Polyethylene Insulation Film Wrapping Tape Black Color And White Color

1)The inner and outer layers of tape have polyethylene (PE) backings with butyl rubber based adhesives. The PE backing is formulated differently for the inner layer and outer layer due to the different properties that are desired. 

2)The inner layer mostly consists of low density PE which allows it to be conformable to the pipe surface. The outer layer has more high density PE to allow the tape to be conformable, but also provide protection to the inner layer from damage during storage, transportation, installation and throughout the lifetime of the pipeline. 

Application of Polyethylene mechanical protective coating tapes:

    3) Prepare surfaces by removing all loose scale, rust or other foreign matter by grit blasting or wire brush. Surface must be clean, dry and free of grease. Apply thin film of Butyl Primer to all surfaces to be wrapped and allow to dry. Peel back interleaving and apply adhesive side of the tape to the surface and press down. Apply the tape spirally with enough tension to make it conform. Remove interleaving as wrapping proceeds. Overlap each turn by at least 1" or 55% to achieve double thickness.
