CELLULOSE ESTER BASED COMPOSITES FOR EYEGLASS FRAME

摘要

PURPOSE: A cellulose ester-based composite is provided to improve the heat flow of cellulose acetate, thereby conducting injection molding. CONSTITUTION: A cellulose ester-based composite comprises a cellulose ester and a polyalkylene glycol as a base material. The comprised amount of the cellulose ester is 50-90 weight% and the amount of the polyalkylene glycol is 10-50 weight% based on total the weight of the base material. The composite additionally comprises one or more additives selected from a filler, an oxidation preventing agent, dye, and a pigment. The comprised amount of the additive is 1-5 parts by weight based on 100.0 parts by weight.
