Abstract
Vulcanizable fluoroelastomer compositions having as base a copolymer of vinylidene fluoride (from 40 to 84 mol %) with perfluoropropene (15 to 30 mol %) and with tetrafluoroethylene (0.30 mol %) and containing a vulcanizing agent of the polyhydroxy compound type, an accelerator of the aminophosphinic compound type, metal oxides and/or hydroxides of basic character and an alkyl, cycloalkyl or aryl compound from the group of phosphoric esters, aminophosphoric esters, sulfoxides and sulfones.
