What is ptfe hose | BESTEFLON

Have you heard about PTFE material and PTFE hose? Well, let's see if we can answer some questions about it.

Polytetrafluoroethylene (polytetrafluoroethylene) is abbreviated as PTFE, commonly known as "plastic king", and its trade name is Teflon. In China, due to pronunciation, "TEFLON" is also known as Teflon, all of which are transliteration of Teflon. Polytetrafluoroethylene is known as the "king of plastics", the father of fluororesin Roy Planck 1936 DuPont company in the United States began to study the substitutes of Freon. They collected some tetrafluoroethylene and stored them in cylinders for the next experiment the next day. However, when the cylinder pressure relief valve was opened the next day, no gas overflowed. They thought it was a leak, but when weighing the cylinder, they found that the cylinder did not lose weight. They saw through the cylinder and found a lot of white powder, which is polytetrafluoroethylene. They found that polytetrafluoroethylene has excellent properties and can be used as anti melting sealing gasket for atomic bombs and shells. Therefore, the U.S. military kept the technology secret during World War II. It was not until the end of World War II that it was declassified and industrialized in 1946.Related Searches: PTFE lined hose, PTFE corrugated hose

Polytetrafluoroethylene can be formed by compression or extrusion; it can also be made into water dispersion for coating, impregnation or fiber. Polytetrafluoroethylene (PTFE) is widely used in the industries of atomic energy, national defense, aerospace, electronics, electrical, chemical engineering, machinery, instruments, instruments, construction, textile, metal surface treatment, pharmaceutical, medical, textile, food, metallurgy and smelting industries, etc., which makes it an irreplaceable product.

PTFE is the abbreviation for polytetrafluoroethylene - it's a long word, but long must mean it's good! The trademark name of polytetrafluoroethylene is the most common name of polytetrafluoroethylene.

Why do polytetrafluoroethylene (PTFE) hose be used in inkjet pipe of 3D printer, feeding pipe of coffee machine, water cooling system pipe and brake pipe system?

1) PTFE tube has high chemical stability and can withstand the action of all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acid, strong base, strong oxidant, reducing agent and various organic solvents. It is widely used in conveying various harsh fluids.

2) It can be used for a long time in the range of - 80 ℃ - + 280 ℃. It can work at freezing temperature without embrittlement and melting at high temperature.

3) The outstanding non viscosity and anti viscosity is excellent, and the inner wall of the pipe does not adhere to colloids and chemicals, so it will not form a dirt layer in the pipe.

4)  Excellent electrical insulation performance Teflon is a highly non-polar material with good dielectric properties, high resistance and dielectric constant of about 2.0, which is the smallest among all electrical insulation materials, and the change of temperature and frequency has little effect on them.

5) Excellent aging resistance and radiation resistance, can be used outdoors for a long time.

6) Excellent thermal stability, Teflon has a very valuable incombustibility, its oxygen limit index is above 95, it can only melt in the flame, does not generate droplets, and can only be carbonized.

7) High softness and bending resistance.

8) moisture resistance: the surface of Teflon film is free from water and oil, and it is not easy to be stained with solution during production operation. If there is a small amount of dirt adhered, it can be removed by simple wiping. It has the advantages of short downtime, saving man hour and improving work efficiency.

9) Wear resistance: excellent wear resistance under high load. Under certain load, it has the advantages of wear resistance and non adhesion.

Polytetrafluoroethylene hose has some advantages over ordinary rubber lined hose.

First, polytetrafluoroethylene (PTFE) hose acts as a vapor barrier, which is not sticky at the same time of high temperature resistance, and can meet the requirements of these machines and equipment for its use of pipes.

Second, PTFE lined hose has the highest chemical resistance and supports a range of automotive fluids that ordinary rubber cannot provide, the most common being gasoline blends containing ethanol. Ordinary rubber hose will decompose when exposed to this kind of gasoline and eventually degrade to the extent that it may start to leak or inject fuel, which is quite dangerous.

Third, Teflon lined hose has a very high temperature resistance - in fact, the operating temperature range of hose sold with PTFE tubes is - 65° C to + 260 ° C. It is very suitable for use on these devices.

Fourth, Teflon tube Teflon hose has very high working pressure, again ensuring that you can use it for all types of automotive and hot rod applications. An6 size for 2500psi, an8 size for 2000psi, even the most demanding applications, its pressure is more than enough.

other? Yes, in fact - braided in our hose ensures a long service life and sharp appearance for installation. When you choose stainless steel, it has a sharp look and gives you a piping engineering professional hot rod feel. Black nylon if you want a softer look. But you know, black nylon still has a stainless steel lining. We just need to coat the stainless steel with black nylon to get a different look.

Now available - blue and red Nylon Braided PTFE lined hose hot rod fuel hose size an6.

So PTFE hose sounds good - what's wrong with it?

In general, PTFE tube can replace most of the rubber tube scenarios. The only disadvantage of PTFE tube is that its flexibility is not as good as that of rubber tube. However, the bellows series of PTFE tube has certain flexibility, which can solve this small defect relatively. But there are some things you need to know.

1 - for PTFE lined hose, you need to use the appropriate fittings from the same manufacturer to ensure good sealing on the fittings. Since the seal is created with a ferrule instead of an insert on the rubber hose, more care needs to be taken when cutting. For more information, see our installation instructions.

The bending radius of the 2-ptfe hose is more stringent because it will be easier to kink if it exceeds the specification. For more information, see our article on bend radius.

It's not the case with hot rod fuel hose, but if you shop around, PTFE hose is usually more expensive than rubber lined hose - the price of hot rod fuel hose is very positive, often several times the price of rubber hose, and will last for a long time.
