Adiprene® L 300

About
ADIPRENE L 300 is a polyether-based liquid urethane prepolymer which is readily processable by conventional hand and machine mixing techniques. ADIPRENE L 300 produces high quality elastomers in the 88-92 durometer A hardness range when cured with 4,4′-Methylene-bis[2Chloroaniline] or CAYTUR® 21DA urethane curative. These tough, highly resilient elastomers have many unique features: Excellent low-temperature flexibility Excellent abrasion resistance Good hydrolytic stability Good compression set resistance The properties of ADIPRENE L 300 suggest its use in applications such as small rolls, draft gears, and spraying. The relatively short working life of mixes of ADIPRENE L 300 and MBCA can, in many cases, effect significant savings for the processor by increasing production rates via reduced demolding times.&&
