Polyethylene backing with bituminous adhesive wrap tape

System description:

XUNDA-T600 Bituminous anticorrosion tape series is designed for corrosion protection of straight pipes, fittings, flanges valves, bends, elbows, carbon steel pipes and other irregular configurations, also be called joint wrap tape.
XUNDA-T600 Bituminous tape be made of a stabilized polyethylene carrier film, coated on one sides with a permanently plastic synthetic compound on bitumen base.
Bituminous anti corrosion tape

Structure

The specification of the tape consists of three layers,
Adhesive: Butyl rubber Bituminous Compound and Adhesion Promoting Resins
Film backing: Special blend of stabilized Polyethylene
Interleaf: Anti-adhesive Film Treated with Silicone （release paper）

Features:

● Heavy duty butyl bitumen compound adhesive
Excellent adhesion to pipe and self
● Flexibility provides extra protection at vulnerable areas
Excellent conformability and consistent uniform thickness
● Easily applied with no special equipment
Compatible with common pipe coatings
● Excellent resistance to cathodic disbonding
Resistant to UV and water proof.
●Can be applied over a wide temperature range
Good conformability and consistent uniform thickness
