Abstract

Peroxide-cured elastomer compsns. contain (a) 50-90 wt. % of a vulcanisable fluorinated elastomer, esp. a vinylidene fluoride-hexafluoropropylene copolymer; (b) 3-15 wt. % of a liquid 1,2-polybutadiene, (c) 3-15 wt. % of an acid acceptor, esp. MgO and (d) 0-30 wt. % of a filler, esp. SiO2. The rubbers have excellent mechanical and chemical resistant properties in a temp. range of -40 to +300 degrees C, and are esp. useful for making seals and piston rings in (rotary) internal combustion engines.
