DM0225 Dual Wall Heat Shrink Tubing, 2:1,Flame Retardant,RoHs Certified

DM0225 Dual Wall Heat Shrink Tubing, 2:1,Flame Retardant,RoHs Certified

The double-walled(Dual wall) pipe is composed of a double layer of soft flame-retardant polyolefin and hot-melt adhesive. The outer layer of polyolefin is soft, flame-retardant, and shrinks at low temperature,the inner layer of hot-melt adhesive can buffer mechanical strain and have a strong seal. Their main function is to seal, waterproof, anti-corrosion, and prevent air leakage.

Mainly used in the wire connection of electronic equipment, automobile wire harness, home wire harness, wire and cable branch, metal pipeline, wire and cable repair, submersible pump wiring and other occasions that need to be sealed.

Characteristic description

  • 2:1 shrink ratio
  • Superior sealing against water, moisture or other contaminants
  • Inner adhesive bonds to plastics, steel and polyethylene
  • Out jacket flame retardant
  • Continuous operating temperature:-45 ℃-125℃
  • Shrink Temperature:125 ℃

General Information

Mainly used in the wire connection of electronic equipment, automobile wire harness, home wire harness, wire and cable branch, metal pipeline, wire and cable repair, submersible pump wiring and other occasions that need to be sealed.
