Abstract

PURPOSE: To improve chemical resistance, thermal resistance and recuperative property in constitution by making a tube mainly with use of material composed of block co-polyester in ratio of special value.
CONSTITUTION: The tube is made of an elastic material that has mean molecular weight within bounds of approximately 300W5000 in formulation of soft segment composed of polyoxyalkyleneglycol which has 2.0W4.5 of carbon number to oxygen number ratio and aliphatic polyester together with hard segment composed of aromatic polyester resulting in block co-polyester, the proportion of this soft segment occupies 20W80 weight % of block co-polyester, and insoluble portion is bridged so that it may be 20 weight % or more to orthochlorophenol. The above- mentioned material can obtain the tube which is experimentally excellent in chemical resistance, thermal resistance and recuperative property.
