Plastic PEEK Round Bar 4" diameter Retail Price

About PEEK|Polyether ether ketone. The premium engineering plastic. Exceptional strength, stiffness, and temperature resistance (continuous use to 480°F). Chemical resistance rivals fluoropolymers. Machines beautifully with standard tooling at moderate speeds. The catch: it costs $50-100+ per pound. Used for aerospace components, medical implants, semiconductor equipment, and oil and gas downhole tools where nothing else can handle the environment. Compare to Ultem 1000 (similar temperature resistance, much cheaper) and Torlon 4301 (higher temperature capability).

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.
