Butyl rubber tape

Butyl rubber tape coating system including Inner tape ,Outer tape ,Joint tape and Primer.

PE anticorrosion tape consists of two layers, butyl adhesive layer and PE basic layer.

Inner layer: Butyl rubber.

Outer layer: PE basic material.

Butyl rubber tape, safe and clean, performs well in insulation, anticorrosion, mechanical strength and anticorrosion, moreover it is of low water absorption, long service life, wide usage and convenient in application. It is extensively used in the pipe work of oil and natural gas transportation, petrochemical industry, electric power, metallurgy, urban natural gas network of pipes, the outside anticorrosion project of the metal pipes involved as well as the outside anticorrosion project of the underground and overhead metallic conduit of the works of petrochemical industry, natural gas and coal transportation.
