Product Description

Heat Shrinkable Double-walled Tube


1.Product Introduction 


The Heat Shrinkable Double-walled Tube is one of the Heat Shrinkable Products series, As heat shrink the progress and development of the industry, common heat shrinkable tube has been unable to meet the market need, heat shrinkable tube of products is also on the increase, Double-walled tube is one of them. Normal heat shrinkable tube, and can be referred to as the single wall heat shrinkable tube, double-walled tube with different, Double-walled tube thermal shrinkage tube, and can be referred to as the adhesive heat shrinkable tube, heat shrinkable tube on the production, production of raw materials and hot melt adhesive co-extrusion, thus double-walled tube inner surface with a layer of glue, this is the advantages of Double-walled tube, can not be ignored. It is for this layer of glue, after the encounter heat to melt, adhesion between the quilt cover objects and Double-walled tube, filled with a very good heating process of the cracks, enhance the sealing effect, and therefore, Double-walled tube can be called a waterproof heat shrinkable tube, heat shrinkable tube even in underwater operation, customers also can be at ease use.


Wholesale Heat Shrinkable Double-walled Tube


The outer layer of the Heat Shrinkable Double-walled Tube has the advantages of insulation, corrosion resistance and wear resistance, while the inner layer has the advantages of low melting point, waterproof, sealing and high adhesion. Double-walled tube is widely used in electronic equipment wiring waterproof, air leakage prevention; Wire branch anti-corrosion protection, wire and cable repair, water pump and submersible pump wiring waterproof and other occasions.

5.Product Qualification 


The production of heat-shrinkable cable accessories needs to go through a series of processes such as Mixing → Forming → Irradiation → Expansion → Gluing. Shape memory effect of polymer materials is the basic principle of fabricating heat-shrinkable materials. The characteristics of the polymer material itself give the heat shrinkable cable accessories with good electrical and mechanical properties, light weight, easy installation and other advantages. The product is waterproof, stress control, shielding, insulation in one, can be used in a variety of harsh environmental conditions for a long time. Widely used in Electric Power Industry, Petroleum Industry, Chemical Industry, Metallurgy, Railway, Port, Construction and other fields.
