INJECTION-MOLDED BODY, RESIN SLIDE BEARING, RESIN GEARWHEEL, CROWN-SHAPED RESIN HOLDER, RESIN SEAL, AND ROLLER BEARING

摘要

PROBLEM TO BE SOLVED: To improve mechanical strength, toughness and abrasion resistance of an injection-molded body while ensuring fluidity in injection molding of a resin holder, a resin seal, a resin slide bearing, or a resin gearwheel, which are injection-molded bodies.

SOLUTION: The injection-molded body is obtained by injection molding of a resin composition prepared by blending 10-40 wt.% of a fibrous inorganic reinforcing material and 0.5-10 wt.% of a polycarbodiimide resin with a biodegradable polyester polymer, in particular, a polybutylene succinate.
