The National Development and Reform Commission stated on November 23, 2009 that the special security case had a negative impact on the tire industry in China. It involved not only 12% of production capacity, but also affected the supply of raw materials such as synthetic rubber and carbon black in the upper reaches of the industry. Problems such as laid-off unemployment, in addition, there will be a collateral effect, potentially harmful. The National Development and Reform Commission stated that it is necessary to take effective measures in five areas and strive to maintain the healthy development of the tire industry. First of all, in the absence of a proposal from the United States's inner tire manufacturer, the United States imposed special protection on imported tires in China, which not only violated the WTO rules, but also violated the commitments made at the G20 financial summit and was an abuse of the safeguard clause. Therefore, it should be actively appealed to minimize losses; Secondly, encourage and support the reorganization and acquisition of domestic backbone enterprises, establish large-scale tire enterprise groups, form large-scale tire enterprise groups with scale advantages, strive to build strong brands, break brand bottlenecks, and increase market share. Third, assisting and supporting the strong, supporting key tire companies to carry out structural adjustment and technological transformation, the development of high-performance radial tires, promote product upgrading, and enhance competitiveness. Properly control the growth of tire production capacity and ease the contradiction of oversupply. Fourth, strengthen enterprise technology research and development and innovation capacity building, set up a tire R & D center and tire testing ground, build a technical R & D public platform, and gradually improve the technological innovation system. Finally, formulate mandatory technical specifications such as tire quality, safety, environmental protection, energy conservation and raw material consumption, establish technical standards and certification systems for tire export enterprises, strengthen market supervision, rectify market order, and prevent vicious competition.

Polyoxymethylene (POM), also known as acetal , polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts that require high stiffness, low friction and excellent dimensional stability.
2 Properties
♣POM is characterized by its high strength, hardness and rigidity to -40 °C. POM is intrinsically opaque white, due to its high crystalline composition, but it is available in all colors.
♣POM homopolymer is a semi-crystalline polymer (75-85% crystalline) with a melting point of 175° Celsius
♣POM copolymer has a slightly lower melting point of 162 – 173° Celsius.
3 POM advantages
♥High abrasion resistance
♥Low coefficient of friction
♥High heat resistance
♥Good electrical and dielectric properties
♥Low water absorption
