DuPont™ Vespel® The high performance material for the toughest design problems. Vespel exhibits low wear and friction at high pressure and velocities, outstanding creep resistance, strength and impact resistance, lubricated or unlubricated performance, continuous operation at 500°F. with excursions to 900°F. NOT RECOMMENDED FOR STEAM SERVICE.

Vespel® SP1 – a material with superior wear and insulation properties, with operating temperatures from cryogenic to 300°C (570°F), great plasma resistance, plus a UL rating for minimal electrical and thermal conductivity

Vespel® SP21 – If insulation is less important than low-friction properties, then you're looking for graphite-enhanced SP-21. Automotive engineers love to use SP-21 for parts like thrust washers, bearings and seals – because the low-friction properties mean they work with or without lubrication.

Vespel® SP211 – Need a lower coefficient of friction than SP-21? Not as concerned about thermal and wear resistance? Then SP-211 could be your solution. With Teflon® PTFE as an additive, the coefficient of friction is further reduced, even without lubrication.

Vespel® SP22 – Designing with tight tolerances? SP-22 is the answer. When you've no room for error, SP-22's minimal thermal expansion and dimensional stability give you the freedom to create exactly what you've imagined.

Vespel® SP3 – Of course, working in vacuum and dry environments has its own challenges. Aerospace engineers have to worry about extra difficulties like outgassing. But SP-3 has proven high performance in aerospace applications, largely due to its ultra-low outgassing.
