The 3R8200 is produced from virgin PTFE resin filled with micro spheres of silica. This unique process of fabrication provides the Tealon® a high level of fibrillation to overcome the creep relaxation and cold flow problems associated with mechanical grade (3R810) and virgin grade (3R812) PTFE sheets.


It is suitable for services with high pressures and temperatures, especially in chemical processing and hydrocarbon plants in strong acids (except hydrofluoric), solvents, hydrocarbons, water, steam and chlorine.
