Product Description

Heat Shrink Tubing for Fiber Optic Closures

Heat Shrink Tubing for fiber optic closure, fiber optic closure, heat shrinkable sleeve, cable seal

Model: HSTFC

Description

Heat Shrink Tubing for Fiber Optic Closures (terminal box) is with a layer of spiral coated hot melt adhesive in the internal surface. Out layer provide reliable protection. High quality hot melt adhesive provide excellent watertight and prevent leaking from terminal box.

Features

>Resistant to UV-radiation
>High electrical insulation
>Superior mechanical property
> Temperature sensitive paint for easy operation
> One inside end without adhesive for fixing cable position
> Chemical Resistant to Liquid of 70% Isooctane and 30% Toluene for 168 hours (70/30,Isooctane/Toluene)

Operating temperature range:

>Operating temperature: -55˚C~110˚C
>Minimum shrink temperature: 80˚C
>Minimum fully recovery temperature: 120˚C
