Brief analysis of special rubber engineering plastics: lack of industrialization in new materials, rubber and plastics can be regarded as the senior 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 where rubber and plastics are mainly exported to developed countries in the middle and low end, many new material products have also been improved or functionalized, which is an upgrade of traditional products

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

special rubber refers to the 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 for industrial products. In special rubber, silicone rubber is widely used in daily life because of its soft texture, heat resistance and cold resistance. However, 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 in 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 hot spots worth following 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 automobile 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 and environmental protection. 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 overall development level, 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 of fluorosilicone rubber developed by Dow Corning STI of the United States is silastic, high temperature resistant, fuel resistant and solvent resistant, and the oil resistant low compression permanent deformation rubber ethylene/acrylate copolymer AEM developed by DuPont of the United States

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

the value of special engineering plastics lies in the substitution of imported raw materials. Plastics are a highly plastic material, 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 synthetic materials that have a sharp touch and can heal rapidly and repeatedly at room temperature. The researchers mixed the plastic with the metal, and the new synthetic material has both the self-healing ability of the plastic polymer and the conductivity of the metal

the researchers said that the material is very sensitive to compression and flexion, so the prosthesis made of this material will have better bending at the joint; 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 evolving and market value is 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, China's plastic products listed in the name of Suning bank were found to have registered 759000 tons at the Administration for Industry and commerce last year, a month on month increase of 6.98%. From January to June, China's cumulative output of plastic products was 29.298 million tons, with a cumulative year-on-year increase of 8.2%, up again from the year-on-year growth 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 are mainly ----- Professor Tong Lisheng/Director of New University of Wisconsin in the United States refers to special engineering plastics. Special engineering plastics are mainly used in national defense and military industry, automobile, 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 to 50 years. Professor Cao told that he also said: in the industrial chain, the technical research and development of domestic special engineering plastics are mainly concentrated in foreign countries, which are 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

weggs, the world's leading manufacturer of high-performance polyketone materials, recently announced that the company intends to launch new Paek (poly aryl ether ketone) high-performance engineering plastic products at the upcoming 2013k exhibition

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 saving and consumption reduction for demanding production fields such as aerospace and automobile manufacturing. Paek polymer has remarkable high temperature resistance effect, and is in urgent need of light R2 in aerospace and other fields - ring compression strength of inner paper (n/0.152m); Materials are widely used in many fields. In addition, high performance Paek engineering plastics also have the characteristics of moisture resistance, compression resistance and corrosion resistance. Therefore, the engineering plastics are often used to replace metal heavy materials and some traditional polymer materials that can not function in harsh environments. In view of the increasing market demand for Paek products, viggs increased the production investment of Paek

although the international market of special engineering plastics is promising, it can not 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
