EVA hot melt adhesive film is one of the common types of hot melt adhesive film. EVA hot melt adhesive film is a hot melt adhesive film product made of EVA as the main raw material. EVA is a commonly used resin material, and its chemical name is ethylene-vinyl acetate copolymer. EVA hot-melt adhesive films are usually colorless, transparent or foggy.
1. Method for manufacturing EVA hot melt adhesive film
According to the composition of the hot melt adhesive, EVA hot melt adhesive film uses EVA as the basic polymer, and additives such as thickeners, viscosity regulators, and antioxidants are added to make hot melt adhesive particles. The obtained hot-melt adhesive particles are then melted through a coater or casting machine to form a hot melt adhesive film. In EVA hot melt adhesive film, the EVA content often reaches 60%-90%, so it is called EVA hot melt adhesive film.
2. According to the shape and method of use of EVA hot melt adhesive film
EVA hot-melt adhesive particles are produced by a coating machine into a paper-coated hot-melt adhesive film, which is formed without a substrate through a casting machine. Substrate-free hot melt adhesive film is also known as a bare film. These are the two conventional forms of EVA hot melt adhesive film. Hot melt adhesives are solvent-free, water-free, and solid-soluble polymers. They are solid at room temperature, and melt when heated into liquid adhesives that can flow and have a certain degree of viscosity. After cooling, they can re-solidify to form adhesion between materials. EVA hot melt adhesive film is laminated using a pressing machine or roller laminating machine.
3. In what fields is EVA hot melt adhesive film used
Since hot melt adhesive film has the characteristics of fast curing, low pollution, and strong adhesion, it is an environmentally friendly and efficient industrial adhesive. EVA hot melt adhesive film is one type that is used the most in hot melt adhesive film. It is widely used in footwear industry, automobile industry, wall cloth manufacturing and other industries. Since EVA hot melt adhesive film has a wide range of adhesion, it has good adhesion to many materials and plays a very important role in the development of new materials.
