PTFE-based materials are widely applied for seals and are chemically compatible with almost all media and tolerate a wide temperature range. The weaknesses of virgin PTFE are the wear and deformational properties; which however can be improved significantly by incorporating suitable fillers. A range of PTFE-based seal materials exists on the market today; each with their strengths and short-comings. The idea of a universally applicable seal material is probably unrealistic. However; this paper reports the outcome of a project aimed at developing a new PTFE-based material (Turcon M12); which covers a significantly wider range of applications compared to existing PTFE materials. Shown results compare this new material with traditional PTFE seal materials using different types of hydraulic test-rigs; operating conditions and media. The results show that the new PTFE material matches the good extrusion; wear and deformational properties of PTFE/Bronze while being able to cope with conditions of starved lubrication without damaging the counter surface
