Hot melt adhesive, also known as thermoplastic adhesive, is a substance that is solid at room temperature, melts when heated, and has good viscosity. After hot melt adhesive is applied to the surface of an object, it can be firmly adhered to the object by cooling and solidifying.
There are various types of hot melt adhesives, which can be divided into EVA hot melt adhesive, polyamide hot melt adhesive, polyester hot melt adhesive, and other types based on their raw materials, properties, and application fields. Each type of hot melt adhesive has its unique performance characteristics and is suitable for different adhesive needs.
