PAI is the highest performing, melt processable plastic. It has superior resistance to elevated temperatures and is capable of performing under severe stress conditions at continuous temperatures to 500°F (260°C). Parts machined from PAI provide greater compressive strength and higher impact resistance than most advanced engineering plastics. PAI has an extremely low coefficient of linear thermal expansion and its high creep resistance deliver delivers excellent dimensional stability over its entire service range. Popular extrusion and injection molding grades are offered as compression molded shapes.
