Abstract

527,951. Gas expanded materials. EXPANDED RUBBER CO., Ltd., and COOPER, A. April 24, 1939, No. 12288. [Class 70] [Also in Group IV] Closed-cell gas expanded material is produced by partly filling a mould with a thermo-plastic synthetic resin composition such as phenolformaldehyde, urea-formaldehyde, alkyd, polystyrene or vinyl chloride with or without a proportion of vulcanizable rubber mix, sealing the mould, introducing gas under pressure to permeate the composition, heating to soften the resin and while softened reducing the pressure so that the gas expands the material to fill the mould, and finally hardening the expanded material.
