ALIPHATIC POLYESTER COMPOSITE MATERIAL AND MOLDED PRODUCT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an aliphatic polyester composite material that has simultaneously improved impact strength and heat resistance wherein the impact strength and the heat resistance have both sufficiently high values and well-balanced, and provide molded products through the melt-molding process. SOLUTION: This aliphatic polyester composite material comprises an aliphatic polyester and calcium carbonate where the content of calcium carbonate is 0.1 to 5 wt.% in the composite material and the aliphatic polyester in the composite material has a crystal average particle size of≤100μm.
