摘要：
Fluoroelastomeric compositions comprising:
A) a fluoroelastomeric matrix based on vinylidene fluoride (VDF);
B) a semi-crystalline fluoropolymer, in an amount from 1 to 40% by weight based on the total of A) + B), comprising a semi-crystalline fluoropolymer core coated by a semi-crystalline fluoropolymer shell containing bromine and/or iodine in the polymer chain;
the fluoroelastomer A) incorporates the fluoropolymer B), the fluoropolymer B) being formed by tetrafluoroethylene (TFE) homopolymers, or by TFE copolymers with one or more monomers containing at least one unsaturation of ethylene type, the average sizes of the semi-crystalline fluoropolymer particles being from 10 to 100 nm, preferably from 10 to 60 nm.
