Engineering plastics substitute import space is vast

Engineering plastics have been identified as a new type of new material in strategic emerging industries. For its future prospects, industry experts believe that the market demand for engineering plastics will continue to grow steadily, but many need to be imported from abroad. With the support of policies, Chinese companies are expected to Further substitute imports, increase self-sufficiency rate, and achieve greater development.
The growth of special engineering plastics is faster Engineering plastics are plastic materials that can withstand mechanical stress as structural materials and can be used in a wide temperature range and harsh chemical and physical environments. These materials have high mechanical strength, high rigidity, good dimensional stability, good heat resistance, and excellent electrical insulation. They are widely used in aerospace, electrical and electronics, automotive, petrochemical, defense, and military industries.
Specifically, engineering plastics are classified into general engineering plastics and special engineering plastics. The former include polyamide (PA), polycarbonate (PC), polyoxymethylene (POM), polyester (PBT), and polyphenylene ether (PPE). Etc. The latter includes polyphenylene sulfide (PPS), liquid crystal polymer (LCP), polysulfone (PSF), polyimide (PI), polyaryletherketone (PEEK), polyarylate (PAR), and the like. .
According to the data provided by the China Huaxin Industrial Planning Institute, the average annual growth rate of China's general engineering plastic consumption from 2004 to 2009 is 10%, and the demand in 2009 is 2.48 million tons, mainly for electronic appliances, construction and Automotive field. It is predicted that the demand for general engineering plastics will continue to grow rapidly during the 12th Five-Year Plan period, with a compound annual growth rate of 5.8% from 2009 to 2015. In terms of special engineering plastics, consumption in 2009 was about 22,500 tons, and the compound annual growth rate of demand from 2009 to 2015 is expected to be 17.3%, which is higher than that of general engineering plastics, and the demand is still in short supply.
Sustained self-sufficiency rate Compared with the growth in market demand, China's engineering plastics production capacity has grown faster, but it still cannot fully meet domestic demand and needs to be imported from abroad. Fang Hao, deputy general manager of the Consultation Division of China National Chemical Information Center, said that some types of domestic technology are not enough and cannot be produced and must be imported from abroad.
Data show that the average annual growth rate of the general engineering plastics production capacity from 2004 to 2009 was 39.8%, of which the composite annual growth rate of PC and PBT production capacity was 116.5% and 23.9% respectively. From 2004 to 2009, the general plastic self-sufficiency rate increased from 11% to 31%. From 2009 to 2015, the compound annual growth rate of the general engineering plastics production capacity was 7.6%, PC and PBT are still the main growth points, and the self-sufficiency rate in 2015 will increase to 41%.
The capacity and output of special engineering plastics are very small, and the market space is also very small. In the last century, it was listed as a strategic material and foreign countries banned shipments to China. Fang Hao believes that during the "12th Five-Year Plan" period, the country will continue to increase its policy and financial support, while considering the introduction of foreign technology at a suitable time, special engineering plastics will usher in relatively good opportunities for development.
For many sub-sectors in the engineering plastics industry, Fang Hao believes that the technological level of PA, PBT, POM, etc. is relatively high, and the industrialization is relatively mature. The relevant companies include Shenma, Lanxing New Materials, Yizheng Chemical Fiber, and Yuntianhua. .
It is also known that other companies related to engineering plastics in A shares include Shenzhen Huicheng and Pulit. Future prospects for the industrialization of these products are still uncertain, but related companies have been constantly hype by the market. For example, Shenzhen Huicheng’s closing price on December 14 reached 40.6 yuan, while the closing price on October 22 was only 20.1 yuan, an increase of more than 1 times.
