Need a material with superior wear and insulation properties? Semiconductor manufacturers often find our SP-1 products useful in their production processes. And, with operating temperatures from cryogenic to 300°C, great plasma resistance, plus a UL rating for minimal electrical and thermal conductivity, it isn’t hard to see why.

SP-21 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.

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

If you need a material that can supply low-frictional properties and the benefits of even a longer life than our SP-21, look to SP-214. It's an S-line solution designed to withstand some of your harshest conditions, in non-lubricated environments.

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.

Created for highly specialized applications—against soft metals in “non-lube” conditions. Its excellent coefficient of friction and good creep resistance mean that not only will your SP-221 part have excellent wear, but so will the soft metal parts that
come in contact with it.

Need a bearing material that offers all the benefits of SP-22, plus the advantage of stable frictional properties and longer life? SP-224 is your answer. This patented material goes the extra mile—providing additional load-carrying capability.

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.

High modulus, low elongation, high compressive strengths and low creep—these products provide them all. Graphite-filled for low friction, SMR-0454 and SMR-0747 offer the same thermal resistance as the SP products, with less deflection under load. The addition of carbon fibers in SMR-0454 gives extra benefits: a steel-like coefficient of thermal expansion and better thermal conductivity.

Want a material that wears like SP-21, but with improved toughness and better thermal oxidative stability? Consider ST-2010 or ST-2030. These products even include better resistance to solvents, acids and bases.

»

Materials designed for those demanding applications that require even more toughness, thermal stability and chemical resistance than ST-2010. SCP-50094 has been put to the test in ultra-high-stress environments like aircraft engines. So, it’s ready for just about any design challenge. But for better plasma resistance, dimensional stability and chemical resistance than
SP-1, check out SCP-5000.

As any engineer knows, sometimes strength lies in flexibility. Allow us to introduce SM-30084. It was originally developed to provide higher elongation for engine piston rings and valve spring washers. But, because of its outstanding strength,

S Line’s “best in class” regarding thermal oxidation resistance and thermal stability. (It’s even better than SCP-50094!) As such, SMP-40025 is ideal for use in jet engines—particularly high-vibration applications. Its high modulus and low elongation provide dimensional stability at temperatures and loads that make other polymers wilt.

Other materials “can’t touch” SF-0920’s superior thermal and electrical insulating properties, not to mention resilient cushioning. That’s what sets SF-0920 apart from the rest of the Vespel® Parts and Shapes S line. This unique polyimide foam has high durability and thermal resistance that make it ideal for use in those “can’t-touch” hot-material-handling applications. Plus, it’s lightweight and safe—won’t burn, offgas, or release toxic fumes
