Problems solved by technology

[0002] As the main component of automobile interior, the VOC volatilization of plastic directly affects the VOC of the whole vehicle. In order to comply with the development trend of environmental protection, green, low toxicity and low harm of new energy automobile interior, new environmentally friendly plastic materials can be used for automobile interior In recent years, it has received extensive attention from the industry. Polyvinyl chloride, polypropylene, polyoxymethylene, polycarbonate, and acrylonitrile-butadiene-styrene terpolymer are all commonly used plastic materials for automotive interiors. The release agents, flame retardants, and plasticizers used in the process often lead to a large amount of harmful substances such as benzene and toluene, which obviously cannot meet the needs of new energy vehicle interiors
