Material Selection For Automotive Interior Parts


At present, Automotive Interior parts have been widely used in the automotive industry.

 

  At present, Automotive Interior parts have been widely used in the automotive industry. The application of plastics in automobiles is mainly divided into three categories: exterior parts, interior parts and functional structural parts.
 
Plastic exterior parts reduce the quality of the car and achieve energy-saving purposes, such as front and rear protection, fenders and door exterior panels; plastic interior parts are safe, environmentally friendly, and comfortable, and can absorb impact energy and vibration energy. Elastomers and foamed plastics are used in the manufacture of dashboards, seats, headrests and other products, which can reduce damage to the vehicle and protect the human body during collisions, and improve the safety factor of the vehicle. The functional structural parts are mostly high-strength engineering plastics. Reduce quality, reduce costs, simplify processes, such as plastic fuel tanks, some parts on the engine and chassis. At present, the varieties of automotive plastics include: polypropylene, polyurethane, polyvinyl chloride, thermosetting composite materials, ABS, polyamide, polycarbonate, polyoxymethylene, polyphenylene ether, polymethyl methacrylate and polyethylene, etc. Generally used It is their modified PP materials and composite materials.
 
  PP (polypropylene) material
Plastic parts of car center console has been widely used in various automobile assembly systems due to its wide range of sources, low density, good mechanical balance, chemical resistance, easy processing, and low price. However, general-purpose PP materials have disadvantages such as large shrinkage, poor product dimensional stability, and easy warping and deformation; low temperature brittle fracture, poor low temperature toughness; poor light aging resistance and heat aging resistance. Can not meet the special requirements of automobile bumpers, hair covers, fenders and front door skirts, etc. General PP materials need to be modified.
