FEP tube full name of polyethylene glycol propylene tube, also known as F46 tube, transparent Teflon tube. FEP tube is a soluble fluoroplastic tube, adhering to the fluoroplastic
Most of the characteristics of the tube are easier to form, can produce longer continuous lengths, and can also produce various forms.FEPThe tube has high transparency,
Internal fluid transport can be observed.

FEP
FEPFull nameFluorinated ethylene propylenewhich translates as fluorinated ethylene propylene copolymer (perfluorinated ethylene propylene copolymer) English Commodities
Name:Teflon* FEPIt is a kind of chemical substance.FEPare tetrafluoroethylene andHexafluoropropyleneCopolymerized.FEPThe crystalline melting point is304 ℃, density
For2.15g/CC(grams/cubic centimeter).FEPcan be appliedsoft plastic,Its tensile strength, wear resistance, creep resistance is lower than many engineering plastics.
PTFE
PTFE (F4,PTFE) has a series of excellent performance: high temperature resistance-long-term use temperature 200~260 degrees, low temperature resistance-in -100
It is still soft when it is in degrees; corrosion-resistant to aqua regia and all organic solvents. Weather-resistant-best aging life in plastics; high lubrication-with plastic
Minimum coefficient of friction (0.04); non-sticky-has the smallest surface tension in solid materials without adhering to any substances; non-toxic-has raw.
It is an ideal C- class insulation material with excellent electrical properties.

2. FEPTubewithPTFEDifferent pipe characteristics
FEP
1,Use temperature:-200 degrees to 200 degrees
2,High transparency for monitoring internal chemical delivery.
3,Low friction.
4,Excellent chemical resistance, chemically inert to most industrial chemicals and solvents.
5,can be manufactured continuously,The FEP tube can be manufactured with a continuous length of 500 meters, or even longer.
6,Can be welded,Due to its solubility, FEP pipes can be welded at the joint connection.
PTFE
1,Use temperature:-200 degrees to 260 degrees
2,Easy processing: can flanging
3,Aging resistance: can be exposed to ozone and sunlight for a long time without aging
4,Corrosion resistance: able to withstand in addition to molten alkali metals, fluorinated media and higherBeyond 300 °.ByThere are strong acids, strong oxidants, strong also
The role of the original agent and various organic solvents.
