semitransparent teflon, what are the four fluorine tube?
With the progress of science and technology, more and more industries need some catheters made of polymer materials. What are these catheters? Teflon tube sister will take you to know briefly.
1. PTFE tube
Polytetrafluoroethylene [PTFE,F4], is one of the best corrosion resistance materials in the world today, so it is known as the "plastic king. It can be used in any kind of chemical medium for a long time, PTFE seals, gaskets, gaskets. PTFE seals, gaskets, gaskets are made of suspension polymerization PTFE resin molding.
Features: temperature resistance of 260 degrees Celsius, non-sticky, good insulation, resistance to almost all chemicals (except fluorine and alkali metals at high temperatures), with the lowest coefficient of friction.

2. FEP tube
FEP is fully known as Fluorinated ethylene propylene, English trade name: Teflon *, FEP, is a class of chemical substances. Composition: FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene. Melting point: 304 ° C., density: 2.15g/cc (grams/cubic centimeter). Application FEP can be applied to soft plastics, the tensile strength, wear resistance, creep resistance is lower than many engineering plastics.
Features: easy to weld, can be reshaped, -200°C to 200°C working temperature-FEP at low temperature still maintain soft, corrosion-resistant chemical properties, good UV resistance, physiological inertness, more suitable for the medical industry, high transparency, can observe the internal fluid transport

3. PFA tube
PFA is the abbreviation of English Polyfluoroalkoxy, the Chinese name is soluble polytetrafluoroethylene. PFA plastic is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melt cohesiveness is enhanced, the solution viscosity is reduced, and the performance is unchanged compared with PTFE.
Features: the use of temperature up to 260 degrees, can be welded, easy to reshape and reprocess, good anti-permeability, airtight effect, corrosion resistance, physiological inertia, can be used in the medical industry, high purity grade for ultra-pure gas delivery, high permeability color, can detect the internal fluid
