MEMBER ARRANGED IN WAFER STORING CONTAINER AND METHOD FOR MANUFACTURING THE MEMBER

摘要

A high-quality member installed in a wafer storage case is provided in which the wafer is not contaminated by the generated sulfur gas and the injection molding process is satisfactorily carried out. A member 1 installed in a case 2 for storing a wafer 3 is formed by injection molding a polybutylene terephthalate (PBT) resin. The PBT resin has a weight-average molecular weight (Mw) of 15000 to 20000. The member 1 installed in the wafer storage case is formed by injection molding so that the weight of sulfur in a sulfur-containing secondary antioxidant added to the PBT resin is 0.1% or less of the weight of the PBT resin.
