Description

Overview

Vespel SP-3 Natural Round Rod Overview

Vespel SP-3 is a high-performance polymer specifically formulated for use in vacuum and cryogenic conditions. Unlike other grades of Vespel, SP-3 is filled with 15% molybdenum disulfide (MoS₂), making it particularly suitable for low-friction and wear-resistant applications in non-lubricated environments. This grade is ideal for applications that require long-term performance in extreme conditions, where both heat and wear resistance are crucial.

  • Excellent heat resistance
  • Low surface friction with added MoS₂
  • Great chemical resistance
  • Highly creep-resistant
  • Outstanding dimensional stability at a wide range of temperatures
