Ultra-high-performance specialty high-temperature plastics


Polyimide (PI)

  • Temperature resistance: Thermal decomposition temperature up to 600°C; long-term service temperature reaches 260–300°C; one of the most heat-resistant plastic categories available today.
  • Key characteristics: Combines excellent mechanical properties, chemical resistance, and electrical insulation; maintains stable performance in extreme high- and low-temperature environments.
  • Typical applications: Aerospace components, high-end electronic insulation parts, high-temperature resistant films, etc.


Polyether ether ketone (PEEK)

  • Temperature resistance: Long-term service temperature up to 250°C; short-term peak temperature resistance up to 300°C.
  • Key characteristics: Excellent comprehensive performance; combines high strength, wear resistance, and chemical resistance; good processability.
  • Typical applications: Precision mechanical parts, medical implants, aerospace structural components, etc.


Polytetrafluoroethylene (PTFE / Fluoroplastic)

  • Temperature resistance: Long-term service temperature up to 260°C; some modified fluoroplastics cover a temperature range of 150–260°C.
  • Key characteristics: Resistant to almost all acidic and alkaline media; excellent insulation properties; extremely low coefficient of friction.
  • Typical applications: Corrosion-resistant seals, non-stick coatings, high-frequency electronic insulation components, etc.
