Process for preparing filled polytetrafluoroethylene molding powder |
摘要 |
A process for preparing a filled agglomerated polytetrafluoroethylene molding powder having a high flowability by agitating finely-divided polytetrafluoroethylene particles and a filler in an aqueous medium. While agitating a hydrophilic filler treated with an aminosilane compound in water in the presence of a higher fatty acid and/or an anionic surface active agent, the polytetrafluoroethylene particles and a water-immiscible organic liquid are added to water in that order, whereby most of the filler used can be uniformly incorporated into the agglomerated product without causing separation into the aqueous medium.
