Abstract
A method for making high-pressure sheet gasketing material is provided that employs an elastomer, such as natural rubber and/or acylonitrile-butadiene rubber. Tert-butyl acetate is added to dissolve the elastomer. Other components may then be mixed with the dissolved elastomer and may include, for example, antioxidants, colorants, curing agents, curing accelerators, reinforcing fillers, and fibers such as organic and/or mineral fibers. The resulting dough may be formed into a high-pressure sheets, for use as gasketing material, using a two-roll sheeter machine, or the like.
