Andur 850 AP

Andur 850-AP is the result of several years of research to develop a high performance moderate cost prepolymer for the cast urethane industry. This product is a polyester/polyether TDI terminated coprepolymer. An elastomer with a hardness of 84 to 86 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 through the use of plasticizers.
