XUNDA-T-300 Pipe Joint wrap tape
Tape Coating for Pipeline Joints & Fittings&special piping
Product System description:
polyken 930-50 930-35 Joint wrap tape tape series is designed for
corrosion protection of straight pipes, fittings, flanges valves,
bends, elbows, carbon steel pipes and other irregular
configurations.T300 wrap tape be made of a stabilized Polyethylene
carrier film, coated on one sides with a permanently plastic
synthetic compound on Butyl rubber compound base.The unique
adhesive retains conformability over a wide temperature range, yet
exhibits an elevated level of shear resistance, which is a key
in-ground performance characteristic.
Product Structure
The specification of the tape consists of three layers,
Adhesive: Butyl rubber Compound Bituminous Adhesion Promoting
Resins
Film backing: Special blend of stabilized Polyethylene
Interleaf: Anti-adhesive Film Treated with Silicone (release paper)
