Andur® 90 AP

Andur® 90 AP - polyether (PTMG) based liquid, toluene diisocyanate terminated prepolymer. An elastomer with a hardness of 90 Shore A is obtained when this prepolymer is cured with Curene 442 [4,4'-methylene-bis (orthochloroaniline)]. Elastomers of lower hardness can be obtained by reaction with various polyols and their combination with Curene 442 and other diamines, or by the use of plasticizers.
