FLUORORUBBER COMPOSITION, CROSSLINKED FLUORORUBBER, PROCESS FOR PRODUCTION OF THE SAME, AND CROSSLINKED FLUORORUBBER FOR O-RINGS

摘要

[PROBLEMS] provides transfer fluoro-rubber composite, be not exposed in this way the extrusions talcum bloomed in heat-resisting, low temperature resistant, colorable fluorubber and can provide product with same function and material that conventional batch produces and its to significantly reduce rejection rate prepare raw material; With manufacture crosslinked fluororubber. [MEANS FOR SOLVING PROBLEMS] composition is comprising the fluorubber as necessary component by the fluoropolymer of peroxide cure, peroxide crosslinking agent, heat-resistant filler includes that calcination of talc has water-wetted surface, it is characterized in that the calcination of talc is preferably value -40 of the low form ternary fluoropolymer with TR10 to -25 °C for the fluoropolymer of 2 to 20 parts by weight, 100 parts by weight fluoropolymer and this peroxide cure, it is still preferred to vinylidene fluoride/perfluor (methyl vinyl ether)/tetrafluoroethylene terpolymers.
