Heat Shrink Tube

A specialised and cost-effective heat shrink tube with a low percentage of shrink for use in insulating thermal protectors.

Plamec Heat-Shrink Tubing is the preferred material for the insulation of Thermal Protectors and Hermetic Systems. The material remains flexible after shrinking and provides an improved appearance as depicted in the photograph. Plamec Tubing maintains high dielectric strength and cut through resistance, up to temperatures of 160 ̊C.


  • 10% to 16% shrinkage at 150 ̊C which secures and insulates the metal cores of components and batteries
  • Excellent dielectric and cut through resistance
  • Constructed from UL recognised film under E348131
  • Wall thickness starts from 0.050mm
  • More features available with internal diameters of 2 to 200mm
  • Close tolerance of internal diameter and reliable concentricity provide quick and reliable assembly
  • Roundness and concentricity lead to automated application, supplied and cut to customer requirements
