Wrap around sleeves

Heat Shrinkable Wrap Around Sleeves are mainly used for repairing outer/inner sheath of cables.These sleeves are also used for providing corrosion protection to the metallic parts of the cables that are exposed to polluted environment and for making Telecommunication cable joints.
The Wrap Around Sleeves are made from thermally stabilised cross linked weather resistant polymeric material. The Sleeves are coated internally with Hot MeltAdhesive.The outer surface of the Sleeves have thermocromic paint.
