There are two types of transparent Teflon tubes. FEP (polyperfluoroethylene propylene), PFA (soluble polyperfluoroethylene propylene). There are several types of materials for these two types of pipes. Brand-new materials, imported materials, sub-brand materials, and different raw materials. The price of transparent Teflon pipes is also different. When the price difference is too large, remember to understand what raw materials are.

First introduce us to FEP (polyperfluoroethylene propylene) transparent Teflon insulation sleeve .

Teflon pipe, also known as FEP

Common Features:

Operating temperature: -200 degrees to 200 degrees

Ease of processing: can be flanged, soluble, sealable, and weldable

Aging resistance: long-term exposure to ozone and sunlight without aging

High transparency: the refractive index is low in all plastic guesses, and the flow of the medium in the pig can be viewed directly.

Corrosion resistance: It can accept the effects of all strong acids, strong oxidants, strong reducing agents and various organic solvents except for molten alkali metals, fluorinated media and above 300 °.

PTFE has good electrical insulation and chemical stability similar to PTFE, hardness and tensile strength are slightly improved compared to PTFE, and public welfare is greatly improved. The melting temperature of the crystalline phase (280 ℃) is about 50 ℃ lower than that of polytetrafluoroethylene, but it can still be used in the temperature range of -85 ℃ ~ 204 ℃ for a long time, and it has better cold resistance than polytetrafluoroethylene at normal temperature. Fluidity, but the coefficient of friction is slightly lower.

Polyperfluoroethylene propylene has the same precious characteristics as polytetrafluoroethylene, but also has the good processing function of thermoplastics, which makes it replace F-4 material in some aspects, and has been widely used.
