Title:
サブミクロンのポリテトラフルオロエチレン粉末の生成方法およびその生成物
Document Type and Number:
Japanese Patent JP2006527269
Kind Code:
A
Abstract:
A method for treating polytetrafluoroethylene (PTFE) in its reactor latex form to produce a dry submicron PTFE powder that remains stable without rheology modifiers, surfactants, wetting agents, pH adjusters or other stabilizing additives. Reactor latex PTFE formed during an emulsion polymerization process can be irradiated, with an electron beam or gamma rays, during or after the polymerization to form a product where the dry submicron PTFE powder is free-flowing, tends not to self-agglomerate and tends not to dust into the air upon handling so that the PTFE is readily dispersible when placed in a desired application system or medium.
