High temperature nylon refers to a nylon material that can be used in an environment above 150 °C for a long time.
The melting point is generally between 290 °C and 320 °C.
Generally, the temperature of glass fiber modification is sufficient for thermal deformation to exceed 290 °C, and it can be used in a wide temperature range and high humidity environment.
Maintaining excellent mechanical properties, the current mature industrialized high-temperature nylon varieties include PA46, PA6T, PA9T and PA10T
