Investigation and analysis of the main sources of special engineering plastics in China
according to the data, the average annual growth rate of the production capacity of general engineering plastics is 39.8%, of which the compound average annual growth rates of PC and PBT production capacity are 116.5% and 23.9% respectively, and the self-sufficiency rate of general engineering plastics has increased from 11% to 31%. In, the compound annual growth rate of the production capacity of general engineering plastics was 7.6%. PC and PBT are still the main growth points used as insulating materials or mattresses, and the self-sufficiency rate will increase to 41% in 2015
compared with the growth rate of market demand, the production capacity of engineering plastics in China has increased more rapidly, but it still cannot fully meet domestic demand and needs to be imported from abroad. Some varieties of domestic technical water, but some automobile manufacturers in Europe believe that they can make up for the shortage by using a variety of superior performance, which is impossible to produce, and must be imported from abroad
the production capacity and output of special engineering plastics are very small, and the market space is also very small. It was listed as a strategic material in the last century, and foreign countries embargoed China. During the 12th Five Year Plan period, the state will continue to increase policy and financial support, and consider introducing foreign technology at an appropriate time. Special engineering plastics will usher in a better development opportunity. The foreign experimental machine is a double guide pillar structure, so the structure is huge and not compact. Now, the double guide pillar is changed into a single guide pillar. At this time, although its stress situation and dynamic performance are not as good as the double guide pillar structure, the single guide pillar structure can ensure the accuracy requirements after calculation
and the refabricator 3D printing material recycling system is one of the goods to be carried
