Document Type and Number:
WIPO Patent Application WO/2017/094699
Kind Code:
A1
Abstract:
[Problem] To provide a polyurethane tube having a small bending repulsive force and superior inner-pressure creep characteristics in a flexible polyurethane tube. [Solution] The present invention is a polyurethane tube with a bending repulsive force of 0.035 N/mm2 or less, wherein the polyurethane tube is formed so that the difference between the storage elastic modulus E'30 at 30 °C and the storage elastic modulus E'80 at 80 °C is 15% or less of E'30.
