Abstract

527,736. Expanded rubber. EXPANDED RUBBER CO., Ltd., and COOPER, A. April 15, 1939, No. 11511. [Class 70] The process for the production of closed-cell gas-expanded rubber or rubber-like material described in Specification 358,967 is modified by the partially vulcanized and expanded material being heated at 110-120‹C. to expand it almost to the size of the curing mould before it is placed therein for the final heating. The mould is cooled before being opened, to prevent the bursting of the gas cells which might otherwise occur.
