ADW - Heat shrinkable tube for fiber optic splice closure

ADW - Heat shrinkable tubing for fiber optic splice closure

It’s a heavy wall heat shrinkable tubing with inner spiral polyamide hot melt adhesive coated. The outer heavy wall can provide reliable external protection, and high-performance hot melt adhesive can provide dependable waterproof performance and prevents leakage of the gas inside the closure.
Operating temperature range:
  • Continuous operating temperature: -55˚C~110˚C
  • Minimum shrink temperature: 80˚C
  • Full recovery temperature: Above 120˚C
  • Discoloration temperature of temperature sensitive paint: 230˚C


Standard color: black (Special sizes are available on request.)
