FINE POWDER OF MOLTEN HIGH-MOLECULAR-WEIGHT FLUORORESIN, MOLDED ARTICLE THEREOF, AND PROCESS FOR PRODUCING BOTH

摘要

The fine powder of high molecular weight fluorine containing resins having melt viscosities of 10<6> to 10<13> poise, apparent density of 0.4 to 1.5 g/cc, and specific surface area of 2 m<2>/g or less, mold goods of the fine powder and these production methods. By utilizing the fine powder of high molecular weight fluorine containing fused resins that have previously not been employed, the mold goods obtained from the fine powder have fewer liquated particles and have become the most suitable especially for manufacturing semiconductors. The powder's products have greater resistance to flex fatigue, abrasion resistance, etc.
