WIPO Patent Application WO/2001/034666
Kind Code:
A1
Abstract:
A vulcanizable fluoroelastomer composition from which a vulcanizate reduced in compression set can be produced in a short time and which is excellent in molding stability and suitability for kneading. It comprises a fluoroelastomer having C-H bonds in the polymer chain, a vulcanizing agent, and a vulcanization aid, wherein the optimum vulcanization time for the composition, T¿90? (min), and the compression set of the vulcanizate, CS (%), satisfy the following relationships (I) and (II): Relationship (I): CS $m(F) -3.45Ln (T¿90?) + 22.8-4 x 10?-5¿ x MW, provided that 50,000 $m(F) MW $m(F) 200,000; and Relationship (II): CS $m(F) 3.45Ln (T¿90?) + 14.8, provided that 200,000 $m(F) MW.
