Specialized in heat shrink products, Communication parts and more
Model KKHS-DW
Series Heat Shrinkable Tubing
Product Description

Semi-flexible, General purpose adhesive lined, moisture proof Heat Shrinkable Tubing

1. Application : Provides excellent mechanical, physical and electrical performance. Inner coated adhesive is melt and sealed by heat
shrinking for water and air proof.

2. Features and benefits :

(1) 3:1shrink ratio
(2)excellent flame retardant(outside layer only)
(3) Few sizes cover a wide range of diameters, allowing reduced inventory and this
tubing accommodates awkward, irregular shapes.
(4) various colors are available up on request.

3. Operating temperature range : -55℃ to 135 ℃
Minimum shrink temperature : 120℃
