Brief analysis of special rubber engineering plastics: lack of industrialization

among new materials, rubber and plastics can be regarded as veteran materials. These two substances can be seen everywhere in our daily life, but if we enter the field of new materials, it is a new topic that needs to be explored for a long time

in fact, new materials are not opposed to traditional materials. Many of them are upgraded to new materials because they have some new functions after improvement or functionalization. Professor caoxianwu, School of mechanical and automotive engineering, South China University of technology, once told me

in the field of rubber and plastics, many new material products have also been improved or functionalized, which are the upgrading of traditional products

first, let's briefly understand special rubber and engineering plastics

Special Rubber refers to rubber with the characteristics of high temperature resistance, oil resistance, ozone resistance, aging resistance and high air tightness. Commonly used are silicone rubber, various fluororubber, polysulfide rubber, chlorohydrin rubber, nitrile rubber, polyacrylate rubber, polyurethane rubber and butyl rubber, which are mainly used in special occasions requiring certain characteristics. Special rubber is mainly used in industrial products. In special rubber, silicone rubber is widely used in daily life because of its soft texture, heat resistance and cold resistance, but fluororubber also has prospects. Professor Cao explained to the financial weekly

in the 12th Five Year Plan, engineering plastics specifically refers to special engineering plastics. Its main label is high performance, specifically refers to engineering plastics with a long-term use temperature of more than 150 ℃. It is mainly used in high-tech, military, aerospace, aviation and other industries

according to the data of the Materials Science Laboratory of the financial weekly report, among the 62 listed companies involved in rubber business, HTC new material (5.62,0.00,0.00%) () and Yanggu Huatai (9.610,0.00,0.00%) () deserve attention; Among the 156 listed companies involved in plastics, Jinfa Technology (5.09,0.03,0.59%) () this year's 800000 ton environmental friendly high-performance automotive plastic project has begun to be prepared. The company said that the expert team has closely carried out the project in Kunshan. The PVDF film project for crystalline silicon solar cells and the composite intelligent energy-saving film project recently developed by fosu Technology (3.86,0.02,0.52%) are also market hotspots worthy of follow-up

insufficient industrialization of domestic raw materials

although special rubber and engineering plastics are far from daily life, the market demand still exists

the special synthetic rubber industry will be the direct beneficiary of the sustainable development of the automotive industry. In addition to the automotive industry, the demand for special synthetic rubber products is also growing in many industries, such as building materials, medical treatment, coal, electric power, electronics, military industry, new energy, environmental protection and so on. In 2012, the market scale of synthetic rubber will exceed 850billion yuan, and the market scale of special rubber will also grow rapidly year-on-year, which is expected to exceed 300billion yuan

however, the domestic special rubber industry is still in the initial stage of development. At present, the main problems are the low level of overall development, the generally small production scale of enterprises in the industry and the low added value of products. Moreover, the domestic per capita rubber consumption still lags far behind that of developed countries in the world

in fact, according to the overall situation of the current domestic special rubber market, the competitiveness of domestic special rubber enterprises has obviously fallen behind. In fact, most of the special rubber market is occupied by foreign enterprises, while domestic special rubber enterprises occupy less than 1/3 of the market share

the main reason is that the industrialization of domestic raw materials is not enough, and most of the high-end technologies are concentrated abroad. Professor Cao thinks so

it is reported that in order to meet the special requirements of the automotive industry, new varieties and brands of special rubber have been continuously developed, such as the high-strength HNBR developed by Zeon company in Japan; Low temperature resistant fluoroether rubber developed by DuPont; G7000 series products with low compression set and good processability developed by Daikin company of Japan; The brand developed by Dow Corning STI is silastic, high temperature resistant, fuel resistant and solvent resistant fluorosilicone rubber, and the oil resistant low compression permanent deformation rubber ethylene/acrylate copolymer AEM developed by DuPont

however, this field is still in its infancy in China. Shanghai Institute of organic chemistry has developed high-performance perfluoroether rubber and conducted small-scale, pilot and application tests

the value of special engineering plastics is to replace imported raw materials. Plastic is a substance with strong plasticity, and its characteristics determine that it is unimaginable to expand its new fields

for example, recently, the scientific research team of Stanford University in the United States developed an artificial synthetic material that has a strong sense of touch and can heal rapidly and repeatedly at room temperature. Researchers mixed this plastic with metal, and the new synthetic material has both the self-healing ability of plastic polymers and the conductivity of metals

the researchers said that this material is very sensitive to compression and buckling. Because the male airport island sea crossing bridge and the Youth City project are of great significance to the economic and social development of Malaysia, the prosthesis made of this material will have better curvature at the joints; Electrical equipment and wires covered with this material can also be self-healing. The next goal of the research team is to make the material more transparent and elastic, so that it can be applied to the outer surface of electronic devices or display screens

innovation is constantly evolving, and the market value is also constantly expanding

according to the data, in June, the output of plastic products in China was 5.588 million tons, an increase of 9.23% month on month and 4.6% year on year. In June, the export of plastic products in China was 759000 tons, with a month on month increase of 6.98%. From January to June, the cumulative output of plastic products in China was 29.298 million tons, with a cumulative year-on-year increase of 8.2%, rising again from the year-on-year growth rate of 7.5% from January to may, the fourth consecutive month of growth

the engineering plastics supported by China in the 12th Five Year Plan mainly refer to special engineering plastics. Special engineering plastics are mainly used in national defense and military industry, automobiles, aircraft, electronic information products, etc. at present, most of the special engineering plastics in China have not been industrialized, while foreign countries such as Japan and the United States have been industrialized for 40 or 50 years. Professor Cao told that he also said: in the industrial chain, the technological research and development of domestic special engineering plastics is mainly concentrated abroad, which is mainly monopolized by multinational enterprises such as Bayer and DuPont. The molding and processing are in China, and the sales are also in China. Domestic raw material technology still needs support

viggs, the world's leading manufacturer of high-performance polyketone materials, has recently announced that the company intends to launch Paek at the upcoming 2013k exhibition to see whether it meets the provisions of national standards or industry standards (polyaryl ether ketone) high-performance engineering plastic products

weigs said that advanced engineering plastics (such as Paek) not only have light quality and low cost, but also can solve the problem of energy conservation and consumption reduction for demanding production fields such as aerospace and automobile manufacturing. Paek polymer has remarkable high temperature resistance and is widely used in aerospace and other fields in urgent need of lightweight materials. In addition, high-performance Paek engineering plastics also have the characteristics of moisture resistance, compression resistance, corrosion resistance and so on. Therefore, this engineering plastic is often used to replace metal heavy materials and some traditional polymer materials that cannot function in harsh environments. In view of the rising market demand for Paek products, viggs increased the production investment of Paek

although the international market of special engineering plastics is promising, it still cannot escape the technical barrier of doom like other new materials in China

in China, general plastics and special engineering plastics that have not been industrialized, as long as they can replace the import of raw materials, represent a great market potential. Special engineering plastics are expected to expand in the field of consumer electronics, as well as in transportation and energy-saving buildings. Professor Cao told me
