Adiprene® L 767

About
ADIPRENE L 767 is a TDI polyether-based liquid urethane prepolymer which is readily processable by conventional hand and machine mixing techniques. ADIPRENE L767 produces high quality elastomers in the 62D durometer hardness range when cured with 4,4′-methylene-bis (2-chloroaniline), and the 53 D durometer hardness range when cured with CAYTUR® 21DA. These tough, highly resilient elastomers have many unique features: Excellent low-temperature flexibility ?- Excellent abrasion resistance ?- Good hydrolytic stability ?- Good compression set resistance These properties suggest the use of ADIPRENE L 767 in applications such as wheels, rolls, or spraying.&&
