Definition and application market of hot melt adhesive and hot melt pressure-sensitive adhesive

Hot melt adhesive is a solid polymer material that remains solid at room temperature but melts into a liquid at high temperatures. This characteristic allows it to quickly cure and form a strong adhesive at lower temperatures. There are various types of hot melt adhesives, including EVA (ethylene vinyl acetate copolymer), SBCs (styrene block copolymer), TPU (thermoplastic polyurethane), etc. Each type of hot melt adhesive has its unique performance characteristics and is suitable for different application fields. The application range of hot melt adhesive is very wide, including packaging industry, label printing, furniture manufacturing, footwear production, automotive assembly and other fields. In the packaging industry, hot melt adhesive is often used for the outer packaging of food packaging, pharmaceutical packaging, and other commodities; In label printing, it is used to fix labels to various surfaces; In the furniture manufacturing industry, hot melt adhesive can be used to assemble wooden components or repair damaged furniture; In the production process of footwear, hot melt adhesive can help to combine the shoe upper with the sole. In addition, hot melt adhesive is often used as a building sealant and waterproof layer material. With the increasing global demand for environmental protection, water-based and biodegradable hot melt adhesives are becoming increasingly popular in the market. These new products not only meet environmental requirements, but also provide excellent performance. In the coming years, it is expected that the hot melt adhesive market will continue to grow, especially in emerging economies and developing countries. Hot Melt Pressure Sensitive Adhesive (HMPSA) is another important type of hot melt adhesive, which typically has good initial adhesion and long-lasting weather resistance. HMPSA is commonly used on the adhesive surface of medical supplies such as bandages, wound dressings, and sanitary products such as diapers and women’s care products. In addition, they are also applied in industrial fields, such as packaging and assembly of electronic components. Due to its solvent-free and high-efficiency characteristics, HMPSA has strong competitiveness in many scenarios that require repeated attachment or disassembly.
