Summary: | PROBLEM TO BE SOLVED: To provide a resin-made flexible boot having an improved continuing effect of noise generation suppression while maintaining an initial noise generation-suppressing effect, and securing sealability and durability. SOLUTION: This resin-made flexible boot is molded from a molding material including a thermoplastic polyester elastomer as a base material and has a bellows part connecting a large-diameter port part to a small-diameter port part. The thermoplastic polyester elastomer is a copolymer composed of a hard segment comprising an aromatic dicarboxylic acid and low-molecular- weight glycol, and a soft segment of a molecular weight of 400-4,000. The molding material is prepared by adding at least one kind of liquid lubricant selected from mineral oil and vegetable oil, and 0.01-10 pts.wt. at least two-functional epoxy compound to the thermoplastic polyester elastomer of 100 pts.wt. |
