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. 

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.
