Heat Shrinkable Tape Without Epoxy Primer 2PE Coating System 30 m long each roll
Product Description:
Heat shrinkable tape is a special accessory for heat-shrinkable wraparound sleeve PE.
The heat shrinkable tape consists low pre-heated special rubber adhesive and thick-wall irradiated cross linked polyolefin. When heated the backing layer shrinks and the adhesive flows and forms a reliable corrosion protection seal onto metal and adjacent coating surfaces.It installed by wrapping the tape on the pipe joints ,fittings ,bends ,elbows etc .After the shrinking of the tape ,the closure patch should be installed onto the overlap of the tape.
