Daelim H&L Plavis-G40 ISO 40% Graphite Filled Aromatic Polyimide Bearing
Categories: Polymer; Thermoset; Polyimide, TS

Material Notes: Isostatically Molded. Plavis-G-40: Graphite 40 wt% filled, Self lubricating grade with low thermal expansion.

General Plavis information for all grades:

PLAVIS polyimide has nitrogen bonded to 3 carbons is the critical part of the chain and imparts the plastic with remarkable features and benefits. PLAVIS is available as raw material or as molded parts, plates, and rods. PLAVIS isostatic molded rods have uniform properties in all directions.


  • One of the highest temperature plastics in the world with a continuous operating temperature of 300°C. Well suited for cryogenic conditions
  • Retains high tensile strength and modulus even at high temperatures. Will not crack or creep under load.
  • Lowest out-gassing of any plastic at 300°C. Will not contaminate vacuum chamber process or products.
  • Grades are available for use at 1 million psi-fpm PV limit with lubrication, 300,000 psi-fpm PV limit without lubrication. Stable friction level.
  • Filled grades resistivity is tailorable.
  • Machines like brass-tiny and intricate features can be produced without cracking. Can be lapped to mirror finish.
