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”
