From the current development trend, the world's adhesive industry is developing in the direction of energy saving, pollution-free, low-cost and high performance, and solvent-free environmentally friendly adhesives have become the mainstream of the current adhesive industry development. Hot melt adhesive is a kind of solventless solid adhesive based on thermoplastic polymer (resin, rubber). It is an environmentally friendly adhesive with rapid bonding, wide application, non-toxic and pollution-free. Hot melt adhesive conforms to the needs of The Times and is a direction of the development of adhesives in today's world.
Hot melt adhesive is a plastic adhesive, its chemical properties are stable, the physical state will change with the temperature within a certain temperature range, and it will show a solid state at room temperature. Hot melt adhesive production process is simple, with the following main characteristics of heat:
1) Fast bonding: usually only a few seconds to tens of seconds, shorten the process, suitable for assembly line operation, high labor productivity.
2) Wide range of applications: for many materials (such as fabric, leather, wood, plastic, metal, etc.) have high adhesion.
3) 100% solid, solvent-free, non-toxic, pollution-free, in line with environmental requirements, and easy to transport and store.
4) It has significant social and economic benefits.
Therefore, hot melt adhesive is an environmentally friendly adhesive with excellent performance, high safety and reliability, and is gradually replacing traditional solvent adhesives, and the downstream application range is constantly expanding. In fact, China's hot melt adhesive industry ushered in a breakthrough after entering the 21st century, and began to enter a stage of rapid growth after early market accumulation and technology precipitation. As a major type of adhesive, hot melt adhesives have been greatly developed in China, and China has become one of the main production bases of hot melt adhesives in the world. Therefore, the application field of hot melt adhesive products has been very wide.
1. automotive industry China's hot melt adhesive industry will be the fastest growing industry in the automotive industry. Automotive manufacturing uses hot melt adhesives in a wide range of applications. Its use in automobiles is particularly attractive because of the many advantages of hot melt performance. Common applications in cars include: car lights, seats, ceilings and other parts.
2. Packaging industry: As the main market for hot melt adhesives, the packaging industry, hot melt adhesives will continue to expand and grow with packers.
3. Label industry: With the rapid development of e-commerce, logistics transportation, product packaging, goods identification and other industries have also grown significantly, and the label industry driven by these industries, as well as the adhesive industry for labeling, has also developed rapidly. Hot melt adhesive is an important type of label adhesive, because the product itself is solid, easy to package, transport, storage, and simple production process, high added value, high bonding strength, fast, and has the advantages of solvent-free, non-polluting, non-toxic and tasteless, green and environmental protection. In this market, the application market of hot melt products will continue to increase.
4. Hygiene products Industry: The global market for baby diapers, adult incontinence and feminine hygiene products is increasingly prompting governments to develop stringent disposal regulations and laws. Hot melt adhesives eliminate many handling problems for manufacturers. Most people are still very optimistic about the use of hot melt adhesives in the industrial sector in the future and beyond.
5. Furniture: used for wood, furniture to fit wood edges, PVC, etc.;
6. Shoe making: leather shoes styling, toe toe toe upper lining, folding, insole, shoe material composite, etc.;
7. Electronics, aerospace, military, solar cell packaging materials, electronic products, etc.
With the acceleration of China's economic growth, the downstream application field of hot melt adhesive continues to expand, the market demand is increasing rapidly, and the industry has entered a stage of rapid development, and the number of production enterprises is increasing. At this stage, China's hot melt adhesive industry in the production equipment, technology, product quality and other aspects have reached the international advanced level, can supply a complete range of products, and more cost-effective, basically can meet the domestic market demand.
