Viscoelastic Self Adhesive Pipe Coating Wrapping Tape
Basic Info
Model No.: Visco-elastic Tape
Product Description
Visco-Elastic Wrap Tape Description
Visco-Elastic Wrap Tape coating forming process, regardless of the cladding method or winding, binder and
steel pipe surface there is always an air layer, coated to the front of the steel tube surface, must be out of
the air layer, otherwise it will in the air between the steel tube surface and coating membrane, the gas film
under the effect of roller compaction, the sealing process of plastic film cannot be ruled out, in a closed area
along the rolling direction in corrugated flows back and forth, under the effect of water, the formation of
wrinkles, serious when can cause the anti-corrosion layer fracture.
Total tape thickness in mils:1.8mm-2.0mm
Tape width in inches:2"(50mm),4"(100mm),6"(150mm)
Tape roll length in feet:5m,10m,20m
We also production Pvc Insulation Tape,Aluminum Foil Tape,Pp Woven Tape,Pipeline Repair Tape,
Bitumen Tape.
