FILLED POULTRY POULTRY AND PROCEDURE FOR THEIR PRODUCTION

摘要

Filler-containing polytetrafluoroethylene granular powder, which has a large apparent density, a small average particle size and a sharp particle size distribution and a superior powder flowability, and gives a molded product having a superior tensile strength, elongation and surface roughness, and a process for preparing the same. The granular powder is prepared by granulation of a mixture of a PTFE powder and a filler in water with stirring in the presence of an organic liquid forming liquid-liquid interface with water and a nonionic surfactant.
