With the economic development, the demand for engineering plastics in China has soared, but the requirements for plastics in various industries have become higher and higher. High-end raw materials are urgently imported from abroad. However, with the support of policies, Chinese enterprises are not expected to further import and promote self-sufficiency. Rate, thus losing greater development.
Domestic engineering plastics replace imported modified plastics
The data shows that the compound annual growth rate of plastics in the Pu film project is 39.8%, and the compound annual growth rate of PC and PBT capacity is 116.5% and 23.9%, and the self-sufficiency rate of plastics is increased from 11% to 31. %.2009-Modified Plastics In 2015, the compound annual addition rate of plastic production capacity of the film project was 7.6%. PC and PBT were still the main increase points. In 2015, the self-sufficiency rate will be increased to 41%.
Specifically, engineering plastics are divided into general engineering plastics and special project plastics. The former includes polyamide (PA), polycarbonate (PC), polyoxymethylene (POM), polyester (PBT), and polyphenylene ether (PPE). The latter, such as liquid crystal polymer (LCP), polysulfone (PSF), polyimide (PI), polyaryletherketone (PEEK), polyarylate (PAR), and the like.
The special project plastics production capacity and production volume are very small, and the market space is also very small. In the last century, it was listed as a strategic material for modified plastics, and the foreign countries imposed embargo on China. Fang Hao believes that during the "Twelfth Five-Year Plan" period, the country will continue to increase policy and financial support, while thinking about introducing domestic martial arts in appropriate opportunities, special project plastics will usher in better development opportunities.
Project plastics are plastic materials that are mechanically stressed as tissue data and can be used in a wide range of temperatures and in relatively harsh chemical and physical conditions. This kind of data has high mechanical strength, high rigidity, good dimensionality, good heat resistance and high electrical insulation. It is widely used in aerospace, electrical and electronic, automotive, petrochemical, defense and military industries.
