PE heat shrinkable tape (sleeve) is composed of cross-linked polyethylene back and special heat melt adhesive. Heat melt adhesive has good bonding with PE back, steel pipe and Fusion bonded epoxy (FBE layer). By heating PE back shrinks, adhesive layer melts, and closely wraps around pipe joints, then it forms together with FBE a firm and continuous anti-corrosion body. It is resistant to corrosion, wear, impact, UV and aging, easier to be operated.
