The main components of hot-melt adhesive, i.e. the basic resin is copolymerized with vinyl acetate under high pressure, and then made into hot-melt adhesive with tackifier, viscosity regulator, antioxidant, etc
　　
1. It is usually a solid at room temperature. When heated to a certain degree, it will melt into a liquid. Once cooled below the melting point, it will quickly become a solid again.
　　
2. It has the advantages of fast curing, low pollution and strong adhesion. The adhesive layer has certain flexibility, hardness and toughness;
　　
3. The glue liquid can be applied to the adhesive layer after cooling and curing, and can also be reheated and melted
　　
4. It becomes adhesive again and then adheres with the adherend, which has a certain degree of re adhesion;
　　
5. When using, as long as the hot-melt adhesive is heated and melted into the required liquid state, and applied on the adhered object,
　　
⒍ after pressing, the bonding and curing can be completed in a few seconds, and the degree of hardening, cooling and drying can be achieved in a few minutes.
　　
(5) because the product itself is solid, it is convenient for packaging, transportation and storage;
　　
8. Solvent-free, pollution-free and non-toxic;
　　
⒐ as well as the advantages of simple production process, high added value, high viscosity and strength, high speed, etc., it is favored by people.
　　
(13) hot melt adhesive has stable performance, high utilization rate of raw materials, fast production speed and high yield
　　
(6) advantages of small equipment area and investment
