PVC Pipe Wrapping Tape
PVC anticorrosive tape is “All Weather ” pipe protection tape. The tape is composed of PVC plastic backing and high adhesion synthetic rubber adhesive. The adhesive layer is composed of butyl rubber(BR) or butyl rubber base modified bitumen compound(BC). The PVC plastic backing has excellent electrical insulation and chemical resistance. The synthetic adhesive has excellent anti-aging, seal ability effect. So it is always used for corrosion protection for metal piping systems above and below ground.
PVC anticorrosive tape is easy to apply with no special tools or equipment. Being highly flexible, it is suitable for work in low temperature and for work on joint part or flexural area. It provides positive protection against abrasion and corrosive action for steel pipe, fittings or electrical conduit systems.
