ABSTRACT:
A heat-resistant plastic tube is mainly made of a polyester-based elastomer and exhibits a change amount in angle of ±10° or less in a shape retainability performance test, a change rate in inner diameter of ±2% or less in a dimensional stability performance test, a change rate in yield strength of ±30% or less in a flexibility retainability performance test. The heat-resistant plastic tube can be subjected to a thermal bending at a temperature in a use environment or higher and exhibits excellent retention of the bent shape through the thermal bending after being left in the use environment.
