Question: What is the minimum temperature rating for a PEEK oldham coupling disc?
Answer:We rate PEEK discs to -20 C because this is the guidance the manufacturer of the PEEK gives to us. When the low end of the temperature range is exceeded the material the material becomes brittle. Under a torque load this may cause the disc to fracture. PEEK is designed for use in high temperature or low outgas situations. When used in low temperature performance is largely dependent upon exposure time, temperature, and system requirements. The coupling may perform depending on where your application falls within these variables. However, it's generally not an application where we would recommend the use of a PEEK disc.
