Hot melt adhesive film is a film product with or without release paper, including EVA hot melt adhesive film, PO hot melt adhesive film, PES hot melt adhesive film, TPU hot melt adhesive film, PA hot melt adhesive film, etc. Hot melt adhesive film can apply to metal, plastic, paper, wood, ceramics, textiles and other materials, and can also get good results on uneven surfaces; mainly used for nameplates, plastics, hardware Bonding of parts, bonding and fixing of metal casings of electronic products, bonding and fixing of reinforcing plates, lamination and bonding of smart cards and chip passports, bonding of mobile phone window frames and front covers, bonding of camera battery slots, etc.

Let me introduce to you the application of hot melt adhesive film in the automotive industry:

With the rapid development of China’s automobile industry, the popularity of family cars has become higher and higher in recent years, especially domestic automobiles have maintained a strong development momentum and become the hope of revitalizing the national industry. In the manufacturing process of automobiles, it involves the bonding of a large number of different materials, which requires adhesive products to help. Hot melt adhesive film is an adhesive product used in the automotive industry.

In the automotive industry, there are many materials that need to be bonded, such as aluminum in metal materials, ABS, PP, PE in plastics, as well as cloth, felt, leather, rubber, etc. Each of their materials has different characteristics and different bonding requirements. Hot melt adhesive film is a kind of hot melt adhesive. Because it is a thermoplastic adhesive product, due to this limitation, it is generally not used for structural bonding, but only used for non-structural bonding applications. . Therefore, hot melt adhesive films are widely used in automotive interiors, such as the lamination of car ceilings, car seats, car floor mats and other parts. It can be said that the application of hot melt adhesive film in these similar fields involving large-area lamination is relatively mature, but although there have been attempts in the bonding of other parts of the car, it is not yet fully mature for the entire industry.

Because the car is a very small space, and this space has a very good airtightness. With the increasing dependence of people on the car, the time spent in the car is getting longer and longer, and the environmental protection issue of the car has received increasing attention and attention. Therefore, the automotive industry generally pays attention to the air environment in the car There are very high testing requirements.

To say that the biggest impact on the air environment in the car is the automotive interior materials, especially the selection of interior material adhesive products has a huge impact on VOCs emissions. It is necessary to use environmentally friendly adhesives without VOCs emissions. Avoid material pollution to the air in the car, thereby affecting the health of passengers in the car. As a result, those strong solvent-based adhesives in the past lost their usefulness at once due to the problem of solvent volatilization, and were replaced by hot melt adhesive products. In addition, it is worth mentioning that the automotive industry is an industry that requires a particularly high degree of automation and needs to be considered in all processes. The high efficiency, cleanliness and environmental protection of the hot melt adhesive film are in line with its requirements for the process. Although hot melt adhesive film is not the only adhesive product that can be used in automobiles, compared with other types of adhesives, it is indeed a very promising adhesive product, which is worthy of attention.
