Introduction to 1.
1. Name: Pfa tube, soluble polyethylene glycol propylene tube, transparent Teflon tube;
2. Pfa tube color:
Commonly used color: transparent, black; not commonly used color: yellow, brown, green, blue and other colors can be customized;
3. Pfa tube characteristics
Pfa tube common characteristics:
Use temperature:-200 degrees to 260 degrees;
Easy processing: can flanging, welding;
Aging resistance: can be exposed to ozone and sunlight for a long time without aging;
High transparency: low refractive index in all plastics, can be very intuitive to see the flow of the medium in the tube;
Corrosion resistance: Can withstand all strong acids, strong oxidants, strong reducing agents and various organic solvents except molten alkali metals, fluorinated media and those above 300 °.
Pfa tube not commonly used characteristics:
密度：2.16-2.20g/cm³
Volume resistance> 1 × 1018
Surface resistance> 2 × 1013
Arc resistance> 165 seconds no leakage
Low water absorption: water absorption <0.1%
Lower friction coefficient: the friction coefficient is small;
Surface non-stickiness: known solid material heads cannot adhere to the surface;
Incombustible: the air will not burn, in line with the strict requirements of the fire place;
Non-toxic: non-toxic and tasteless, with physiological inertia, no harm to people and the environment.
2. Pfa tube commonly used specifications are in stock: inner diameter * outer diameter (unit: mm) other specifications can be customized
Pfa tube metric system: 2*4 3*5 4*6 5*7 6*8 8*10 8*12 9*12 10*1212*14 14*16 16*18 18*20
Pfa tube inch system: 1/8 inch (1.6*3.2) 1/4 inch (3.96*6.35) 3/8 inch (6.35*9.525)
1/2 inch (9.5*12.7)3/4 inch (15.88*19.05) 1 inch (22.2*25.4)
Pfa pipe can be produced in specifications, with an inner diameter of 0.5mm to an inner diameter of 200mm and a wall thickness of 0.12mm to 3mm.

3. Pfa Tube FAQ
(1)pfa pipeline standard
In the international standard classification, pfa pipe refers to pipe parts and pipes.
In the Chinese standard classification, pfa pipes relate to piping accessories.
(2) The main difference between pfa tube and ptfe tube
1. Different in nature
PFA: a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene.
PTFE: Polymeric compound formed by polymerization of tetrafluoroethylene.
2, different characteristics
PFA characteristics: crystalline material, moisture absorption is small; poor fluidity, easy to decompose; translucent pellets, injection molding, extrusion molding.
PTFE characteristics: high temperature resistance; low temperature resistance; corrosion resistance; weather resistance; high lubrication; non-stick.
(3)pfa pipe connection mode
1. Threaded connection
2. Flaring connection; It is to heat the pipe and set it up.
(4)pfa pipeline brand
Teflon tube little sister home is the source of manufacturers, industrial brands to choose from.
4. Pfa tube main use
1, suitable for the production of corrosion-resistant parts, wear parts, seals, insulation parts and medical equipment parts.
2, high temperature wire, cable insulation, anti-corrosion equipment, sealing materials, pump valve bushing, and chemical containers.
3. Semiconductor manufacturing equipment, heat exchanger, steam piping, corrosive medium delivery pipe, wire and cable sheath, slot insulation pipe, all-inclusive fluorine-plastic O-ring pipe.
