Glass Micro-Spheres Filled PTFE Sheets
Champion Jointing Style AF RGS is a high performance biaxially orientated sheet sealing material containing PTFE and hollow glass microspheres.manufactured from high quality PTFE resin though unique process, eliminating the problems of creep relaxation and cold flow associated with normal (skived or moulded PTFE Sheets).This grade is produced in Blue colour.
Champion Jointing AF RGS continuously providing best performance in applications with high mechanical requirements at high temperatures and pressures hence is used as gasket for universal applications. This gasket material features excellent acidic and alkaline resistance and versatility in steam applications. It is primarily used in the chemical, the petrochemical and the maritime industry.
Suitable for use in alkali, acid and chlorine service, can be used for all concentrations of sulphuric acid, hot and cold potable water services. pH range is 0-14.
