CNP 3LPP wrap-around heat shrink sleeve
Product Profile
CNP 3LPP system is a wrap-around heat shrink sleeve which replicates the structure and the performance of factory applied three-layer PP coatings. It is polypropylene based heat shrink sleeve ,operating temperature up to 110°C-140°C.
Construction
First layer: Liquid epoxy, solvent-free two-component.
Second layer: High shear strength polypropylene adhesive layer.
Third layer: Radiation cross-linked, high density polypropylene.
Features & Benefits
● CNP 3LPP allows 3 layer PP coatings have a virtually monolithic coating.
●Cross-linked PP backing made sleeve suited for higher stress conditions caused both by elevated temperatures and by soils with contraction between wet-dry cycles.
● High performance PP adhesive provides excellent resistance to Cathodic Disbondment to against abrasion and chemical cracking at elevated temperature.
