RSYB(S) Heat Shrinkable Tube

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. 2.
