With the development of lightweight vehicles and the increase in automobile production, the amount of automotive plastics is increasing. The average amount of plastic used per vehicle has grown from 50-60KG in the early 1970s to the current 150KG, and the growth has been Continue. Self-sealing bags China's automotive plastics are generally less than 10% of the car's own weight, and each vehicle's modified plastics are about 100KG ~ 120KG.

In 2012, the national automobile output was 19,217,800 units, a year-on-year increase of 4.6%, of which passenger car production reached nearly 15 million units, an increase of 7% year-on-year, higher than the overall growth rate of automobiles. At present, the application of modified plastic bag factory in automobiles is more. Seen in passenger cars, so the industry's growth tracking passenger car data is more reliable. We conservatively expect domestic car production growth rate to be 7% in 2013, and passenger car growth rate is around 10%.

Assume that the current application of plastics per vehicle is 0.12 tons, based on the output of 15 million passenger cars, the effective market space is nearly 2.4 million tons. If the application ratio is increased and the penetration of commercial vehicles is considered, the market capacity of modified plastics for vehicles will be With more than 6 million tons, the automotive industry is the largest downstream application area for plastics growth in recent years.
