1. PFA hose insulation
The PFA hose is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melt cohesiveness is enhanced, the solution viscosity is reduced, and the performance is unchanged compared with PTFE. This kind of resin can be directly processed into products by ordinary thermoplastic molding methods. Suitable for the production of corrosion-resistant parts, anti-wear parts, seals, insulation 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?
PFA hose in addition to excellent insulation, but also has a high degree of chemical stability: PFA hose can withstand all strong acids, including hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, strong alkali, strong oxidants, reducing agents and various organic solvents. Ideal for high purity chemical feeding use.
PFA hose very low coefficient of friction.
The PFA hose has excellent anti-stickiness, 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 hoses: PFA hoses have good dielectric properties, great resistance, and are small in all electrical insulation materials.

2. Teflon water pipe
Teflon high temperature water pipe is made of polytetrafluoroethylene (PTFE commonly known as Teflon, plastic king) material after extrusion sintering, drying, high temperature sintering, shaping and other processes made of special pipe.
Teflon is also called Teflon, Teflon, Teflon, Teflon, Teflon, Teflon, PTFE, Plastic King, English is Teflon, which is widely used in machinery, electronic appliances, automobiles, aerospace, chemicals, computers, Electric heating, military, communications and other important scientific and technological industries, such as micro transformers.
The mechanical properties of Teflon water pipes are relatively soft. It 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: able to aqua regia and all organic solvents;
Weather resistance: the best aging life in plastics;
High lubrication: with the smallest coefficient of friction in plastics (0.04);
Non-stickiness: has the smallest surface tension in solid materials without adhering to any substance;
Non-toxic: physiologically inert; excellent electrical performance, is the ideal C- class insulation material.

PTFE pipe is made of suspension polymerization PTFE resin by plunger extrusion processing. Among the known plastics, polytetrafluoroethylene has the best chemical resistance and dielectric properties. PTFE braided packing is a kind of good dynamic sealing material, which is made of expanded polytetrachloroethylene tape. It has low friction coefficient, wear resistance, chemical corrosion resistance, good sealing performance, no hydrolysis, no hard and other excellent properties. Gasket seals and lubricating materials used in various media, as well as electrical insulation, capacitor media, wire insulation, electrical instrument insulation, etc. used at various frequencies.
3. Teflon Board
PTFE plate (also called PTFE plate, Teflon plate, Teflon plate) is divided into two kinds of molding and turning. The molded plate is made of PTFE resin at room temperature by molding, and then sintered and cooled. The PTFE turning plate is made of PTFE resin by pressing, sintering and rotary cutting. Its products are widely used and have excellent comprehensive properties: high and low temperature resistance (-192 ℃-260 ℃), corrosion resistance (strong acid, strong alkali, aqua regia, etc.), weather resistance, high insulation, high lubrication, non adhesion, non toxic and other excellent characteristics. Polytetrafluoroethylene (English abbreviation Teflon or [PTFE,F4]), is known as/commonly known as "plastic king", Chinese trade name "Teflon", "Teflon" (Teflon), "Teflon", "Teflon", "Teflon", "Teflon" and so on.
It is a polymer compound formed by the polymerization of tetrafluoroethylene. Its structure is-[-CF2-CF2-]n-, which has excellent chemical stability and corrosion resistance (PTFE or F4 for short, is one of the most corrosion-resistant materials in the world today. "Plastic King" is commonly known as PTFE. It is a plastic with the best corrosion resistance. It is not known acid, alkali, salt, oxidant corrosion, is the aqua regia also helpless to it, so named plastic king, in addition to molten metal sodium and liquid fluorine, can withstand all other chemicals, widely used in all kinds of need to resist acid and alkali and organic solvents, sealing, high lubrication non-stick, electrical insulation and good anti-aging endurance, excellent temperature resistance (can work at 250 ℃ to -180 ℃ temperature for a long time).

Temperature -20~250 ℃(-4~482 °F), allowing quenching and quenching, or alternating hot and cold operation.
Pressure -0.1~6.4Mpa (full vacuum to 64kgf/cm2)
It has solved many problems in China's chemical, petroleum, pharmaceutical and other fields. PTFE seals, gaskets, gaskets. 3. PTFE seals and sealing gaskets are made of suspension polymerization PTFE resin molding. Compared with other plastics, PTFE has the characteristics of chemical resistance, it has been widely used as a sealing material and filling material.
