Promote lightweight vehicles: weight loss is an eternal issue


According to the report of the World Automobile Association, fuel consumption can be reduced by 6%-8% for every 10% reduction in vehicle weight. Lighter vehicles will help improve vehicle fuel economy and vehicle control stability. Energy resources can reduce emissions and meet environmental requirements. Automotive lightweighting has become an important label for automotive products and an important direction for the development of the automotive industry. The Ministry of Industry and Information Technology of China has also issued a document clearly stating that it is necessary to promote the development of lightweight vehicles.


Therefore, under the guidance of the policy and the market, the lightweight of automobiles has ushered in the spring of innovation and development. Faced with the broad market space of new energy vehicles, traditional car companies have laid out new energy strategies, and competition is becoming increasingly fierce. Lightweight technology will be the "nuclear weapon" in the new energy vehicle market. Aluminum alloy bodies, high-strength steel chassis, power systems, plastic covers, and material joining processes will all become new demands in the new energy vehicle market.


The trend of automotive plasticization is difficult to stop


Automotive plasticization is also a major trend in the international automotive industry today. According to a report released by Global Market Insight (GMI) Consulting, sales of the global automotive plastics market are expected to exceed US$50 billion by 2024. Parts made of plastic products will occupy an increasing proportion.


Statistics show that in 2016, the average global polymer composite material for each light-duty vehicle was about 150 kg. GMI predicts that by 2024, only in automotive power systems, the proportion of plastic products will be close to 10%, including core components such as engines, drive shafts, gears, transmissions and bearings. The proportion of plastic products in the chassis of the car will also exceed 9%. Polymethyl methacrylate (PMMA) in plastic materials benefits from its impact resistance, UV filtering, chemical resistance, high color accuracy, weather resistance, etc. GMI predicts that by 2024, PMMA-based automotive plastics market The scale will exceed $1.3 billion.
