Definitions

  • the difference between the 80 'storage modulus E at 30 and 80 ° C.' storage modulus E at 30 ° C. is not more than 15% of E '30.
  • the tube is oriented in the extrusion direction (MD direction) by extrusion.
  • a tube tends to be easily deformed in the orientation direction when the orientation is aligned.
  • deformation of the tube that is, creep can be suppressed.
  • annealing rearrangement of molecules (hard segments) occurs, stabilizing while maintaining the orientation state at the time of molding, and cross-linking of molecules is promoted. Molecular cross-linking can be confirmed by an increase in MFR.
  • Polyurethane which is a material constituting the tube of the present embodiment, is generally composed of a soft segment composed of a polyol component, a low molecular glycol, and a hard segment composed of a diisocyanate component.
  • a polyol used in the tube of this embodiment an ether-based polyol such as polytetramethylene ether glycol (PTMG) is used, and as the diisocyanate, an aromatic diisocyanate such as 4,4-diphenylmethane diisocyanate is used. .
  • PTMG polytetramethylene ether glycol
  • the polyurethane tube of the present invention mounts control devices such as automobiles and airplanes as well as electronic devices such as computers, as well as tubes for flowing fluids such as gas and liquid, such as pneumatic tubes for machines and devices, in a narrow part. It can also be applied to the control circuit of a machine that needs it.

Abstract

Le problème décrit par la présente invention est de fournir un tube en polyuréthane présentant une faible force de répulsion à la flexion et d'excellentes caractéristiques de fluage sous pression interne dans un tube souple en polyuréthane. La solution selon la présente invention est un tube en polyuréthane ayant une force de répulsion à la flexion inférieure ou égale à 0,035 N/mm2, le tube en polyuréthane étant formé de sorte que la différence entre le module de conservation E'30 à 30 °C et le module de conservation E'80 à 80 °C est inférieure ou égale à 15 % de E'30.
