What is 1. FEP tube
The full name of FEP is Fluorinated ethylene propylene, which translates as fluorinated ethylene propylene copolymer (perfluoroethylene propylene copolymer). FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene. The FEP crystals had a melting point of 304 ° C. and a density of 2.15g/cc. FEP can be applied to soft plastics, its tensile strength, wear resistance, creep resistance is lower than many engineering plastics
2. FEP tube characteristics:
1. Can withstand extreme cold and extreme heat: It remains stable in a wide temperature range, from very low to very high (specific temperature not given).
2. No water or oil: the surface is smooth, and it is difficult for water and oil to adhere.
3. Stable electrical performance: At different temperatures (from 60Hz to 60 MHz), the insulation performance is good to ensure safe electricity use.
4. Even if it is wet, it is not conductive: even if the surface is damaged and comes into contact with water, it will not form a conductive path, which is very safe.
5. Very high insulation: internal and surface are very difficult to conduct electricity, can resist long time arc without leakage.
6. Strong corrosion resistance: In addition to fluorine and some alkali metals at extremely high temperatures, it is hardly attacked by any strong and weak acids, alkalis or chemicals.
Very little water absorption: almost no water absorption, water absorption rate is less than 0.01%.
Harmless to the human body: the material is safe and has no adverse effects on the organism.
9. flame retardant: in the air will not burn, excellent fire performance (oxygen environment ignition point super high).
High transparency: excellent light transmission, is the highest light transmittance in plastic.
11. Anti-ultraviolet weather: prolonged exposure to the sun or ozone is not easy to damage.
12. Easy processing: can be easily self-enclosed, welding, flanging or made into different shapes of pipes and plates.
3. FEP tube use:
1. LCD screen production equipment
2. Single-end light-emitting fiber protection tube
3. Heat exchanger and steam piping
4. High purity chemical liquid transfer pipe
5. Corrosion resistant material conveying pipeline, used for strong acid and alkali, etc.
6. Wire and cable sheath, suitable for a variety of signal frequencies
7. Submersible motor insulation pipe
8. Air conditioning line collection pipe
9. Perfluorinated plastic O-ring matching pipe
4. FEP Tube Applications
1. Wire protection: FEP tube because of good insulation performance, can be used to wrap the wire, to prevent leakage.
Chemical liquid transportation: This kind of pipe can resist most chemical substances and is suitable for transporting chemicals.
3. Water sample: When detecting groundwater, FEP pipe can keep the water quality pure, does not interfere with the test results, and is convenient to pump the water to the ground for inspection.
4. Heat shrinkable sleeve application: FEP can also be made into heat shrinkable tube, used in the printing machine to help transport ink, its surface is smooth, do not let the ink adhesion or discoloration.
5. Medical use: In medical treatment, FEP tube is used as a catheter, such as in endoscopy, to ensure that the liquid injected into the patient's body is clean and pollution-free, and easy to disinfect.
6. Radiator: FEP tube heat exchanger durable and easy to weld, improve equipment life.
7. water treatment: FEP tube can resist ultraviolet light, water through it, with ultraviolet light can effectively kill bacteria, while the tube is not damaged. This not only cleans the water, but also does not reduce the water flow, especially suitable for purifying sewage and groundwater, combined with filtration technology, can make dirty water into safe water for drinking.
