heat resistant with an impact resistance of 76 J/m and heat deflection temperature of 119 °C. RPU 130 is composed of 30% Susterra® propanediol, a bio-based material that combines performance and sustainability. RPU 130’s unique combination of performance attributes makes it comparable to an unfilled thermoplastic like nylon and polypropylene.
