| High Light | UV resistant heat shrink sleeve ，polyethylene pipeline anti-corrosion coating ，hot-melt adhesive field joint sleeve | ||
Polyethylene (PE) heat-shrinkable sleeves feature a two-layer structure consisting of a radiation cross-linked polyethylene backing and a specialized hot-melt adhesive. For application on steel pipelines, the shrink sleeve is used in combination with a solvent-free, two-component epoxy primer.
The hot-melt adhesive provides excellent adhesion to the PE backing, the steel pipe surface, and the epoxy primer. Upon heating, the PE backing shrinks while the adhesive layer melts, allowing the sleeve to tightly conform to the pipe joint. Together with the epoxy primer, this system forms a strong, continuous anti-corrosion barrier comparable to factory-applied three-layer polyethylene (3LPE) coatings.
This coating system offers excellent resistance to corrosion, abrasion, impact, ultraviolet (UV) radiation, and aging. In addition, it is easy to apply in field conditions.
Primarily used for pipe connection, field joint coating, wrapping around pipes, anti-corrosion of various pipe joints, and pipe repair applications. Suitable for:
