Hot melt adhesive is a kind of plastic adhesive. In a certain temperature range, its physical state changes with the change of temperature, but its chemical characteristics remain unchanged. Non-toxic and tasteless, belonging to environmental protection chemical products. The product is convenient for packaging, transportation and storage, solvent-free, pollution-free, with the characteristics of simple production process, high added value and high bonding strength, which is deeply loved by consumers.

Introduction of hot melt adhesive

Hot melt adhesive consists of basic resin, tackifier, viscosity regulator and antioxidant. It is a solid at room temperature. When heated and melted to a certain temperature, it becomes a liquid with a certain viscosity. After melting, the hot melt adhesive is light brown or white.

The basic resin of hot melt adhesive is the polymerization of ethylene and vinyl acetate at high temperature and high pressure, which is mainly used in the production of shoes and hats. Clothes using this adhesive not only have a crisp and plump appearance quality, but also have the characteristics of natural smoothness after washing, and can be worn without ironing.

The working time of hot melt adhesive is generally around 15 seconds. With the wide application of modern production lines, the working hours of hot melt adhesives are getting shorter and shorter. For example, the working time of hot melt adhesive in book binding and speaker manufacturing is about 5 seconds.
