There are two types of transparent Teflon tubes. FEP (polyfluoroethylene propylene), PFA (soluble polyfluoroethylene propylene). Attention, there are several kinds of materials for these two kinds of tubes, new materials, imported materials, and sub-brand materials. The raw materials are different. The price of transparent Teflon tubes is also different. You can get the price for each price. If you make an inquiry The price difference is too big when shopping around, but remember to understand what raw materials are.
First, I will introduce FEP (polyfluoroethylene propylene) transparent Teflon tube.
Polyperfluoroethylene propylene pipe, also known as FEP
Introduction of common features:
Operating temperature: -200 degrees to 200 degrees
Ease of processing: can be flanged, soluble, sealable, and weldable
Aging resistance: can be exposed to ozone and sunlight for a long time without aging
High transparency: the refractive index is low among all plastics, and the flow of the medium in the pig can be viewed directly
Corrosion resistance: It can withstand the action of all strong acids, strong oxidants, strong reducing agents and various organic solvents except molten alkali metals, fluorinated media and those above 300°.
As you all know, the two most popular fluoroplastic pipes on the market are PTFE and polyperfluoroethylene propylene.
Polyperfluoroethylene propylene has excellent electrical insulation and chemical stability similar to PTFE. Its hardness and tensile strength are slightly higher than those of PTFE, and its public welfare is greatly improved. The melting temperature of the crystalline phase (280℃) is about 50℃ lower than that of PTFE, but it can still be used in the temperature range of -85℃~204℃ for a long time, and it has better cold resistance than PTFE at room temperature. Fluidity, but the coefficient of friction is slightly lower.
Polyperfluoroethylene propylene not only has valuable properties similar to PTFE, but also has excellent processing properties of thermoplastics, so that it can replace F-4 materials in some aspects and has been widely used.
