Polyethylene Heat Shrink Tubular
I Product Description
Radiation Cross linked Polyethylene Anticorrosion Heat Shrinkable Sleeve (a kind of joint wrap sleeve, used before the pipeline is welded) is on-site joint wrap sleeve, made of three layers, namely the inner layer is binary solvent free epoxy primer, the middle layer is hot-melt adhesive, the outer layer (backing material) is specially modified radiation cross linked PE. The two-layer sleeve bears no primer. The sleeve is specially designed for the on-site joint reparation and bend anticorrosion project of the underground long-distance pipeline and other purpose.

III Property and Advantages
The product is joint less sleeve, with a shrinkage ≥50%. It is mainly used in anticorrosion of the joint of the pipe, the sealing of concentric reducer and valve. The heat shrinkable sleeve has a layer of hot-melt adhesive of super bonding ability ,which can bond with the bottom layer of the pipe and the coating layer of PE,PP, epoxy powder, and epoxy coal pitch to produce effective sealing protection.
1.Great Compatibility to the Pipe Coating
The product is applied to the anticorrosion coating of all types of pipes such as:2PE, 3PE, 3PP, FBE, insulation jacket, coal tar enamel, and petroleum asphalt. It has been used widely in the joint anticorrosion works, the plugging of the big end, and the sealing of the valve on the pipelining site with satisfactory effect, which has been proved in many pipe works.
2.Strong Creep and Aging Resistance
Used together with high quality hot-melt adhesive and primer, the product of our company is able to adapt to different kind of operating temperature , with strong creep resistance and a service life as long as that of the pipe.
3.Outstanding Waterproof Sealing
Composed of hot-melt adhesive of excellent performance, radiation cross linked PE and solventliss epoxy primer, the product has excellent property of anticorrosion, quick contraction, sealing and waterproof.
4. Strong Adaptability on Site
The heat shrinkable sleeve of special structure has a high shrinkage (≥50%), strong shear resistance and peel strength which enables it to be used in the sealing of the joint, concentric reducer, or the plugging of the crossing ends. Because of it performs well in the sealing, it is widely used.
5. Timesaving and Laborsaving Installment
The product is easy and convenient to use, thus it can ensure the quality of the installment. Because the size of the sleeve of special structure changes greatly after it shrunk, compared with that before the shrinking, the installation personnel can observe whether it is properly installed by visual inspection. The productivity is thus greatly promoted because of the quick, easy and convenient installment.
6. Low Preheating Temperature
Adoption of the new material and craft extends the application range of the product in on-site joint anticorrosion. Our company has solvent free epoxy primer of super adaptability which can be applied in coating the joint at the preheating temperature of 55℃-60℃. This enables the product to be used promptly with strong peeling strength, making the operation more convenient.
7. Primer Packaging
In order to make the site operation more convenient, our company has offered matching packaging for the epoxy primer to ensure the quality of the operation.
