  1. FEP liquid delivery pipe

  FEP liquid delivery pipe is suitable for fluids, corrosive liquids and gases.

  The full name of FEP is Fluorinated ethylene propylene, which translates to fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer). The 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 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.

  The material 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. Semi-finished products include films and plates. Rod and single fiber. FEPs distributed in the US market include the Teflon brand of DUIPont, the Neoflo brand of Daikin, and the IHoustaflow brand of Hoechst Celanese. Its main purpose is to make linings for pipes and chemical equipment, surface layers of drums, and various wires and cables, such as aircraft hook wires, booster cables, alarm cables, flat cables and oil well logging cables. FEP film has been used as a thin coating for solar collectors.

  Polyperfluoroethylene propylene FEP or F46 is a copolymer of tetrafluoroethylene and hexafluoropropylene. The content of hexafluoropropylene is about 15%. It is a modified material of polytetrafluoroethylene.

  F-46 resin not only has similar characteristics to PTFE, but also has good processing properties of thermoplastics. Therefore, it makes up for the deficiencies of the difficult processing of PTFE, making it a material to replace PTFE, and is widely used in the production of wires and cables for electronic equipment transmission wires used under high temperature and high frequency, connecting wires inside electronic computers, Insulation layer of aerospace wires and special purpose installation wires, oil pump cables and winding wires of submersible motors.

  According to processing needs, F-46 can be divided into three types: pellets, dispersions and paints. Among them, the pellets can be used for molding, extrusion and injection molding according to their melt index; the dispersion is used for dipping and sintering; the paint is used for spraying.

  Second, the use of Fep heat shrinkable tube

  The full name of FEP is Fluorinated ethylene propylene, which translates to fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer). The 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 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 heat shrinkable tube volume resistance>1018ΩM, surface resistance>1013Ω, arc resistance>165 seconds, no leakage, low friction coefficient of kinetic friction 0.2-0.3 non-sticky, water, oil and water contact angle θ=114о, non-flammable air Combustion (oxygen index>95VOL%), the shrinkage ratio is 1.7:1, 4:1.

  Features: temperature-resistant polyfluoroethylene propylene (F46, FEP) heat shrinkable tube -200--200℃, fusible polytetrafluoroethylene (PFA) heat shrinkable tube -200--250℃, corrosion resistance is only elemental fluorine at high temperature, Alkali metals work with it, but have no effect on all other concentrated and dilute inorganic organic acids, alkalis, and esters.

  Fep heat shrinkable tube use:

  Teflon FEP heat-shrinkable tube has outstanding wear resistance, chemical corrosion resistance and high temperature performance, especially suitable for high temperature performance occasions, used for insulation protection and pressure relief at connection welds and identification of coated components.

  Shenzhen DanKai Technology Co., Ltd. (ShenZhen DanKai Technology Co.,ltd.), whose predecessor is Dongguan Dandi Insulation Material Co., Ltd.
