Expanded PTFE is manufactured by expanding 100% virgin PTFE using a proprietary process that produces a uniform and highly fibrillated microstructure with equal tensile strength in all directions. The lightweight ePTFE exhibits characteristics significantly different than any other type of PTFE sheet manufactured. This sheet is much softer, more flexible, and easier to compress than skived or restructured PTFE sheets and thus conforms easily to irregular and rough surfaces. Even though the sheet is soft and easy to compress, when PTFE fibers are expanded in a controlled manner, they become extremely strong. These high strength, biaxially-oriented fibers make ePTFE the PTFE product with the lowest creep and cold flow. Therefore, ePTFE can be safely used in temperatures that might cause other styles of PTFE to creep, lose bolt load, and leak. Expanded PTFE gasketing products are available flat sheets, rectangular profile sheet-like gasket tapes, and form-in-place joint sealant.

Teadit 2235 -- Steam Valves
Steam service requires a material that can withstand high temperatures for an extended period without degradation, and valves require a packing material that is robust and pressure resistant without damaging the valve stem. A major petrochemical plant was having problems with high temperature, superheated steam leaking from valve stems throughout the facility. Leakage of such high temperature steam posed a significant safety risk for all those on site and the leakage was also negatively influencing the quality of the process. In addition, the steam leakage was causing extremely high maintenance costs due to down time. Steam valves can prove to be a challenging application to create an effective, long term seal.
Teadit 2002 – Paper Refiner
A major paper manufacturer was not achieving their desired level of performance from their previous packing material on their refiner. A common challenge in pulp and paper applications, such as this, is that the media is often abrasive which can be difficult for mechanical packings and requires a packing material with more mechanical strength to resist wear from the media. Another common challenge in certain rotating equipment applications is that a high amount of heat is generated due to friction between the packing and the shaft. The thermoset packing material is not ideal for handling abrasive types of medias and required a high amount of flush water in order to dissipate the friction heat, as it does not have as high of heat dissipation properties as other types of packings.
