Adhesive of Pipeline Heat Shrinkable Sleeves

September 01, 2024

Heat-shrinkable materials consist of an external backing made of extruded andcross-linked polyolefin and an internal adhesive made of thermoplastic material. The shrinkage ofthe backing instils a level of circumferential compressionin the coating that supplements the bonding of the sleeve to the pipe surface.

The adhesive have two mainly types:Hot melt adhesive and Mastic

Hot Melt Adhesive:

Precise melt points , preheat temperature is critical

Anchor pattern and surface preparation are critical

Ensure higher preheat temperature dose not broken main lind coatings

Mastic Adhesive:

More forgiving in the field under exterme conditions

Tackiness and pressure sensitive nature of mastic allow for good performance with less than perfect surface preparation

Lot pre-heating temperature

Sichuan forever main products: nuclear radiation, steel pipe repair hot shrink sleeve (belt) series products, straight pipe external anti-corrosion materials, curved pipe composite tape and heat shrinkable winding tape, power cable connection heat shrinkable casing, all kinds of single and double Wall heat shrinkable sleeve, heat shrink sleeve (belt), polyethylene crosslinked composite tape, cable material (PE/PVC), engineering plastics: 3PE modified material, PA/PC/PP/ABS/PS, PA, PC, PBT, POM, PPE, etc., these plastics have high mechanical properties and can be used as engineering materials instead of metal, advanced composite materials for military use, advanced composite materials for military and civilian use.
