The Mechanical Properties of Some Polyurethane Rubbers at Room Temperature

Abstract

Article describes the casting of polyurethane rubbers and difficulties in determining Young's Modulus of such a soft rubbery material. Suitable testing procedures are recommended for the wide range of moduli from 16 to 700 lbf/in2 obtainable with different mixes of this material, their fringe‐stress sensitivities are measured and favourable technical applications are pointed out.
