Andur 1-83 AP/Curene® 442 Anderson Polyurethane (Polyether, TDI)

Product Description
Andur 1-83 AP is a polyether (PTMG) based liquid, toluene diisocyanate terminated prepolymer. An elastomer with a hardness of 83-85 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 1-83 AP with polyols and their combination with Curene 442 and other diamines, or through the use of plasticizers.
