Polysilicon project approval reopens the gate
After encountering problems such as overcapacity and suspension of the launch, the polysilicon industry will usher in a new stage of development. Recently, the Ministry of Industry and Information Technology issued a notice on the issuance of the "Application Report for Polysilicon Industry Access (hereinafter referred to as "Notice")." The "Notice" requires all relevant departments to verify the materials of the applicants in accordance with relevant regulations, and submit the results and materials of the review to the Ministry of Industry and Information Technology before July 15. In this regard, a list of polysilicon enterprises meeting the entry conditions will be announced. "The above practices will accelerate the independent development of the entire industry and transition to the stage of authorizing production qualifications," said Li Shengmao, a senior researcher at China Investment Consulting. Loose approval The Ministry of Industry and Information Technology pointed out in the "Notice" that the provinces, autonomous regions, municipalities directly under the Central Government and the cities with separate plans and the industrial and information administration departments of the Xinjiang Production and Construction Corps are responsible for accepting applications for the admission of polysilicon enterprises in the region, and will work with relevant departments at the same level in accordance with the "polysilicon industry." The working procedures and requirements of the Access Conditions (hereinafter referred to as the “Conditionsâ€) and the “Polysilicon Industry Access Application Report†shall verify the materials provided by the enterprise in the application report, and submit the verification opinions and the company's report materials to the Ministry of Industry and Information Technology. Electronic Information Division. The "Notice" disclosed that after the relevant materials were submitted, the Ministry of Industry and Information Technology will also organize experts and entrust relevant testing institutions to review and inspect the application materials, and will publish a list of polysilicon enterprises that meet the entry conditions in the form of announcements with the relevant ministries. Just two years ago, the polysilicon industry ushered in regulation due to overcapacity. In 2009, the State Council's No. 38 Document “Suggestions on Suppressing Overcapacity in Some Industries and Repetitive Construction to Guide the Healthy Development of Industries†ranked polysilicon as one of the top ten industries with overcapacity. The polysilicon industry was also labeled as “overcapacityâ€. , "high pollution" and other labels. In January 2011, the Ministry of Industry and Information Technology, the Ministry of Industry and Information Technology, the Ministry of Environmental Protection and other relevant departments have also formulated the "polysilicon industry access conditions", requiring solar-grade polysilicon reduction power consumption before the end of 2011 must be less than 60 kWh / kg, reducing tetrachloroethylene in the exhaust gas The recycling rate of silicon, hydrogen chloride and hydrogen is not less than 98.5%, 99% and 99%. Before the end of 2011, the solar-grade polysilicon production line with integrated power consumption greater than 200 kWh/kg will be phased out. At the same time, in principle, the new construction of polysilicon projects will no longer be approved. After the issuance of the Notice, relevant departments of various places will reopen the channel for approval of polysilicon projects. As one of the domestic polysilicon production giants, Jiangxi Saiwei spokesman Yao Feng said, “Polysilicon is a capital- and technology-intensive industry, and at the same time, it has high requirements for environmental protection. This requires a threshold for entry. At the same time, it competes in the market. In the development of the regulated industry, it is also necessary to enter the threshold." "The stronger the stronger" In January of this year, after the introduction of the "Conditions", the filing materials for new polysilicon enterprises were pressed on the desks of governments at all levels. During the past six months, many companies have rectified the company in response to the relevant provisions of the "Conditions", hoping to finally pass the review. In the view of some market participants, the requirements for the "Plastic Industry Access Conditions" are still relatively high, and many domestic enterprises cannot reach them, and they face many difficulties. Among them, especially the foreign companies implement technical blockade, China's polysilicon purification technology can only be obtained through various indirect ways, but after all, it is not the most advanced, many companies can not achieve closed loop. For the practice of the relevant state departments, Li Shengmao pointed out that after the final list is released, the production order of the polysilicon industry may also undergo some changes. The business of most middle and lower-end companies "may be concentrated in the hands of these polysilicon companies on the list." He believes that in this wave of polysilicon industry regulation, polysilicon leading enterprises are not expected to be greatly affected, in contrast, the survival space of SMEs with no technology and capital will be further squeezed. The gap between these companies and large companies will grow larger. Jiang Qian, chief energy analyst of China Investment Consulting, pointed out that 80% of the domestic polysilicon manufacturers are small enterprises, and the production capacity is generally on the scale of several hundred tons. These enterprises are not as large as the scale and energy consumption. It will be the “big limit†for the elimination of these SMEs.

Fluorine rubber 26 is commonly called No. 2 rubber in China, DuPont brand fluorine rubber a, which is a copolymer of vinylidene fluoride and hexafluoropropylene, and its comprehensive performance is better than No. 1 rubber.
Fluoroelastomer 246, commonly known as the third largest rubber in China, DuPont Brand Fluoroelastomer B, is a terpolymer of vinylidene fluoride, tetrafluoroethylene and hexafluoropropylene, with fluorine content higher than 26 and good solvent resistance.
Fluoroelastomer TP, commonly known as tetrapropylene rubber, Asahi brand aflas, is a copolymer of tetrafluoroethylene and propylene hydrocarbons, which has excellent resistance to water vapor and alkali.
Vinylidene fluoride rubber, DuPont brand fluororubber, is a quaternary copolymer of vinylidene fluoride, tetrafluoroethylene, perfluoromethyl vinyl ether and vulcanization point monomer, with excellent low-temperature performance.
Perfluoroether rubber, DuPont Karez, has excellent high temperature resistance, high fluorine content, and excellent solvent resistance.
Fluorosilicone rubber has excellent low temperature performance and certain solvent resistance.
Fluoroelastomer is mainly used in automobile and automobile industry. It is mainly used for oil seal and O-ring due to its excellent high temperature resistance, oil resistance and medium resistance.
