PFA Powder (Perfluoroalkoxy)
PFA (perfluoroalkoxy) powder is supplied in fine coating and molding grades for semiconductor, high-purity fluid handling, and reactor lining applications. It combines PTFE-level chemical resistance with full melt-processability and a continuous service temperature up to about 260°C. Commercial coating powders typically range from about 25 to 110 µm depending on grade; grades and particle size are confirmed at time of quotation.
