2 PE heat shrinkable tape is a special accessory for heat-shrinkable wraparound sleeve PE.
2 PE 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.
2PE Heat shrinkable sleeves have different adhesive , one is hot melt adhesive, another one is mastic adhesive. Both of suitable for pipe operating temperature, 60 ℃,80 ℃ Without primer.
| Hot Melt Adhesive | Mastic Adhesive |
|
Precise melt point,preheat temperature is critical
|
Mastics more forgiving in the field under extreme conditions.
|
|
Anchor pattern and surface preparation are critical
|
Tackiness and pressure sensitive nature of
mastics allow for good performance with less
than perfect surface preparation
|
|
Ensure that higher preheat temperature does not damage main line coating
