POLYVINYL CHLORIDE-FREE MEDICAL TUBE WHICH IS MANUFACTURED WITH A ONE LAYERED OR MULTI-LAYERED STRUCTURE WITH CROSS COPOLYMERIZATION OLEFIN-AROMATIC VINYL-DIENE COPOLYMER HAVING SHORE HARDNESS BETWEEN 40A AND 100A, MOLDED PARTS, AND MEDICAL TREATMENT SUPPLIES THEREOF

摘要

PURPOSE: A PVC(PolyVinyl Chloride)-free medical tube, molded parts thereof, and medical treatment supplies thereof are provided to manufacture the PVC-free medical tube, the molded parts, and the medical treatment with excellent kink resistance, tenacity, transparency, and anti-adsorbability of medicine, molded part thereof, and medical treatment supplies thereof.;CONSTITUTION: A PVC(PolyVinyl Chloride)-free medical tube includes cross copolymerization olefin-vinyl aromatic compounds-diene copolymer whose shore hardness is between 40A and 100A, or a composition including the same. The composition layer is obtained by adding syndiotatic1, 2-polybutadiene, and 10 to 200 parts by weight of the mixture of the syndiotatic1, the 2-polybutadiene to 100 parts by weight of cross copolymerization olefin-vinyl aromatic compounds-diene copolymer whose shore hardness is between 40A and 100A. The PVC-free medical tube is formed as one layer between the layers which are composed of either cross copolymerization olefin-vinyl aromatic compounds-diene copolymer whose shore hardness is between 40A and 100A, or a composition layer including the cross copolymerization olefin-vinyl aromatic compounds-diene copolymer.;COPYRIGHT KIPO 2013
