有効である。In the present invention, silicone oil, silicone grease, or modified products thereof are blended with such fluoro rubber. These are organosilicon compounds that have a reloxane bond and a methyl group (CH) or phenyl group (C, HSJ, etc.) bonded to the silicon atom, and are usually called silicone oil or silicone grease in the form of oil or grease. Any of these and their modified products may be used, but dimethylpolysiloxane into which a methyl group has been introduced and its modified products are particularly effective.
これらの添加量は通常フッソゴム１００重量部に対し０
．５〜１０重量部が好ましい。The amount of these additions is usually 0 per 100 parts by weight of fluoro rubber.
．． 5 to 10 parts by weight is preferred.

強剤、と同時に混合することが好ましい。There are no particular restrictions on the method of mixing silicone oils and anhydrous silicic acid compounds, but before mixing the vulcanizing agent and vulcanization accelerator, they should be mixed with other additives, such as reinforcing agents such as carbon black, at the same time. It is preferable to do so.
