Title:
TUBE
Document Type and Number:
Japanese Patent JP2020029954
Kind Code:
A
Abstract:
To provide a tube excellent in flexibility and low out-gas characteristics, and excellent in productivity of a molded article.SOLUTION: Thermoplastic urethane resin having a tensile modulus of elasticity (tensile speed of 200 mm/min) of 3.3 MPa or less and a diffusion coefficent of less than 1.00×10m/s in the form of a resin sheet with thickness of 1.7 mm is used for a tube of this invention. In the thermoplastic urethane resin, it is preferable that the difference between a temperature (°C) at which a storage modulus E' is 1 MPa and a glass-transition temperature (°C) is equal to or higher than 180°C. The glass-transition temperature of the thermoplastic urethane resin is preferably -10°C or lower.SELECTED DRAWING: None
