What is Polyamide-Imide (PAI)?

Polyamide-imide (PAI) is a premium engineering thermoplastic that combines the superior properties of polyamide and polyimide. Its standout features include high mechanical strength, thermal stability, and exceptional chemical resistance. PAI retains its rigidity and structural integrity at temperatures up to +275°C, making it indispensable in industries requiring materials that perform under extreme conditions. Its chemical resistance includes strong acids and many organic solvents, and its flame-retardant properties enhance its safety profile.

Applications of Polyamide-Imide (PAI)

Aerospace Industry

PAI is used to manufacture components such as fasteners, bearing retainers, and support washers. Its ability to withstand high temperatures and mechanical stresses ensures reliability in critical aviation systems.

Machinery and Manufacturing

Gears, bushings, and seals in industrial equipment benefit from PAI’s excellent wear resistance and dimensional stability, even under heavy loads and high temperatures.

Electrical and Electronics

In the electrical sector, PAI is essential for motor components and insulation materials due to its non-conductive properties and resistance to thermal expansion.

Semiconductor Industry

PAI is widely applied in the production of semiconductor testing equipment, thanks to its precision and durability in handling sensitive electronic components.

Oil and Gas

PAI components are integral to oil and gas extraction devices, offering resistance to harsh chemicals and extreme conditions.
