Low-temperature hot melt adhesive is currently the most used hot melt adhesive variety. The advantages of this hot melt adhesive are strong adhesion, high film strength, good toughness, can meet the requirements of heat resistance and cold resistance at the same time, good compatibility with other additives, wide range of uses, can adhere to many substrates of different properties, low melt viscosity, easy to apply, and suitable price.


The main component of low-temperature hot melt adhesive, that is, the basic resin is formed by the copolymer of ethylene and vinyl acetate under high pressure, and then combined with a viscosity enhancer, viscosity regulator, antioxidant, etc. to make a hot melt adhesive.EVA hot melt adhesive is a kind of polymer that does not require solvents, does not contain water, and has 100% solid fusibility. It is a solid at room temperature. It is heated and melted to a certain extent to become a liquid adhesive that can flow and has a certain viscosity. After melting, it is a light brown translucent body or white.
