Double wall heat shrinkable tube with glue

The double wall heat shrinkable pipe with glue is to add a layer of hot-melt adhesive on the inner side of the heat shrinkable pipe. The main component of the hot-melt adhesive is that the basic resin is processed by ethylene and vinyl acetate under high pressure, and then mixed with tackifier, viscosity regulator and antioxidant to make the hot-melt adhesive. It is widely used in the fields of cable, welding materials, power insulation protection materials, and anti-corrosion and anti-corrosion of metal pipelines. How to play its role in the use of double wall heat shrinkable tubes with glue? What are the characteristics? Let's give a brief introduction.

Double wall heat shrinkable tube with glue

First of all, the double wall heat shrinkable tube with glue usually exists in the form of solid under the normal indoor temperature conditions. It will dissolve into liquid during the external heating process. Once the temperature is lowered and cooled to below the melting point, it will form solid again. During the use of the double wall heat shrinkable tube with glue, as long as the hot melt adhesive is heated and melted into liquid, and coated on the adherend, the bonding and curing can be completed in a short time after being pressed by external force, After a period of time, it can reach the degree of cooling, drying and hardening. The double wall heat shrinkable pipe with glue has re viscosity. The glue liquid of the heat shrinkable pipe can be applied to the adhesive layer after cooling and curing on the adherend. It can also be reheated and melted to become an adhesive body and then bonded with the adherend, with certain re viscosity;

Secondly, the double wall heat shrinkable pipe with glue has the characteristics of fast curing, low pollution and strong adhesion. In addition, due to the special internal material composition, it also has the characteristics of flexibility and hardness. Moreover, the double wall heat shrinkable pipe with glue has the advantage of sealing, can resist the bad external environment, and plays the role of anti-corrosion and rust prevention.
