Abstract
Provided is a co-curable blend comprising (a) a fluoroplastic comprising (i) bromine atoms, iodine atoms, and combinations thereof, and (ii) units derived from a fluorinated monomer, and a peroxide curable fluoroelastomer gum. The invention also provides a composition comprising a fluoroplastic comprising (i) bromine atoms, iodine atoms, and combinations thereof and (ii) units derived from a fluorinated monomer, peroxide curable fluoroelastomer gum, a peroxide curative, and optionally a coagent. The fluoroplastic has an MFI no greater than 5 g/10 min., and/or an average particle size greater than 100 nm. The invention also provides a method of making a fluoropolymer blend and cured articles.
