VESPEL-POLYIMIDE PARS & SHAPES

Vespel® is a family of high-performance polyimide-based materials manufactured by DuPont. Known for its ability to maintain exceptional mechanical, thermal, and chemical properties in extreme conditions, Vespel® is an industry leader for demanding applications in aerospace, automotive, industrial, semiconductor, and medical sectors.

Key Features
Extreme Temperature Resistance
  • Operates from cryogenic temperatures up to 300°C (572°F) continuously.
  • Can withstand short-term excursions beyond 400°C (752°F) without significant loss of properties.
Low Friction & Superior Wear Resistance
  • Offers outstanding tribological performance in both dry and lubricated environments, reducing wear on interacting components.It has high (Pressure x Velocity)PV value.
  • Self-lubricating properties make it ideal for applications where conventional lubrication is not feasible.
High Strength and Durability
  • Retains mechanical strength under high loads and temperatures.
  • Exhibits excellent creep resistance and dimensional stability over time.
Chemical and Environmental Stability
  • Resistant to fuels, solvents, oils, and most chemicals, ensuring long-term performance in harsh environments.
  • Non-corrosive and unaffected by UV radiation.
Electrical Insulation
  • High dielectric strength and excellent insulating properties make it suitable for electronic and electrical applications.
Lightweight
  • Reduces weight by up to 50% compared to metals, contributing to energy savings and efficiency.
Temperature resistance
Vespel® SP and SCP parts resist temperatures from cryogenic (-196°C) to 350°C, with excursions to 480°C, going beyond the operating window of PEEK and most engineering polymers. Where extreme temperature resistance is required, SCP grades are designed to operate successfully at elevated temperatures, with excursions as high as 650°C.
Applications
Aerospace Industry
  • Components like bushings, thrust washers, seals, and thermal insulation in jet engines.
  • Critical parts for satellites and spacecraft, ensuring reliability in extreme space environments.
Automotive Industry
  • Used in fuel systems, emissions control, bearings, and valve seats to improve efficiency and durability.
  • Helps reduce wear and friction in engines and transmission systems.
Semiconductor Manufacturing
  • Ideal for wafer-handling equipment due to its low outgassing, thermal stability, and resistance to chemical etching.
Industrial Applications
  • Bearings, rollers, and seals in high-wear industrial machinery.
  • Components exposed to high temperatures or corrosive environments.
Medical Equipment
  • Precision components in surgical instruments and diagnostic devices.
  • Offers excellent biocompatibility and reliability.
