Description


What is PAI?

 
Polyamide-imides are thermoplastic amorphous polymers that possess exceptional mechanical, thermal, and chemical- and wear-resistant properties. They are inherently nonflammable, have outstanding electrical properties, and possess enormous temperature stability from cryogenic to 300°C. These properties place polyamide-imides at the top of the price and performance pyramid with polyketones and polyimides. Polyamide-imides enjoy, as the name suggests, a positive synergy of properties from both polyamides and polyimides, such as flexibility, melt processability, elongation, dimensional stability, and toughness. Polyamide-imide polymers can be processed into a wide variety of forms, from injection- or compression-molded parts and ingots to coatings, films, fibers, and adhesives.
 

Characteristics:
 

  • High tensile and flexural strength over a wide temperature range up to + 225°C (450°F)
  • Excellent resistance to wear and creep under load (bearing grades)
  • Extremely low coefficient of thermal expansion
  • Excellent heat resistance in air (250°C)
  • High glass transition temperature of about 275°C
  • Excellent dimensional stability up to 250°C
  • Difficult to burn with very little smoke
  • Outstanding resistance to degradation by UV radiation
  • Good chemical resistance to many acids, alcohols, automotive fuels and oils, and halogenated solvents
  • Good electrical properties (not as good as fluorocarbons)
  • Good processability (can be extruded, thermoformed, injection and compression moulded)
