Title:
FINE POWDER OF MOLTEN HIGH-MOLECULAR-WEIGHT FLUORORESIN, MOLDED ARTICLE THEREOF, AND PROCESS FOR PRODUCING BOTH
Document Type and Number:
WIPO Patent Application WO/1996/003446
Kind Code:
A1
Abstract:
A fine powder of a molten high-molecular-weight fluororesin having a melt viscosity of 108-1013 P, an apparent density of 0.4-1.5 g/cc, and a specific surface area of 2 m2/g or less. A molded article produced from this fluororesin, which has not been utilized heretofore, is reduced in the bleeding of particles, particularly suitable for use in a semiconductor making process, and capable of improvement in bending fatigue resistance, wear resistance, and so forth.
