ADIPRENE L 700 is a TDI polyether-based liquid urethane prepolymer which is readily processable by conventional hand and machine mixing techniques. ADIPRENE L 700 produces high quality elastomers in the 90-94 A durometer (42-46 D durometer) hardness range when cured with 4,4'-methylene-bis (2-chloroaniline) or Chemtura's CAYTUR® 21 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

These properties suggest the use of ADIPRENE L 700 in applications such as wheels, rolls, or spraying.
