Automotive non-metallic materials are widely used in automotive interiors, exteriors, chassis and other parts systems. While reducing the weight of the vehicle, they also play the role of energy absorption, buffering, heat insulation and sound insulation, and have very good use effects. However, due to the characteristics of non-metallic materials, small organic molecules such as benzene, toluene, formaldehyde, and acetaldehyde are released into the cab of the car in the use of car interiors, which endangers human health and produces a great irritating odor inside the car. Therefore, it is of great significance to develop environmentally friendly and low-emission non-metallic materials for automotive interiors.
The polymer foam material is a microporous material composed of numerous pores on the basis of polymer resin. It is widely used in automobiles due to its advantages of light weight, good heat insulation and good cushioning. The foam materials currently used in automotive interiors are mainly polyurethane foam (PUR) and polyolefin foam. However, during long-term use, PUR foam will continue to release unreacted isocyanates, benzenes, aldehydes and other small molecular harmful substances, which will affect the air quality in the car.
Polypropylene foam is a closed-cell foam obtained by using high melt strength polypropylene (HMSPP) as the resin matrix and foamed by physical gas. It has excellent mechanical properties, good heat resistance, wide range of foaming ratio and adjustable density. , non-toxic and tasteless, 100% EPP is a pure hydrocarbon that is completely free of additives such as plasticizers and foaming agents, so it is considered to realize the lightweight and improvement of automobiles.
Is there any difference between EPP car interior parts and regular car interior parts? No different. EPP car interior only refers to decorative small parts such as door trim panels, armrests, instrument panel assemblies, compartment partitions, seat mats, etc. All aspects of the interior of the car, such as car sunscreen, car handgloves, car floor mats, car anti-skid pads, seat cushions, etc. are all car interior products. The most simple and brilliant thing about the car design is the interior design. The appearance of the car is for others to see, and what people really enjoy is the interior design of the car. From the point of view of styling planning, interior planning accounts for more than half of the entire vehicle planning. Because compared to the appearance, the components involved in interior planning are relatively complex. Judging from the development trend in recent years, the international trend of interior design is more and more digital and high-tech, and the modeling tends to be concise and neat, and more attention is paid to the use and deployment of various raw materials.
What are needed to produce epp auto parts?
Main machinery like EPP pressurizing system and epp shape molding machine with necessary mold as the picture shows.
