With the development of modification technology,
modified plastics have gradually developed from the initial interior parts to exterior parts and engine peripheral parts due to their obvious advantages of low cost and high performance. As of 2012, Applications in the automotive sector have expanded to 14 areas.
From the perspective of the proportion of modified plastics for automobiles, modified PP is currently the most widely used subclass of modified plastics for automobiles, accounting for 46%; followed by modified PA, accounting for about 8%. The proportion of the remaining sub-products is relatively small.
Domestic automotive modified plastics accounted for (%: %)
According to the market demand scale of automotive modified plastics and automobile production data in recent years, it can be seen that the current consumption of bicycle modified plastics has reached 150 kg/car. According to statistics, the market demand for automotive modified plastics in China is between 3.5 million and 5 million tons.
At present, there are thousands of enterprises in China engaged in the production of modified plastics, but there are only more than 70 enterprises above designated size (capacity of more than 3,000 tons). From the perspective of production capacity, domestic enterprises account for about 73%, and foreign or joint ventures account for about 27%. %, but from the market share, domestic market share is only 30%, while foreign companies have a market share of 70%.
According to relevant data, in 2005-2016, China's automobile production increased from 5.78 million to 28.319 million, with a compound growth rate of 15.60%. It is estimated that by 2022, the output of China's automobiles will be around 40 million. In the future, with the continuous improvement of modification technology, its application ratio in the automotive industry will continue to increase. It is expected that the total growth rate of automotive modified plastics in 2017-2022 will be around 6%. By 2022, the automobile will be changed. The total demand for plastics will exceed 6.4 million tons.
2017-2022 China's total demand for automotive modified plastics (unit: 10,000 tons,%)
China is the world's largest new energy vehicle market. In 2016, new energy passenger vehicle sales accounted for 43.7% of the world's total. In the next few years, it will grow at a rate of about 40% per year. By 2020, the output will reach 2 million units. Automobiles rely more on lightweight technology, so the amount of domestic bicycle modified plastics will increase significantly.
There are many kinds of Glass Door Locks, but mainly two
types which for glass cutting and no need glass cutting. The
advantage of the glass lock is that the glass doesn't need to cut-out and also
can keep safe better. So glass lock is more and more popular. And we JIANGYI
company is specialized in manufacturing all kinds of glass hardware for more
than 20 years. We persist to develop new models and use good materials to cope
with the increasing variety need of domestic and foreign markets.
