Zusammenfassung: | PROBLEM TO BE SOLVED: To obtain a polyester elastomer composition usable in a field required to have flexibility and abrasion resistance, especially as hose, belt, tube and grip, more particularly a polyester elastomer composition having excellent flexibility, abrasion resistance, grease resistance, adhesivity to a substrate, or the like, free from the contamination to the appearance and environment and usable under a severe condition. SOLUTION: The polyester elastomer has (A) a surface hardness of ≥90A, (B) an abrasion of ≤3 mg by Suzuki's thrust-type abrasion test and (C) a volume swelling ratio of ≤20% by a grease-resistance test.
