Polyimide Vespel Metric Flat Washers - ISO 7089

SKU: PIWAM3
PI Material Data Sheet
Regular price $22.45 inc. VAT

Polyimide Vespel is engineered for extreme operating environments to deliver outstanding thermal stability, wear resistance, and long-term mechanical performance. Furthermore, these washers offer outstanding creep resistance, low outgassing characteristics, and excellent wear properties. Their ability to perform under extreme temperatures and harsh operating conditions makes them an ideal choice where conventional engineering plastics and metal washers may be unsuitable.

Polyimide Vespel flat washers are widely used in aerospace systems, semiconductor equipment, vacuum chambers, medical devices, laboratory apparatus, and high-temperature industrial applications requiring ultra-high-performance non-metallic fastening components.
