Andur 9500 APLF is a polyether (PPG) based liquid, toluene diisocyanate terminated prepolymer containing 0.1% or less free TDI monomer. An elastomer with a hardness of 95 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 curing Andur 9500 APLF with polyols and their combination with Curene 442 and other diamines, or by the use of plasticizers.
