It is a high-performance special material dedicated to pipeline anti-corrosion and sealing, laminated with radiation cross-linked polyethylene substrate and special sealing hot-melt adhesive layer. The substrate is manufactured through extrusion, radiation cross-linking and stretching processes to form a stable three-dimensional network structure with excellent shape memory effect. When heated, the hot-melt adhesive can form high-strength bonding with steel pipes and epoxy coatings. During construction, heat the material to 140℃–160℃; the substrate shrinks radially while the hot-melt adhesive melts to fill gaps. It seamlessly wraps pipe welds, elbows, flanges and other parts to form a sealed anti-corrosion coating.

Pressure-sensitive Adhesive Heat Shrinkable Tape (abbreviated as PSA Heat Shrink Tape) is an anti-corrosion and sealing material combining heat shrinkage performance and pressure-sensitive adhesion properties. It is laminated with radiation cross-linked polyethylene substrate and butyl rubber modified pressure-sensitive adhesive layer. The substrate offers mechanical strength and heat shrinkability, and the pressure-sensitive adhesive layer forms stable bonding with the outer surface of pipelines.

A high-performance material for pipeline anti-corrosion and sealing, it is composited of radiation cross-linked polypropylene substrate and a special hot-melt adhesive layer. The substrate is treated via radiation cross-linking technology to form a three-dimensional network structure of polypropylene molecular chains, which enhances mechanical strength, temperature resistance and anti-aging performance. The hot-melt adhesive layer melts upon heating and forms firm adhesion with steel pipe surfaces and epoxy coatings. During installation, heat is applied (typically 130℃–150℃) to trigger radial shrinkage of the substrate. The molten hot-melt adhesive evenly covers pipeline joint areas to form a tight sealed anti-corrosion coating, delivering long-term stable protection relying on the "shape memory effect".
