What is  hot melt adhesive

Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. Because the product itself is solid, it is convenient for packaging, transportation, storage, solvent-free, non-polluting, non-toxic; and it has the advantages of simple production process, high added value, strong bonding strength, and fast speed.

Product Selection for Hot Melt Adhesives

1. The color requirements of glue should be different. If the object itself has no special requirements on the color, it is recommended to use yellow hot melt adhesive. Generally speaking, yellow hot melt adhesive is more viscous than white.

Second, the surface treatment of the adhered object. Hot-melt adhesives are not as strict as other adhesives in the surface treatment of the bonded object, but the dust and oil on the surface of the bonded object should also be properly treated in order to make the hot-melt adhesive play a better role in bonding.

3. Working hours. Fast operation is a major feature of hot melt adhesives. The working time of hot-melt adhesive is generally about 15 seconds. With the wide application of modern production methods--assembly lines, the working time of hot-melt adhesive is getting shorter and shorter, such as the working time of hot-melt adhesive in bookbinding and speaker manufacturing. It is required to reach about 5 seconds. Four, temperature resistance. Hot melt adhesives are sensitive to temperature. When the temperature reaches a certain level, the hot melt adhesive begins to soften, and below a certain temperature, the hot melt adhesive will become brittle, so the choice of hot melt adhesive must fully consider the temperature change of the product's environment. Five, stickiness. The viscosity of hot melt adhesive is divided into early viscosity and late viscosity. Only when the early viscosity is consistent with the late viscosity can the hot melt adhesive and the adhered object remain stable. In the production process of hot melt adhesive, it should be ensured that it has anti-oxidation, anti-halogen, anti-acid and alkali resistance and plasticizing properties. The viscosity of the hot melt adhesive is also different depending on the material of the adhered object. Therefore, different hot melt adhesives should be selected according to different materials. Use of hot melt adhesive

When it comes to the application of hot melt adhesive machines in various industries, the development of our related industries has 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 technology today. But how many people know what are the ingredients of related consumables? The most commonly used ones are hot melt glue sticks. What are the ingredients of hot melt glue sticks?

Today's hot melt glue sticks have the advantages of high strength, aging resistance, non-toxicity, and good thermal stability. They can be used in wood, plastic, fiber, fabric, metal, furniture, lampshades, leather, handicrafts, toys, electronics, electrical components, paper Products, ceramics, pearl cotton packaging and other mutually sticky solids can be widely used in factories and households.

The hot melt glue stick is white and opaque (strong type), non-toxic, easy to operate, and has no carbonization phenomenon in continuous use. It has the characteristics of fast bonding, high strength, aging resistance, non-toxic, good thermal stability, and film toughness. The shapes are stick and granular. Low-temperature resistant hot-melt adhesive is suitable for hot-melt glue guns and machines, used for bonding wood, paper products, fiber products, leather, metal, plastics, especially suitable for export and high-cold areas, low-temperature areas, good viscosity, not open It is a high-grade hot-melt adhesive product, which is non-toxic and meets environmental protection requirements. Medium hardness, good toughness, medium fluidity, strong adhesion, easy to operate.
