Hot melt adhesive (English Name: hot glue) is a kind of plastic adhesive. Its physical state changes with the change of temperature in a certain temperature range, but its chemical characteristics remain unchanged. It is non-toxic and tasteless, and belongs to environmental protection chemical products. Its products are solid, easy to package, transport, storage, solvent-free, pollution-free, non-toxic; as well as simple production process, high added value, high bonding strength, fast speed and other advantages.

   Product selection

1、 The color requirements of glue should be different. If there is no special color requirement for the adherent, yellow hot melt adhesive is recommended. Generally speaking, yellow hot melt adhesive is better than white hot melt adhesive.

2、 Surface treatment of the adherent. The surface treatment of hot melt adhesive is not as strict as other adhesives, but the dust and oil on the surface of the adherent should also be properly treated to make the hot melt adhesive play a better bonding role.

3、 Operation time. Fast operation is a major feature of hot melt adhesive. The operation time of hot melt adhesive is generally about 15 seconds. With the wide application of modern production mode assembly line, the operation time of hot melt adhesive is required to be shorter and shorter, such as book binding and speaker manufacturing. The operation time of hot melt adhesive is about 5 seconds.

4、 Temperature resistance. Hot melt adhesive is sensitive to temperature. When the temperature reaches a certain degree, the hot melt adhesive begins to soften. If it is lower than a certain temperature, the hot melt adhesive will become brittle. Therefore, the selection of hot melt adhesive must fully consider the temperature change of the product environment.

5、 Sticky. Hot melt adhesive viscosity is divided into early viscosity and late viscosity. Only the early viscosity and later viscosity are consistent can the hot melt adhesive keep stable with the adherent. In the production process of hot melt adhesive, it should be guaranteed that it has anti oxygen, anti halogen, acid and alkali resistance and plasticization. Due to different materials, the viscosity of hot-melt adhesive is also different. Therefore, different hot-melt adhesives should be selected according to different materials.

Usage

       When it comes to the application of hot-melt adhesive machine in various industries, the development of our related industries has been pushed to an advanced stage, and the production capacity and related operator configuration have also changed. So this benefits from the convenience brought to us by the development of science and technology. But how many people know the ingredients of relevant consumables? Hot melt glue stick is the most commonly used one. What are the components of hot melt glue stick?

       Nowadays, hot-melt adhesive stick has the advantages of high strength, aging resistance, non-toxic and good thermal stability. It can be used in wood, plastic, fiber, fabric, metal, furniture, lampshade, leather, handicrafts, toys, electronics, electrical components, paper products, ceramics, pearl cotton packaging, etc. it can be widely used in factories and families.

       The hot melt adhesive stick is white and opaque (strong type), no poison, easy operation, continuous use, no carbonization phenomenon. It has the characteristics of fast adhesion, high strength, aging resistance, no poison, good thermal stability and film toughness. The shapes are rod and granular. Low temperature resistant hot melt adhesive is suitable for hot melt adhesive gun and machine, used for bonding wood, paper products, fiber products, leather, metal, plastic, especially for export and high cold area and low temperature area. It has good adhesion, does not open glue and does not crack. It is a high-grade hot melt adhesive product, non-toxic and in line with environmental protection requirements. Medium hardness, good toughness, medium fluidity, strong adhesion and easy operation
