Heat Shrinkable Sleeve Tape for Underground Buried Steel Pipe & Insulated Pipe Repair
Radiation Cross-Linked heat shrinkable sleeve is mainly used in field girth weld coating, anti-corrosive thermal insulated pipe; waterproof pipe joints of plastic water supplying and drainage water pipe.
The process flow of Huashida heat shrink tape extrusion line:
First step, the PE back film extrusion line produces PE film as clients' requirements,and second sent the PE back film to professional irradiation company to do radiation crosslinking treatment with right radiation does, so that the sleeve has Good fire resistance and tensile strength;Third step put the irradiated back film into the heat shrinkable sleeve adhesive coating production line for adhesive coating. In this process, the heat shrinkable sleeve substrate is first stretched twice to ensure that the heat shrinkable sleeve has a good shrinkage rate, and then a unique formula of hot melt adhesive is extruded by a professional reaction vessel and bonded with the back film.The finished product is peeled off.high strength.
