Heat shrinkable tubes act as a protective covering for
wires, terminals, joints, connections, etc., as it provides protection against
cut, impact, dust, fine particulates, moisture, chemical and abrasion. Polyolefin
is the most common material used for making heat shrinkable semi-conducting
tube and stress control tube. Other than this, FEP, PVC, PVDF and other
thermoplastic materials can also be used in the production process. Apart from
the benefit of complete protection, heat shrinkable tubes are beneficial in
achieving smooth texture, finished look, organized electrically and thermally
insulated wires. These create a seal that provides defense against
environmental conditions.
