UHP Australia are also stockists of UHP PFA Tube.PFA, or perfluoroalkoxy, is well recognized for its ability to maintain mechanical integrity in extreme temperatures even when exposed to caustic chemicals. PFA comes in high purity versions that are SEMI F-57 certified, lending itself to critical fluid transport tubing applications that demand a very low level of extractible. This fluoro polymer possesses the ability to withstand temperature environments of up to 260°C/500°F and can be extruded in convoluted tubing forms that provide a highly flexible conduit. The qualities of PFA include excellent lubricity, clarity, flexibility, and chemical resistance. This versatility has led to PFA being a popular material selection in the semiconductor, chemical, oil & gas, aerospace, automotive, pharmaceutical, fibre optics and medical industries.
