摘要 |
<p>This invention provides a tetrafluoroethylene (TFE) copolymer resin powder composition capable, upon rotational lining, of generating a corrosion-resistant, nonstick film, which is a thick film on a metal or a like substrate, essentially free of gas bubbles, and excellent in adhesion and peel resistance. The TFE-copolymer resin powder composition comprises granules which comprise particles of a TFE/perfluoro(alkyl vinyl ether) copolymer (PFA), polyphenylene sulfide (PPS) particles having an average particle size of 0.3-50 mu m, and a heat resistant filler. This invention also provides a process for manufacturing the TFE copolymer resin powder composition comprising either (1) granulating a mixture of PFA particles, PPS and a heat resistant filler in the presence of water and an organic liquid, or (2) mixing PFA, PPS, and a heat-resistant filler, compression-molding, and pulverizing.</p> |
