What is a tetrafluorotube?
Tetrafluoroethylene pipe, the scientific name of polytetrafluoroethylene pipe (PTFE pipe), is a plastic pipe made of polytetrafluoroethylene resin through a special process. It is known for its excellent chemical stability, high temperature and low temperature resistance, low friction coefficient and electrical insulation properties, and almost does not react with all chemicals. Widely used in chemical, pharmaceutical, food processing, aerospace and other fields, as the transport of corrosive media, high purity fluid and wire and cable jacket and other purposes.
What is a PFA tube?
The full name of PFA tube is perfluoroalkoxy resin tube, which is an improved version of polytetrafluoroethylene, and the chemical name is tetrafluoroethylene - perfluoroalkoxy vinyl ether copolymer. Triflure PFA tubes inherit all the excellent characteristics of PTFE, and on this basis enhance the melting fluidity, so that it can be made into complex shapes by extrusion or molding. Its thermal stability and mechanical strength is better than PTFE, higher transparency, and can still maintain good toughness and creep resistance at high temperatures, suitable for semiconductor, nuclear industry, biomedicine and other fields of high temperature, high pressure, strong corrosion environment of pipe connection and parts manufacturing.
What is the difference between tetrafluorotube and PFA tube?
What is the difference between tetrafluorotube and PFA tube?
Although PTFE tubes and PFA tubes belong to the same fluoroplastic family, there are differences in specific properties and applications:
1.Processing performance: PTFE material has low plasticity, generally need to fill, sintering or expansion processing; Due to the improvement of molecular structure, PFA has better melting processing performance, and can be formed by extrusion, injection molding and other ways.
2. Temperature range: Both show excellent temperature resistance, but the use of triflure PFA tube temperature range is usually wider, long-term operating temperature limit can reach more than 260 ° C, short-term can even reach more than 300 ° C, while PTFE tube although also high temperature resistance, but the long-term use of the limit temperature is relatively low.
3. Physical properties: PFA tube compared with PTFE tube, its mechanical properties such as tensile strength, elongation, stress relaxation and other aspects are more excellent, better flexibility, not easy to crack, especially under high temperature conditions, PFA tube performance attenuation is smaller.
4. Transparency and cleanliness: PFA tubes are more transparent than PTFE tubes, which is especially important for applications where the internal fluid state needs to be observed. At the same time, PFA tubes in areas with high cleanliness requirements, such as semiconductor production, biomedicine, etc., its surface smoothness and pollution-free characteristics can better meet the needs.
5. Cost and market positioning: in view of the superior performance of PFA tubes, its cost is often higher than PTFE tubes, so it is mostly used in applications with higher performance requirements or special environmental conditions, and PTFE tubes are cost-effective in many conventional anti-corrosion, insulation and sealing.
