Document Type and Number:

WIPO Patent Application WO/2003/064131

Kind Code:

A1

Abstract:

The invention provides a process for producing a reclaimed fluororubber from a waste fluororubber vulcanizate through revulcanization; a composition for the above revulcanization; and reclaimed fluororubber vulcanizates. A process for production of reclaimed fluororubber vulcanizates which comprises converting a waste fluororubber vulcanizate (A) into a devulcanized fluororubber (B) by thermal treatment and then subjecting the devulcanized fluororubber (B) to vulcanization (2) to form a reclaimed fluororubber vulcanizate (C), characterized in that the waste fluororubber vulcanizate (A) is one obtained by vulcanization (1).
