ABSTRACT:
A resilient polyurethane elastomeric article is made from (A) a prepolymer prepared from a composition consisting essentially of diphenylmethane diisocyanate and polyoxytetramethylene glycol, and (B) a dual component chain extender consisting essentially of a low molecular weight triol and a material selected form one of 1,4-butanediol and resorcinol di-(beta-hydroxy ethyl) ether. The admixture can be used to impregnate or coat porous fabric material which upon cure and be used as relatively soft, flexible seals or shock isolator pads.
