Product Details
Polyethylene film is thermally compounded and co-extruded with a butyl adhesive layer to create polyethylene joint repair tape, a corrosion-resistant material. It possesses exceptional anti-corrosion properties, great mechanical strength, impact resistance, and superior insulation. It also has a long working life, a wide range of applications, a simple structure, and good aging resistance and low water absorption.
This repair tape features a consistent thickness of adhesive and a dependable sealing and bonding action. During storage and field use, the base material and adhesive layer form a strong bind without separating. It possesses great UV resistance, aging stability, and good heat resistance. It is appropriate for both machine winding and manual wrapping because to its strong tensile strength and appropriate elongation.
It is extensively utilized in engineering projects related to the coal, petroleum, natural gas, petrochemical, and water supply industries.
