Adhesives for automotive applications are the most environmentally friendly and suitable hot melt glue types for high-speed automatic assembly line operations. Today's automobile industry is developing rapidly. With the improvement of the auto production level, the automobile industry needs a large number of fast types of automotive adhesives and can adapt to high-speed automated production and environmentally friendly adhesives. Hot melt adhesive glue can meet all the above requirements, so hot melt adhesives are used in automobiles. Adhesives used in automotive industry are becoming more and more widespread, and the amount of use is increasing year by year, and it has become an irreplaceable type of rubber in the automotive industry. The reason for this trend is determined by the characteristics of the hot melt adhesive itself.
Automotive adhesive solutions including hot glue on felt, carheadlamp adhesive, automotive mirror adhesive and automotive carpet adhesive. The following are main types of adhesive used in the automotive industry.
Seat Assmbly Glue
Ceilling Assmbly Glue
Felt Glue
Car Headlamp Glue
Car Mirror Glue
Carpet Assmbly Glue in Car Truck
Battery Assmbly Glue
Low VOC Glue
The reason for this trend is determined by the characteristics of the adhesives used in automotive industry.
1. Fast curing speed, suitable for modern high-speed assembly-line operation.
2. There is a wide range of bonding materials. Automobiles are mainly composed of a large number of metal and non-metal parts. Hot melt adhesives are suitable for bonding such products. Such as ABS, PP, PE, hot glue felt to fabric, etc. which are widely used in automobiles.
3. Convenient construction, 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, convenient to store, energy-saving, environmentally friendly, non-toxic, and will not cause secondary pollution to the environment.
5. Nowadays, the world's resources are tight. Many automobile companies have considered recycling resources after scrapped cars when producing cars. Hot melt adhesives for automotive applications are better than other types of automotive adhesives which have the characteristics of heating and melting, which is more advantageous in car recycling and dismantling.
Most hot melt adhesives have been used in automobiles, but different parts and uses will choose different types of hot melt adhesives. According to the purpose and construction temperature, it can be divided into ordinary type and heat-resistant type. Automobiles are mainly driven outdoors, and hot melt adhesives are generally required to have certain heat resistance. The temperature resistance of many products of our company can reach above 90℃. If classified by material, there are EVA based hot melt adhesive, rubber, APAO, PUR, PA, PES, etc., and the shapes include block, film, rod, granule and powder.
Body and Chassis
Structural Bonding: Adhesives can be used to bond structural components like roof panels, doors, and hoods, reducing weight and improving vehicle rigidity.
Sealing: Sealing gaps and joints between body panels helps prevent water ingress and noise.
Sound Deadening: Adhesives can be used to dampen vibrations and reduce noise levels within the vehicle.
Interior
Trim and Upholstery: Adhesives are used to attach interior trim pieces, dashboards, and upholstery to the vehicle's frame.
Soundproofing: They can be applied to dampen vibrations and reduce noise transmission.
Gasketing: Adhesives seal gaps between components to prevent water ingress and dust accumulation.
Electrical and Electronic Components
Component Mounting: Adhesives are used to mount electronic components like sensors, actuators, and control modules to the vehicle's structure.
Wire Harnessing: They can be used to secure wire harnesses and connectors.
Sealing: Adhesives seal electronic components to protect them from moisture and contaminants.
Engine and Drivetrain
Gasketing: Adhesives can be used to seal engine blocks, cylinder heads, and transmission housings.
Sound Deadening: They can be applied to reduce noise and vibration from the engine and drivetrain.
