PTFE Tube Chemical stability

[Excellent features]

High chemical stability, can withstand all the strong acid, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acids, strong alkali, strong oxidants, reducing agents and the role of various organic solvents. Very suitable for high purity chemical feeding use.

②. Extensive use of temperature range, can be used in the range of -73 ℃ - + 260 ℃.

③ prominent non-sticky, excellent anti-stick, the tube wall is not easy to adhere to colloids and chemicals.

④. High flexibility, resistant to bending.

⑤. Excellent anti-aging and anti-radiation properties can be used for a long time outdoors,

⑥. Excellent thermal stability, with a very valuable, the limited oxygen index of 95 or more, can only melt on the flame, do not generate droplets, and ultimately can only be carbonized.

⑦. Excellent electrical insulation properties, PTFE is a highly non-polar material, with good dielectric properties, great resistance, dielectric constant of about 2.0, in all electrical insulation material is the smallest, and the temperature and frequency changes They basically do not affect.

⑧. Part of the tube with high transparency, easy to observe the internal fluid condition.

Polytetrafluoroethylene pipe in the field of corrosion known as the "plastic king", and can become a pipeline anti-corrosion industry, "strong", first of all from its own superior physical and chemical performance analysis. Teflon tube mechanical properties:

Teflon friction coefficient is very small, only 1/5 of polyethylene, which is an important feature of the appearance of perfluorocarbon. And because the fluorine - carbon chain intermolecular force is very low, so polytetrafluoroethylene has a non - sticky. Polytetrafluoroethylene in the -196 ~ 260 ℃ wide temperature range are maintained excellent mechanical function, perfluorocarbon polymer is one of the characteristics of the brittle at low temperatures.
