FLUORINE RUBBER COMPOSITION CAPABLE OF FORMING CRACK-RESISTANT SEALING MATERIAL AND CRACK-RESISTANT SEALING MATERIAL OBTAINED FROM THE COMPOSITION |
摘要 |
A fluororubber composition according to the present invention contains 0.1 to 3 parts by weight of a polyol compound, 0.1 to 4 parts by weight of a peroxide crosslinking agent, and 1 to 9 parts by weight of a co-crosslinking agent per 100 parts by weight of a peroxide-crosslinkable fluoropolymer. A crack-resistant seal according to the present invention contains a crosslinked fluoropolymer and a polyol compound. The crack-resistant seal according to the present invention can be formed by crosslinking the fluororubber composition, and the resultant crack-resistant seal has particularly high crack resistance. With the fluororubber composition according to the present invention, a durable crack-resistant seal having high plasma resistance, crack resistance, and compression set and that produces few particles can be formed at low cost. |
