FILTER FOR RESIN FILTRATION AND METHOD OF PRODUCING THERMOPLASTIC RESIN FILM

摘要

PROBLEM TO BE SOLVED: To provide a method of producing a high quality film scarcely contaminated with coarse particles and foreign substances by decreasing the adhesion and/or deposition of outside particles and impurities to and/or on the surface of a filtration material.

SOLUTION: A thermoplastic resin film is produced by using the filter for resin filtration produced from a filtration material of a metal sintered body having a surface potential at pH=6 in the range not lower than -50 mV and not higher than -10 mV.
