Product Description
Heat-shrinkable End Cap
Heat-shrinkable End Cap is used for thermal insulation of pipeline joint as well as corrosion protection, watertight seal, moisture resistance at the weld joint area. Heat shrinkable End Cap is made from a specially formulated cross-linked polymer and is fully lined with a high performance, mastic adhesive.
This combination provides a high quality, reliable system for the corrosion protection .
Heat-shrinkable End Cap Features & Benefits:
•.. Efficient and convenient in application.
•.It can also protect long-distance heat insulating material from damage and decay, so as to reduce' heat loss, cost of repair .
•. This product is characterized by chemical medium corrosion resistance and long aging resistance time, being strong to glue the relay, install simple and easy to operate
•. The hot-melt adhesive binds well with other anticorrosion layers, which enables it to be waterproof and airproof, and have natural-repair ability.
.•. signed to provide a water tight seal and prevent water access to the exposed insulation at the weld joint area. Shrinks to conform to the profile of the insulated pipe Protects the insulation during storage and transportation
