PCTFE seal for high pressure and high flow valve
SPN manufactures custom PCTFE seals for high pressure and high flow valves. Specialized in the manufacturing of sealing components, SPN works with PCTFE to produce seals that meet your specifications in every way. Suitable for gases – nitrogen, acetylene, oxygen, etc. – industrial quality, these seals can be installed on high pressure holders, die-cast brass bodies and on cylinders and 200 bar frames among others. They can also be installed on anti-whipping, anti-tearing cables and high pressure connection hoses.
In high-performance plastics, PCTFE or polychlorotrifluoroethylene is one of the most popular materials used by manufacturers in the cryogenic and aeronautics sectors and by equipment manufacturers. This fluorinated polymer has many qualities, namely high chemical stability, low gas permeability and very high resistance to low temperatures.
PCTFE differs from PTFE by its composition incorporating an additional chlorine atom. With a flammability rating of V0 according to UL94, PCTFE also benefits from excellent flammability resistance. This polymer also retains good dimensional stability, even at temperatures ranging from -240 °C to + 150 °C. In addition to being impermeable to gas, polychlorotrifluoroethylene or PCTFE remains intact in contact with certain antioxidants and chemicals thanks to its hydrogen-free formulation.
In addition to PCTFE, SPN works with other high performance materials such as PTFE, PFA and FEP. Contact our team now.
