PTFE skived sheet is manufactured by a unique process which provides a high level of fibrillation to overcome the creep relaxation and cold flow problems associated with standard skived PTFE sheets. It is produced from virgin PTFE resin filled with hollow-glass-micro -spheres. AS3302 is suitable for service with a wide variety of aggressive fluids, including hydrocarbons, acids and caustics, solvents, water, steam, hydrogen-peroxide, refrigerants, etc. It has excellent mechanical strength and high stress retention value. The high compressibility of PTFE skived sheet makes it particularly suitable for use with stress sensitive and/or fragile flanged joints, e.g. glass, ceramics, plastic, etc. The excellent malleability of it makes repairing of small damages and/or irregularities of the sealing area (flange surface) unnecessary. AS3302 is quick and simple to install. The used gasket can be removed easily and without residue.
