1. PTFE white curly staple fiber is generally manufactured using the membrane splitting method, fiber strength is greater than the brown fiber produced by the emulsion spouting method, fiber can also be used to add color technology as needed to make a variety of colored fibers. It is suitable for high temperature environment, excellent chemical stability, low shrinkage rate, anti-aging and other characteristics. 2.

2. PTFE long fiber is a monofilament fiber manufactured by traction method, mainly used in the manufacture of PTFE sewing thread or for the weaving of base fabrics.

Advantages of FEP features

1. FEP can also be made into heat shrinkable tubes, which can be used for coating transfer rollers in printing presses. 2.High surface quality can prevent print adhesion, contamination and discoloration. 3. In the medical industry, FEP tubes are mainly used as catheters or in the field of endoscopy. 4. It also prevents contamination of the delivered liquid during the injection process. 5. Therefore, the biocompatibility of FEP for medical use is also excellent. 6. FEP can be sterilized by all conventional methods.

PTFE, FEP and PFA tubes in heat exchanger applications

Heat exchangers are used in a wide range of applications in industries such as air conditioning, power plants, oil refineries and internal combustion engines. You may not know that you are familiar with heat exchangers. Take for example the radiator in your car. Heat exchangers keep your equipment cool and prevent overheating and malfunction. You may have seen someone open the hood of their car on the side of the road and smoke comes out as a result of a radiator failure.

Development and application of non-stick PTFE material

PTFE material has the smallest surface tension and inertness among solid materials and does not adhere to any substance. PTFE material has the lowest coefficient of friction, excellent self-lubrication, and also has excellent resistance to high and low temperatures, which makes it very widely used in applications such as the manufacture of non-stick pan anti-stick. PTFE is also used in rollers and other parts, as a guide, and as a material for the production of non-stick pans.

Polytetrafluoroethylene ---- raw material performance

Polytetrafluoroethylene (F4, PTFE) 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 - can resist aqua regia and all organic solvents; weather resistance - The best aging life in plastic; high lubrication - with the smallest coefficient of friction in plastic (0.04); non-stick - with the smallest surface tension in solid materials without adhesion to any material; non-toxic - with physiological inertia; excellent electrical properties, is the ideal C-class insulation material.
