<p>A process for producing a filled fluororesin sheet, characterized by comprising a step in which a resin composition for sheet formation comprising a fluororesin, a filler, and a processing aid is rolled at a roll temperature of 40-80‹C, the processing aid comprising 30 mass% or more (based on the processing aid) petroleum hydrocarbon solvent having a fractionation temperature of 120‹C or lower. Thus, a filled fluororesin sheet is provided which, even when the degree of loading with the fluororesin is low and the degree of loading with the filler is high, combines high stress relaxation properties with high airtightness (sealing performance). ® KIPO & WIPO 2009</p> |
