The 3R8000 is produced from virgin PTFE resin filled with hollow glass micro spheres. 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 a wide variety of aggressive fluids, including hydrocarbons, acids and caustics, solvents, water, steam, hydrogen-peroxide and refrigerants. The high compressibility of 3R8000 makes it particularly suitable for use with stress sensitive and/or fragile flanged joints.
