Injection molded article used with a photosensitive material

摘要

Injection molding is performed by using a thermoplastic resin composition including a thermoplastic resin of 30 wt. % or more, a lubricant and an antioxidant. The thermoplastic resin is polymerized with a single-sight catalyst and has molecular-weight distribution of 1.1-5.0. The thermoplastic resin polymerized by using the single-sight catalyst is used for an injection molded article so that the injection molded article is superior in physical strength and blocking proofness. By adding the lubricant and the antioxidant to the thermoplastic resin composition, lubricity and antioxidant thereof may be improved.
