1. PFA hose insulation
PFA hose is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melt adhesion is enhanced, the melt viscosity is reduced, and the performance is unchanged compared with polytetrafluoroethylene. This kind of resin can be directly processed into products by ordinary thermoplastic molding methods. Suitable for making corrosion-resistant parts, wear-reducing and wear-resistant parts, seals, insulating parts and medical equipment parts, high-temperature wires, cable insulation, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers.
PFA hose has very good physical properties. How much do you know about its advantages?
In addition to excellent insulation, PFA hoses also have a high degree of chemical stability: PFA hoses can withstand all strong acids, including hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, etc., strong alkalis, strong oxidants , Reducing agent and various organic solvents. It is very suitable for feeding high-purity chemicals.
PFA hose has a very low coefficient of friction.
The PFA hose has excellent adhesion resistance, and the inner wall of the PFA hose tube is not easy to adhere to colloids and chemicals.
PFA hose has excellent aging resistance and can be used outdoors for a long time.
Electrical insulation properties of PFA hose: PFA hose has good dielectric properties, extremely high resistance, which is small among all electrical insulation materials.

2. Teflon water pipe
Teflon high temperature water pipe is a special pipe made of polytetrafluoroethylene (PTFE commonly known as Teflon, plastic king) material after extrusion and sintering, drying, high temperature sintering, and shaping.
Teflon is also called Teflon, Teflon, Teflon, Teflon, Teflon, Teflon, Plastic King, and Teflon in English. It is widely used in machinery, electronic appliances, automobiles, aerospace, and chemicals. , Computers, electric heating, military, communications and other important technology industries, such as miniature transformers.
The mechanical properties of Teflon pipes are relatively soft. Has a very low surface energy.
Teflon water pipe has a series of excellent performance:
High temperature resistance: long-term use temperature 200~260 degrees;
Low temperature resistance: still soft at -100 degrees;
Corrosion resistance: resistant to aqua regia and all organic solvents;
Weather resistance: the best aging life among plastics;
High lubrication: has the smallest coefficient of friction in plastics (0.04);
Non-sticky: It has the smallest surface tension among solid materials and does not adhere to any substances;
Non-toxic: with physiological inertness; excellent electrical properties, is an ideal C-level insulating material.

The polytetrafluoroethylene pipe is made of suspension polymerized polytetrafluoroethylene resin through plunger extrusion processing. Among the known plastics, PTFE has the best chemical resistance and dielectric properties. Polytetrafluoroethylene braided packing is a good dynamic sealing material. It is woven from expanded polytetrachloroethylene tape. It has low friction coefficient, wear resistance, chemical corrosion resistance, good sealing, no hydrolysis, no Excellent performance such as hardening. Used for gasket seals and lubricating materials working in various media, as well as electrical insulation, capacitor media, wire insulation, electrical instrument insulation, etc. used under various frequencies.
Three, PTFE board
Polytetrafluoroethylene board (also called tetrafluoroethylene board, Teflon board, Teflon board) is divided into two types: molding and turning. Made by cooling. The PTFE turning board is made of PTFE resin by pressing, sintering and peeling. Its products are widely used and have extremely superior comprehensive performance: high and low temperature resistance (-192℃-260℃), corrosion resistance (strong acid, strong alkali, aqua regia, etc.), weather resistance, high insulation, high lubrication, non-sticking, Non-toxic and other excellent characteristics. Polytetrafluoroethylene (English abbreviation Teflon or [PTFE,F4]), known as "Plastic King", Chinese trade names "Teflon", "Teflon" (teflon), "Teflon" , "Teflon", "Teflon" and so on.
It is a polymer compound formed by polymerization of tetrafluoroethylene. Its structure is simplified as -[-CF2-CF2-]n-, which has excellent chemical stability and corrosion resistance (polytetrafluoroethylene referred to as PTFE or F4 It is one of the most corrosion-resistant materials in the world today. "Plastic King" is the common name of polytetrafluoroethylene. It is a kind of plastic with the best corrosion resistance. It is not affected by known acids, alkalis, salts, and oxidants. Corrosion, even aqua regia, is helpless, so it is named Plastic King. In addition to molten sodium and liquid fluorine, it is resistant to all other chemicals. It is widely used in all kinds of acids and alkalis and organic solvents that require resistance to acids, alkalis and organic solvents, airtightness, and high lubrication. Non-stick, electrical insulation, good aging resistance, excellent temperature resistance (can work for a long time at a temperature of +250°C to -180°C).

The temperature is -20～250℃ (-4～+482°F), allowing rapid cooling and heating, or alternate operation of cooling and heating.
Pressure -0.1～6.4Mpa (Full vacuum to 64kgf/cm2) (Full vacuum to 64kgf/cm2)
Its emergence has solved many problems in my country's chemical, petroleum, pharmaceutical and other fields. Polytetrafluoroethylene seals, gaskets, gaskets. Polytetrafluoroethylene seals and gaskets are made of suspension polymerized polytetrafluoroethylene resin molding. Compared with other plastics, PTFE has the characteristics of chemical resistance, and it has been widely used as a sealing material and filling material.
