PFA welding rods and PFA welding strips are both types of welding materials used in the process of welding PFA (Perfluoroalkoxy) materials. PFA welding rods are cylindrical in shape and typically have a diameter of 2-5mm. They are made of PFA material and are used to join PFA materials together by melting the rod and fusing it with the PFA material being welded. PFA welding strips, on the other hand, are flat and rectangular in shape with a thickness of 1-2mm. They are also made of PFA material and are used to fuse PFA materials together by melting the strip and fusing it with the PFA material being welded. Both PFA welding rods and strips are known for their excellent chemical resistance, high temperature resistance, and low coefficient of friction. They are commonly used in the chemical processing, semiconductor, and medical industries for welding PFA components such as pipes, valves, and fittings. Welcome to contact RANA for more details.
