A Guide to PAI CNC Machined Parts: Properties, Applications and Design Considerations
What is PAI?
PAI (Polyamide-imide) is a high performance amorphous thermoplastic which is often used in place of metal components where there are weight restrictions.
PAI is considered the highest performing thermoplastic. It is available in a number of grades (such as carbon-fibre reinforced, glass-fibre reinforced, PTFE-filled, graphite-filled, unfilled, wear resistant, high strength, low friction) with varying characteristics.
