Thermo Tube

THERMO TUBE is a universal high tech co extruded polyolefin dual wall shrink tube, with integrated meltable adhesive and sealant.
THERMO TUBE provides a wide range of applications where mechanical protection and or moisture proof protection of components and interconnections is required.
THERMO TUBE ,when heated, shrinks to a ratio 3/1. At the heat application the adhesives melts. During this process the adhesive transfers to a sealant and protects the application against water, humidity and chemicals.
Due its low shrink temperature, THERMO TUBE is easy to apply and has a high temperature resistance. Because of the high shrink rate only eight sizes are necessary to reach most applications.

  • Seals and protects components and interconnections
  • Water and humidity resistant
  • Stays permanently flexible
  • Application directly on copper, metals, aluminium, steel, plastics (PE)
  • Adapts to any shape
  • Low shrink temperature
  • Flame retardent
  • High UV resistance
  • High chemical resistance
  • Anti rodent application
  • RoHS compliant
