Hot melt adhesive is the most environmentally friendly and suitable for high-speed automatic assembly line operation. Nowadays, the automobile industry is developing rapidly, especially in China. With the improvement of the automation level of automobile production, the automobile industry needs a large number of adhesives that can be quickly bonded, adapt to high-speed automated production and are environmentally friendly. Hot melt adhesives can just meet all the above requirements, so hot melt adhesives are more and more widely used in the automobile industry, and their usage is increasing year by year, which has become an irreplaceable adhesive in the automobile industry. The reason why there is such a trend is determined by the characteristics of hot melt adhesive itself.

Hot melt adhesive features:

1, the curing speed is fast, and it is suitable for modern high-speed assembly line operation.

2. There are a wide range of bonding materials, and automobiles are mainly composed of a large number of metal and nonmetal parts. Hot melt adhesives are just suitable for bonding such products. Such as ABS, PP, PE, felt and so on, which are widely used in automobiles.

3. The construction is convenient. Hot melt adhesive can be applied in many ways, such as spraying, roller coating, scraping and so on.

4. Hot melt adhesive is 100% solid content, which is convenient to store, energy-saving, environmentally friendly, non-toxic and will not cause secondary pollution to the environment.

5. Nowadays, the world is short of resources, and many auto companies have considered recycling the resources after scrapping their cars when producing them. Hot melt adhesive has the characteristics of melting when heated, and it has more advantages when recycling and disassembling cars.

Types of hot melt adhesives for automobiles:

Most hot melt adhesives are used in automobiles, but different parts and uses will choose different kinds of hot melt adhesives. According to its function, it can be divided into two categories: adhesive type and sealing type. The sealing type mainly uses butyl glue, which is not discussed here. According to the purpose and construction temperature, it can be divided into ordinary type and heat-resistant type. Cars are mainly driven outdoors, and hot melt adhesives are generally required to have certain heat-resistant performance. According to the classification of materials, there are EVA, rubber, APAO, PUR, PA, PES, etc., and the shapes are block, film, rod, particle and powder.
