PAI (Polyamide-imide)

PAI, also known as polyamide-imide, is an amorphous, thermoplastic high performance polymer with excellent mechanical properties. PAI plastic is used for the manufacture of components that can withstand heavy loads. This high performance plastic is often used for electronic/electrically insulating parts and applications in the medical sector.

PAI plastic properties 

Polyamide-imide is designated a high-performance plastic due to its unique combination of exceptional properties. Polyamide-imide is very strong and can withstand a wide range of temperatures. Furthermore, PAI is a very durable plastic, has low frictional resistance and is resistant to UV, gamma and X-rays.

  • Outstanding mechanical properties
  • Can withstand temperatures between -50°C to around 260°C
  • Highly durable
  • Heavy duty
  • Very low coefficient of expansion (0.025 mm/°C/metre)
  • Dimensionally stable
  • Low frictional resistance
  • Self-extinguishing
  • Resistant to UV, gamma and X-rays
  • Density: 1.60 g/cm3

Torlon – a PAI variant 

Torlon, a PAI variant, combines excellent mechanical strength, rigidity and creep resistance over a wide temperature range. It has an extremely low coefficient of expansion. Torlon plastics are ideally suited for applications which operate at high temperatures. This high level of resistance means it also has a high melting point.

Polyamide-imide plastic applications

Polyamide-imides are often an excellent choice for multi-requirement applications which must have high mechanical strength and durability, low creep and fatigue, all combined with excellent chemical properties. PAI plastic is suitable for plastic processes such as CNC machining and, to a limited extent, gluing. Examples of PAI applications are:

  • Dimensionally stable precision parts
  • Electrical components
  • Electronic components
  • Medical components
  • Wire-coating
  • Cleanroom/laboratory environments
