RSYB(S) Heat Shrinkable Tube

RSYB(S) Heat Shrinkable Tube
Product Detailed
RSYB(S) heat shrinkable tube replicates the structure and performance of mill-applied three-layer PE coatings.

RSYB(S)

Heat Shrinkable Tube

Girth weld protection system for three-layer coated pipes

1.       Description

Construction: Three-layer system

First layer: Liquid epoxy, solvent-free two-component

Second layer: High shear strength copolymer adhesive

Third layer: Radiation cross-linked polyethylene

The RSYB(S) series is a tublar heat shrinkable sleeve which replicates the structure and performance of mill-applied three-layer PE coatings. RSYB(S) series also has excellent compatibility and has been extensively used on many other mill-applied coatings.
