Abstract
A fluoroelastomer (A) based on vinylidene fluoride (40-83% by moles), perfluoropropene (15-35%) and tetrafluoroethylene (0%-30%) and a diamino compound (B), are mixed with a copolymer (C) containing tetrafluoroethylene (40%-60% by moles) and propylene (60-40%). The thus obtained mixture is covulcanizable with systems based on organic peroxides. In particular mixtures are employed, containing: (A)=42-70% by weight, (B)=1-4%, (C)=51-22%, peroxide 0.4-5%, triallylisocianurate 2-4%.
