  1. Transparent FEP tube

  Uses of FEP transparent tube:

  1. Liquid crystal manufacturing device;

  2. The whole body single-end light-emitting single-core optical fiber tube;

  3. Heat exchanger and steam piping;

  4. High purity reagent delivery tube;

  5. Various corrosive media (harsh solvents) pipelines;

  6. Various frequency wire and cable sheath, slot insulation tube;

  7. Slot insulating pipe for submersible motor;

  8. Pipes for air-conditioning wiring harness components;

  9. All-inclusive fluorine plastic type 0 sealing ring tube.

  Transparent FEP tube utilization characteristics:

  1. High and low temperature resistance: -200--200℃;

  2. Non-sticky, fight water, fight oil;

  3. Electrical reliability, high insulation;

  4. The dielectric constant viscosity at 60HZ-60MHZ is 2.1 at both high and low temperature. Even if the surface is damaged by diving, there will be no conductive tracks;

  5. Volume resistance>1018ΩM, surface resistance>2*1013ΩM, arc resistance>165 seconds without leakage;

  6. Corrosion resistance, only elemental fluorine at high temperature, alkali metals play a role with it, and have no effect on all other concentrated and dilute inorganic organic acids, alkalis, and esters;

  7. Low water absorption: low absorption rate <0.01%;

  9. Non-combustibility: Will not burn in the air (oxygen index>95VOL.%);

  10. High transparency: the light refractive index is low among all plastics;

  11. Weather resistance: can be exposed to ozone and sunlight for a long time;

  12. Ease of secondary processing: self-sealing, self-welding, flanging, and coiled pipes can be made.

  2. PTFE Rotary Cutting Tube

  The PTFE tube is extruded with high-quality plunger. It adopts a special processing technology to make the steel pipe and the plastic tube tightly combined. It can withstand a positive pressure of 1.6Mpa, a negative pressure: 77Kpa; it can be at -60℃~+260 Normal use within ℃, with reliable and excellent corrosion resistance. Transporting highly corrosive gases and liquids at high temperatures cannot be replaced by other pipelines.

  The PTFE rotary cutting tube is cut into a rotary cutting tube with a machine after the production of the PTFE extruded tube is completed.

  PTFE rotary cutting tubes are widely used in important technology industries such as machinery, electronic appliances, automobiles, aerospace, chemical industry, computers, electric heating, military, communications, etc., such as miniature transformers.

  Characteristics of PTFE Rotary Tube:

  1. High chemical stability: can withstand all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, etc., strong alkalis, strong oxidants, reducing agents and various organic solvents . It is very suitable for feeding high-purity chemicals.

  2. Low coefficient of friction: The coefficient of friction is generally only 0.04, which is a very excellent self-lubricating material, and the coefficient of friction does not change with changes in temperature.

  3. Excellent anti-sticking property, and the inner wall of the tube is not easy to adhere to colloids and chemicals.

  4. Excellent aging resistance, can be used outdoors for a long time.

  5. Excellent electrical insulation performance: PTFE is a highly non-polar material with good dielectric properties, great resistance, and a dielectric constant of about 2.0, which is the smallest among all electrical insulation materials.

  Three, high pressure FEP 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 (2.1) in a wide temperature and frequency range.

  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.
