Adiprene®

Adiprene® pPDI and LF pPDI urethane prepolymers, the latter with <0.1% free isocyanate, offer elastomers designed to withstand extreme conditions, where excellent resistance to high and low temperature, water, and chemicals is critical to performance and long part life. They are often used in dynamic applications because of their long life with very low heat build-up from hysteresis and superior fatigue resistance.

Selected Adiprene® pPDI and LF pPDI prepolymers can outperform hydrogenated nitrile butadiene rubber (HNBR) at temperatures as high as 150°C (302°F), opening new application opportunities with performance beyond typical polyurethane elastomers.

Adiprene® pPDI (conventional) and LF pPDI (low free) prepolymers are available with a wide range of polyol backbones. LANXESS scientists can work with you to customize a special formulation to achieve your ideal performance.
