With the continuous development of the automotive industry, the consumption of automobiles has expanded rapidly, and the demand for automotive plastics has also increased. The market for automotive plastics such as polyurethane and nylon materials has further expanded.
According to reports, the market value of plastics in the BRIC countries (Russia, China, Brazil and India) reached US$1,1244.4 million in 2014, and the expected compound annual growth rate between 2015 and 2020 is expected to reach 15.4%. By 2020, the global automotive plastics market will be compounded. The annual growth rate is expected to reach 13%. As the demand for lightweight vehicles expands, automotive plastics are entering a period of vigorous development.
It is reported that a large number of plastic parts have been used in auto parts, including bumpers, wheel covers, license plates, instrument panels, door panels, knobs, and even engine covers and air intake systems. Experts pointed out that polyamide (PA, nylon) materials are mainly used in power, chassis parts and structural parts, accounting for about 20% of the plastics of the whole vehicle; polycarbonate, polyoxymethylene, modified polyphenylene ether and thermoplastic polyester, etc. The materials are mainly used in electronic and electrical parts and structural parts, accounting for about 15% of the plastics of the whole vehicle. Modified polyphenylene ether (PP) and abs engineering plastics and their alloy materials are mainly used in interior and exterior parts. As the grades of vehicles increase, the application of engineering plastics increases, and the proportion of abs and its alloys increases.
Modified polypropylene material
The modified polypropylene plastic has strong competitiveness in the automotive industry. The modified PP products are used in the car. The heat resistance can be increased from 80 °C to 145 °C - 150 °C, and can withstand high temperature 750 - After 1000h, it will not age and will not crack. According to the global plastics report, the upgrade of automotive lightweight demand will drive the rapid development of the polypropylene market. In 2014, the global polypropylene market demand reached a record high of 95.9 billion US dollars. With the development of the industry, the global polypropylene market is expected to be scaled by 2020. It will grow at a rate of 6.3%, the market size will reach 138.36 billion US dollars, and the global polypropylene production will reach 70.81 million tons.
Polyurethane vehicle materials
With the development of the automobile industry, the consumption of automobiles has expanded rapidly, and the demand for plastic polyurethane for vehicles has been increasing. In the plastics used in modern automotive materials, the amount of polyurethane is not only the largest, but also covers a wide range of applications, from the car to the car. External components, from soft to hard, from lightweight to compact, and high-strength glass-reinforced products.
Reinforced nylon material
As an important part of automobile parts, the oil pan is gradually developed from cast aluminum parts to injection molded parts made of reinforced nylon materials, such as PA66GF35 and PA6GF35, which have become one of the new materials for lightweight automobile oil sump. Nylon material has outstanding advantages in weight reduction. The molding processability of nylon material is good, which not only improves production efficiency, but also reduces production cost, helps to improve product quality, reduce scrap rate, superior work reliability and durability. And work adaptability at low temperatures, so as the demand for lightweight vehicles is growing, the demand for reinforced nylon materials is strong.
