Chemtura -Pushing the Limits of Polyurethane Elastomers

ADIPRENE® High

Temperature Urethanes

High Temperature Toughness Up to 150°C

Hydrolysis Resistance

Oil Resistance

“Many new markets have not been exploited by urethanes in applications

requiring a combination of high temperature

performance, hydrolysis and oil resistance”

“Chemtura’s Urethanes Succeed Where Others Fail”
