Radiation Cross-linked Polypropylene Heat Shrinkable Tape

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".
