BSTSGeneral purpose, thick walled heat-shrinkable tubing

  • shrink ratio 3 : 1
  • temperature range: -55 °C to 110 °C
  • good resistance to fluids and chemicals
  • high mechanical strength
  • heavy wall construction
  • EU ELV
  • EU RoHS

BSTS heat-shrinkable tubing is made of a rugged polymer that resists moisture, fungus, and weathering. It also has excellent electrical properties. This tubing is useful in applications where insulation, abrasion resistance, and strain relief are important. When used with sealant tape, it can provide a watertight system in non-pressurized applications.
