NFD301

Description:

Flame retardant, dual wall, UL224 flexible heat shrink polyolefin tubing. The hot melt adhesive will melt and flow to seal and encapsulate the inner components, offering excellent insulation and protection against moisture.

Features:

  1. Flame retardant UL224
  2. Adhesive lined for environmental protection
  3. High shrink ratio 3:1
  4. Very flexible
  5. Good adherence to steel, plastics & many other materials
  6. Excellent chemical, physical & electrical properties
  7. Shrink temperature  > 100°C
  8. Operating temperature -55°C to +110°C*.

* Outer wall operating temperature is -55°C to +135°C but in combination with the adhesive a safety margin has been applied
