The XRFLON R series sealing materials are high-performance modified gaskets made of 100% pure polytetrafluoroethylene filled with various high-quality fillers. The R series has developed a highly fibrous structure through repeated rolling. The more uniform mixing of inorganic fillers with PTFE resin ensures that the R series possesses more stable physical and mechanical properties. The XRFLON R series does not suffer from the cold flow problem associated with pure PTFE and conventional cut PTFE, nor from the issue of inadequate hardness found in PTFE materials modified with other fillers. I. XRFLON R series sealing materials >> Introduction XRFLON R204 sealing material is a high-performance modified gasket made from polytetrafluoroethylene resin filled with hollow glass microspheres. Glass microbeads are used for filling and modification to enhance the material’s ability to compensate for flange irregularities or surface defects. R204 is commonly used for low-load bolt sealing, as well as in various corrosive liquids and pipe flanges. XRFLON R206 sealing material is a high-performance modified gasket made from polytetrafluoroethylene resin filled with high-purity silica. R206 boasts excellent chemical resistance and can be used in most chemical environments, maintaining outstanding sealing performance even in highly acidic conditions. XRFLON R208 sealing material is a high-performance modified gasket made from polytetrafluoroethylene resin filled with high-quality barium sulfate. R208 boasts excellent sealing properties as well as high chemical and mechanical resistance. It can be applied to most chemical environments, offering excellent sealing performance even in highly alkaline conditions. II.
