Title:
Fluorocarbon rubber constituent
Document Type and Number:
Japanese Patent JP6020107
Kind Code:
B2
Abstract:
Provided is a fluororubber composition which does not deteriorate workability during roll kneading, does not cause foaming during crosslinking and molding, and is capable of giving a crosslinked molded article which exhibits desired hardness and sealing property without using a reinforcing inorganic filler such as carbon black and silica. The fluororubber composition includes, relative to 100 parts by weight of a vinylidene fluoride-copolymerized, fluorine-containing elastomer copolymer having a glass transition temperature and a melting point, no reinforcing inorganic filler 5 to 100 parts by weight of a PTFE filler, 0.5 to 10 parts by weight of a polyol crosslinking agent, 1 to 15 parts by weight of magnesium oxide, and 0.1 to 2 parts by weight of hydrotalcite. Preferably, 0.1 to 10 parts by weight of a quaternary onium salt crosslinking accelerator is further included.
