PAI (POLAMIDE IMIDE)

PAI (polyamide-imide) is a resin that is exceptionally strong and stiff. It’s frequently utilised in high-temperature settings where other thermoplastics’ mechanical qualities would be compromised. PAI is a dimensionally stable material with a low coefficient of thermal expansion (CTE), making it a good choice for applications requiring close precision machining. It comes in a number of different formulations.

PAI is known across the globe as the highest performing melt-processable thermoplastic material. PAI keeps its strength and rigidity at temperatures up to 500 degrees Fahrenheit (260 degrees Celsius). Its maximum growth rate is 500 degrees Fahrenheit (260 degrees Celsius). In bearing grades, PAI Manufacturer in India that offers good wear resistance.

PAI IS WIDELY USED FOR:

  • Semiconductor machinery parts
  • Chip test sockets
  • Aerospace components
  • Electrical connectors
  • Bearings and bushings
  • Bearing cages
  • Pump and valve parts
  • Seals

PERFORMANCE CHARACTERISTICS:

  • Strong and stiff
  • Performs well at elevated temperatures
  • Extremely low thermal expansion
  • Excellent electrical insulating properties (electrical grade)
  • Outstanding bearing and wear properties (bearing grade)
  • Good resistance to many common solvents, fuels, and acids
