Heat-resistant crosslinked fluororubber molded product and its manufacturing method, silane masterbatch, masterbatch mixture and its molded product, and heat-resistant products

摘要

For 100 parts by mass of the base rubber containing fluororubber, 0.003 to 0.5 parts by mass of an organic peroxide, 0.5 to 400 parts by mass of an inorganic filler, and 2.0 parts by mass of a silane coupling agent A production method comprising the step (a) of preparing a silane master batch by melt-kneading an excess of 15.0 parts by mass or less at a temperature higher than the decomposition temperature of the organic peroxide, and a heat-resistant crosslinked fluororubber produced thereby Molded body, silane masterbatch, mixture and molded body, and heat-resistant product.
