PAI is an amorphous, high-performance thermoplastic polymer known for its exceptional temperature resistance, strong chemical resistance, and outstanding wear properties at temperatures of up to 275 °C. Also recognized under the trade name Torlon®, it is one of the highest-performing thermoplastics globally for melt processing.
Components made from this material offer excellent mechanical load-bearing capacity due to their high tensile and compressive strength. Additionally, polyamide-imide stands out for its combination of toughness and rigidity. The dimensional stability of finished parts is ensured by its high mechanical stiffness, low thermal expansion, and excellent heat resistance. Another advantage of this material is its remarkable strength in both tensile and compressive applications.
Various modifications of polyamide-imide are possible. Adding glass or carbon fibers enhances its strength and stiffness, while the incorporation of PTFE or other lubricants improves sliding properties and reduces friction, even in dry-running conditions.
PAI absorbs moisture, which can lead to dimensional changes in components. Moreover, it is sensitive to saturated steam at high temperatures. Overall, this polymer offers a well-balanced combination of mechanical, electrical, chemical, thermal, and tribological properties, making it ideal for demanding applications in harsh environments and high-temperature conditions.
