Plastic Torlon 4301 Round Bar 1" diameter Retail Price

About Torlon 4301|Polyamide-imide (PAI). The highest-performing unfilled thermoplastic you can machine. Continuous use to 500°F with strength retention that embarrasses most plastics at room temperature. Used for jet engine components, semiconductor equipment, and anywhere you'd use metal but need the weight savings or chemical resistance of plastic. Very expensive ($100+ per pound). Machines with carbide at moderate speeds. Compare to PEEK (similar temperature range, less strong, cheaper) and Vespel (polyimide, even higher temperature but essentially unmoldable, machined only).

About Round Bar|The default starting stock for lathe work. It gets turned, bored, and parted into shafts, pins, bushings, spacers, and just about anything round.
