Polytetrafluoroethylene has a very high chemical resistance, such as in concentrated sulfuric acid, nitric acid, hydrochloric acid, even boiling in aqua regia, its weight and performance are unchanged, and almost insoluble in most solvents, only slightly soluble in paraffins (about 0.1g / 100g) above 300 ℃. Polytetrafluoroethylene is non hygroscopic, non combustible, extremely stable to oxygen and ultraviolet, so it has excellent weather resistance. It should be noted that polytetrafluoroethylene can not withstand strong reduction atmosphere melting of alkali metals, ammonia alkali solution (alkali metals dissolved in liquid ammonia), some fluorides (such as TFA), naphthalene sodium salt, etc. can rapidly corrode polytetrafluoroethylene products. The dielectric constant and loss of polytetrafluoroethylene are very low in a wide frequency range, and the breakdown voltage, volume resistivity and arc resistance are high. Polytetrafluoroethylene can be processed by compression or extrusion; it can also be made into water dispersion, used for coating, impregnation or fiber. Polytetrafluoroethylene is widely used in the industries of atomic energy, national defense, aerospace, electronics, electrical, chemical industry, machinery, instrument, instrument, architecture, textile, metal surface treatment, pharmacy, medical treatment, textile, food, metallurgy and smelting as high and low temperature resistant, corrosion-resistant materials, insulating materials, anti sticking coating, etc., making it an irreplaceable product.
Huzhou Ningxin new material science and Technology Co., Ltd. is located in Deqing County, Zhejiang Province. It is a member of the fluorine plastics processing professional committee of China Plastics Association. It has been engaged in the development, production and sales of fluorine plastics products for nearly 20 years. Its main products are: polytetrafluoroethylene plate, rod, tube, film, various sealing gasket, washer, plastic special-shaped parts, fluorine plastics special mechanical products, etc. The company has obtained ISO9001 quality management system certification, and is rated as a provincial high-tech enterprise in 2019. In recent years, our company has a high reputation in marine engineering, ship industry, chemical anti-corrosion industry and mechanical parts. The product has obtained SGS test certificate, UL94 flame retardant certificate and FDA food level test certificate.
Over the years, the company's products are not only used in domestic petroleum, chemical industry, medicine, electronics, machinery, automobile, smelting, shipbuilding, transportation and other fields, but also exported to many countries and regions, favored by the majority of users. Recently, the company has increased investment to develop new fluoroplastic materials and products, and launched more new products to meet the needs of more users at home and abroad.
