The long-term use temperature of such materials is between 150 ° C and 400 ° C. They retain good performance during long-term high temperatures, such as sliding friction and chemical resistance. Adding glass fiber, glass beads or carbon fiber to the material can further improve the thermal deformation resistance and rigidity of the material. The addition of additives such as PTFE, graphite and aramid fibers to the material can improve the sliding friction properties of the material, and the addition of metal fibers and carbon black can improve the electrical conductivity of the material.
