Ways to Obtain Optimum Heat Resistance in Polyacrylate Elastomers 730538
This paper reviews development work in optimizing the heat resistance of polyacrylate elastomers. An expansion of the range up to 400°F, from the present 325-350°F, is currently being explored with the evaluation of fillers, curing systems, and other compounding ingredients. Data are presented comparing soap-sulfur and ammonium-type curing systems, and also for different combinations of carbon black and reinforcing mineral fillers using a soap-sulfur curing system.
