Hot melt adhesive is one of the most environmentally friendly and suitable for high speed automatic assembly line operations. Today's automobile industry is developing rapidly. Especially in China, the sales volume of automobiles in 2013 exceeded 20 million. It has become the world's largest automobile production and sales country. With the improvement of the automatic level of automobile production, the automotive industry needs a large number of rapid bonding, and can adapt to high-speed automated production and environmentally friendly adhesives. Hot melt adhesives can meet all the above requirements, so hot melt adhesives are more and more widely used in the automotive industry. The amount of use has also increased year by year, and it has become an irreplaceable rubber type for the automotive industry.
The bonding materials are extensive, and the automobile is mainly composed of a large number of metal and non-metal parts, and the hot melt adhesive is suitable for the bonding of such products. Such as ABS, PP, PE, felt, etc. used in large quantities in automobiles.
Most hot melt adhesives have examples of use in automobiles, but different types of hot melt adhesives are selected for different parts and applications. According to its function, it can be divided into two types: adhesive type and sealed type. The sealed type mainly uses butyl type glue, which will not be discussed here. If divided according to the use and construction temperature, it can be divided into ordinary type and heat-resistant type. The car is mainly driven outdoors, and generally requires hot-melt adhesive to have certain heat resistance. If classified by material, there are EVA, rubber, APAO, and PUR, PA, PES, etc., which are in the form of blocks, membranes, rods, granules, and powder.
