The ultimate temperature resistant polymer

Polyimide bolts or Vespel® bolts are made from an advanced temperature resistant polyimide resin. Polyimide bolts or Vespel bolts offer a unique balance of mechanical, thermal, and chemical properties for outstanding performance in a variety of demanding applications such as automotive, machinery, industrial equipment, aerospace, and semiconductor equipment.

Polyimide bolts or Vespel bolts also have the unique combination of properties such as excellent mechanical strength and toughness, exceptional radiation resistance, robust chemical resistance to many solvents, a low coefficient of thermal expansion, excellent creep resistance and flame retardance.

Polyimide bolts or Vespel bolts are available in both metric and standard sizes. Contact us to learn more about polyimide bolts or Vespel bolts properties and availability.
