Modified plastics indicates that adding small molecular organic or inorganic material in the polymer, by physical or chemical action, thus giving its machining performance or make some performance improvement, so that the plastic has become a distinct characteristic. The change of plastic is in the automotive and appliance brought a wide range of application domains, and modified plastics contain great potential for development.

With the 2009 car industry of plastic rapid demand, China's plastics industry and the automotive industry has formed "a prospering harmed". While the target to the modified plastics. The use of lighter, stronger and better auto parts to relieve some of the downturn in the auto industry. As is known to all, modified plastics is the most important automotive lightweight materials, modified plastics can not only parts of about 40% of the weight loss and modified plastics can also make the purchasing cost can be reduced about 40%.

Therefore, in recent years in the car changed the rapid rise in the amount of plastic. Has been basically achieved plastic, "plastic steel" for the development of the automobile is leading the change of plastics in the automotive applications toward the broader field of continuous innovation.
