Abstract
The invention pertains to peroxide-curable fluoroelastomers for the oil and gas industry, including explosive decompression, and which can be easily processed to yield cured parts in standard machineries at reasonable throughput rates, said fluoroelastomers comprising: recurring units derived from vinylidene fluoride (VDF); recurring units derived from hexafluoropropylene (HFP); recurring units derived from at least one bis-olefin [bis-olefin (OF)] having general formula: wherein R, R, R, R, Rand R, equal or different from each other, are H, a halogen, or a C-Coptionally halogenated group, possibly comprising one or more oxygen group; Z is a linear or branched C-Coptionally halogenated alkylene or cycloalkylene radical, optionally containing oxygen atoms, or a (per)fluoropolyoxyalkylene radical; and iodine or bromine cure-sites;said fluoroelastomers further possessing a Mooney viscosity (ML) of at least 85 MU (1+10@121° C.), when measured according to ASTM D1646.
