Bal Seal Engineering, Inc., with offices in Foothill Ranch, California and Colorado Springs, Colorado, has expanded its line of seal materials to include P78, a high-temperature, high-performance thermoplastic, and P240, a lubricated, fiber-reinforced version of P78. The company says the properties of the new materials make them ideal for use in the chemical processing and petrochemical industries and in applications requiring excellent wear resistance at extremely high temperatures.
The materials are suitable for applications such as valve seats, electrical connectors, bearing seals and bushings. P78 is particularly suitable for use in simple support rings whereas P240 is ideal for high-temperature seals in addition to support-ring applications where the ring may come into contact with a dynamic part. Both materials are suitable for rotary or reciprocating applications.
The company says it added the new materials to its offering in answer to a growing demand for sealing options that could withstand the increasingly extreme temperatures in petrochemical and chemical process applications.
