Abstract

A compression pad for use in a die is composed of a substance comprising a cured polytetramethyleneether polyurethane having a modulus at 100% elongation of 1500 to 4500 lb./sq. in., elongation at break of 200 to 500%, a Shore D hardness of 45 to 80 and an Izod impact strength minimum at 23.9 DEG C. of 10 foot lb./inch of notch. The polyurethane is prepared by the prepolymer method and cured with a diamine, e.g. p,p1-methylene bis-(ortho-chloroaniline). Finely ground metal particles, e.g. steel or aluminium, may be added to the polyurethane. In a typical example (3) a prepolymer derived from tolylene diisocyanate and polytetramethyleneether glycol was reacted with p,p1-methylene bis-(ortho-chloroaniline) and crushed steel particles added and cast into a compression pad mould for a door panel.
