GRANULATED POWDER OF FILLED POLYTETRAFLUOROETHYLENE FOR MOLDING AND PROCESS FOR THE PRODUCTION THEREOF |
摘要 |
<p>To provide a filler-containing PTFE granular powder for molding, which has a high apparent density, a small electrostatic charge and excellent flowability and gives a molded article which is free from lowering of tensile strength and elongation and coloring attributable to a surfactant. Also a process for preparing the granular powder is provided. The granulation is carried out by wetting 100 parts by weight of a mixture of a PTFE powder and filler with 30 to 60 parts by weight of an aqueous solution containing an anionic surfactant in a concentration of not less than 10 times and less than 40 times the critical micelle concentration and then applying mechanical force to the mixture.</p> |
