Adiprene® L 325

About
ADIPRENE L 325 is a polyether-based, TDI terminated liquid urethane prepolymer that is readily processable by conventional hand and machine mixing techniques. When cured with 4,4′-methylene-bis(2-chloroaniline), this member of the ADIPRENE L family produces high quality vulcanizates in the 70-75 Shore D hardness range. These tough, highly resilient elastomers have many unique features: Excellent low-temperature flexibility Excellent abrasion resistance Good hydrolytic stability Low compression set ADIPRENE L 325 gives a longer working life when mixed with curatives than does ADIPRENE L 315, so it is more suitable for the preparation of large parts.&&
