PAI

HPMs – High-performance materials

PAI

Polyamide-imide is a thermoplastic with excellent performance capabilities and good ability to withstand loading, even at very low temperatures. Parts made from PAI can be used as a replacement for metal components in exacting environments in which lighter parts are required. We deliver PAI as plastic sheets and rods.
