A great innovation in compression packing was the development of a new material class by Ritchie Snyder of W.L. Gore & Associates in 1981. He envisioned a single material that would allow for broad standardization across a wide
range of applications. It would deliver the chemical compatibility of polytetrafluoroethylene (PTFE) and graphite, with the mechanical strength of the then newly expanded PTFE material (ePTFE).
Over the next 35 years, many pulp and paper, chemical, mining and power companies have standardized their plants with this new material class of ePTFE/graphite packing fiber.
