ADIPRENE R990 is an MDI-terminated polycarbonate prepolymer. The system can be processed either as a 2 component or 3 component system. The system creates PU elastomers with excellent chemical resistance. As a 2 component system when reacted with 1,4 Butane Diol it will yield a 95A elastomer. As a 3 component system it will yields elastomers in the hardness range from 65A – 95A via the use of 1,4 Butane Diol & Vibracure R613.
