  1. The difference between F4 and F46

  Speaking of the difference between F4 and F46, I have to introduce to you what F4 and F46 are. Then I will teach you the distinction from the product itself, its functions and application areas.

  First introduce F4 to everyone

  English abbreviation: PTFE

  Chinese name: polytetrafluoroethylene

  Chinese alias: PTFE/Teflon/Teflon/teflon/Teflon/4F/King of Plastics

  English name: Polytetrafluoroethylene (English abbreviation is Teflon or [PTFE, F4])

  There is a material in chemistry called polytetrafluoroethylene, whose molecular formula is (C2F4)n. F is the abbreviation of fluorine in the periodic table of the chemical elements. From this, it can be easily inferred that F4 is the abbreviation of polytetrafluoroethylene. This F4 is confused with the other "F4".

  F4 is a kind of material that is resistant to acids, alkalis, and various organic solvents. It is almost insoluble in all solvents. Therefore, F4 is insoluble, insoluble, non-sealing, and non-welding.

  PTFE has the characteristics of high temperature resistance, high temperature resistance can reach 260 ℃, PTFE has a very low coefficient of friction, so it is not only used for lubrication, but also becomes an ideal coating for easy cleaning of the inner layer of water pipes.

  F46

  F-46 Polyperfluoroethylene Propylene is a fluoroplastic developed to overcome the disadvantages of poor processing and molding properties of PTFE.

  It is a copolymer of polytetrafluoroethylene (F4) and polyhexafluoropropylene (F-6). Polytetrafluoroethylene propylene (F4) is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. The famous application of polytetrafluoroethylene (F4) is the outer wall material of the Water Cube, which is the largest intensive use in the world.

  The high temperature resistance of F-46 is 200 ℃, except that the use temperature is slightly lower than that of polytetrafluoroethylene (F4), it almost maintains all its excellent properties. Polyperfluoroethylene propylene (F-46) F-46 is soluble, sealable, weldable, and has high thermal fluidity. It can be processed and molded by general thermoplastics, such as molding, extrusion, injection molding, etc., or Made into anti-corrosion coating.

  Therefore, F-46 is widely used in petrochemical anticorrosion projects.

  In summary, there are two differences between F4 and F46

  1. High temperature resistance

  F4 high temperature resistance 260℃

  F46 high temperature resistance 200℃

  2. Different solubility

  F4 is insoluble, non-sealing, non-welding

  F46 is soluble, sealable, and weldable

  Fep tube manufacturer

  colour:

  Common colors: transparent, black;

  Unusual colors: yellow, brown, green, blue

  characteristic

  Common features:

  Operating temperature: -200 degrees to 200 degrees

  Ease of processing: can be flanged, welded

  Common specifications: inner diameter * outer diameter (unit: mm)

  Metric system: 2*4 3*5 4*6 5*7 6*8 8*10 8*12 9*12 10*12

  12*14 14*16 16*18 18*20 20*22

  British system: 1/8 inch (1.6*3.2) 1/4 inch (3.96*6.35) 3/8 inch (6.35*9.525)

  1/2 inch (9.5*12.7) 3/4 inch (15.88*19.05) 1 inch (22.2*25.4)

  Other specifications can be produced, the inner diameter is 0.5mm to 200mm, and the wall thickness is 0.12mm to 3mm.

  3. What material is FEP?

  Many traders only know that FEP pipe is a straight pipe when customers ask about it. What is FEP used for? Where is it used? What material is FEP made of? Now Shenzhen Dankai gives you these common sense in popular science.

  The full name of FEP is Fluorinated ethylene propylene, translated as fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer) English trade name: Teflon. FEP is a class of chemical substances. FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene. The melting point of FEP crystal is 304°C and the density is 2.15g/CC (grams/cubic centimeter).

  FEP does not ignite and can prevent the spread of flames. It has excellent wear resistance, low friction coefficient, and can be used from low temperature to 392F. The material can be made into granular products for extrusion and molding, used as powder for fluidized bed and electrostatic coating, and can also be made into water dispersion.

  FEP can be applied to soft plastics, and its tensile strength, wear resistance, and creep resistance are lower than many engineering plastics. It is chemically inert and has a low dielectric constant over a wide range of temperature and frequency.

  FEP has excellent wear resistance, low friction coefficient, and can be used from low temperature to 392F. The material can be made into granular products for extrusion and molding, used as powder for fluidized bed and electrostatic coating, and can also be made into water dispersion. Semi-finished products include films and plates. Rod and single fiber. FEP film has been used as a thin coating for solar collectors.

  Polyperfluoroethylene propylene resin (FEP) has similar characteristics to polytetrafluoroethylene (PTFE), and has a good processing technology for thermoplastics, making it an important material to replace PTFE. F-46 (polyfluoroethylene propylene) is widely used in the production of wires and cables for electronic equipment transmission lines used under high temperature and high frequency, connecting lines inside electronic computers, aerospace wires, and other special purpose installation lines, oil mine logging Cables, winding wires of submersible motors, lead wires of micro motors, etc.

  Shenzhen DanKai Technology Co., Ltd. (ShenZhen DanKai Technology Co.,ltd.), whose predecessor is Dongguan Dandi Insulation Material Co., Ltd. Fluoroplastic Material Factory, established in 1998, specializes in FEP, PFA, PTFE and other fluoroplastic pipes R&D, production and sales of rod, sheet and film products and other insulating materials.
