The present invention provides a curable fluoroelastomer composition comprising:(a) a fluoroelastomer comprising a cure site component having a halogen capable of participation in a peroxide cure reaction;(b) an organic peroxide; and(c) a siloxane or silazane comprising one or more -SiH groups.The curable fluoroelastomer compositions generally show improved processing and the resulting cured fluoroelastomers generally have improved mechanical and physical properties.
L'invention se rapporte à une composition de fluoroélastomère durcissable contenant : (a) un fluoroélastomère comprenant un composant de site de durcissement avec un halogène capable de participer à une réaction de durcissement par peroxyde ; (b) un peroxyde organique ; (c) un siloxane ou un silazane contenant un ou plusieurs groupes SiH. Les compositions de fluoroélastomères durcissables présentent généralement un meilleur comportement au façonnage et les fluoroélastomères durcis obtenus possèdent, d'une manière générale, de meilleures propriétés physiques et mécaniques.
