ADIPRENE L 275 is a polyether-based liquid urethane prepolymer which is readily processable by conventional hand and machine mixing techniques similar to those used for ADIPRENE L 315. ADIPRENE L 275 produces high quality vulcanizates in the 70-75 Shore D hardness range when cured with MBCA (4,4'-methylene-bis[o-chloroaniline]). These tough, high resilience elastomers have many unique features:
ADIPRENE L 275 has a longer working life when mixed with curatives than does ADIPRENE L 315, making it more suitable for the preparation of large parts. |
