Rubber containing heat shrinkable tube

Release date:2021-10-13 author:admin Click:

   Glue containing heat shrinkable pipe is actually a kind of product developed on the basis of ordinary PE heat shrinkable pipe. It is divided into internal and external double-layer structure. The outer layer is made of polyethylene and other materials, and the inner layer is made of hot-melt glue through composite processing. Consistent with the ordinary heat shrinkable tube, the product needs to be irradiated by electron accelerator after completing the extrusion process, that is, the irradiation process to make it have shrinkage effect; The final product has excellent outer insulation and good wear resistance; When the inner layer is heated, the glue melts and adheres to the inner wall, with remarkable waterproof and sealing effect.

Heat shrinkable tubes containing rubber are also widely used in products, which can be confirmed in the previous sales process. The product has strong applicability. Like ordinary heat shrinkable tubes, it can be used in all walks of life. Compared with ordinary heat shrinkable tubes, most customers who choose heat shrinkable tubes with glue because they have glue inside are considering their sealing effect. Relatively speaking, heat shrinkable tubes with glue are more used in military industry, shipping, communication, machinery and other fields.
Compared with ordinary heat shrinkable tubes, rubber containing heat shrinkable tubes mainly have the following differences:

1) There is a difference in the shrinkage ratio between the two. The heat shrinkable tube containing glue has a higher product shrinkage ratio, usually 3:1 and 4:1. The utilization rate of the former is higher; The shrinkage ratio of ordinary heat shrinkable tube is 2:1, that is, we often say twice the shrinkage;

2) There are differences in wall thickness between the two. On the premise of similar specifications, the thickness of rubber containing heat shrinkable pipe will be thicker;

3) The heat shrinkable tube containing glue is a double-layer structure, that is, we often say double wall tube; Ordinary heat shrinkable tube is a single-layer structure, also known as single wall heat shrinkable tube;

4) During the production of glue containing heat shrinkable pipe, the raw materials and hot melt adhesive are coextruded to achieve better sealing effect. It is widely used in areas with waterproof requirements such as ships and water tanks, while ordinary heat shrinkable pipe is more inclined to be used in insulation protection and power departments in daily life.
