Vespel SP1 - First in the Dupont Vespel family of products - highly durable polyimides that deliver exceptional wear resistance, insulation, and a low coefficient of friction. Within the S Line, Vespel Parts and Shapes include many products with differing sets of attributes.

 

Superior wear properties, best electrical and thermal insulation for:

 

Insulators
Valve seats
Balls
Gaskets
Poppets
Wafer clamping
Clamping rings
In-chamber semiconductor parts

 

Benefits

 

Unfilled resin
Operating temps from cryogenic to 300°C (570°F)
Ultra high purity
Minimal electrical and thermal conductivity
Maximum strength and elongation
Low outgrassing

Excellent wear for longer life

 

 

 

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.

 

Superior wear and low-friction properties for:

 

Thrust washers
Seal rings
Valve seats
Bearings
Seals

 

Benefits

 

Low wear at high bearing PVs
Low coefficient of friction
Long-term thermal stability
High stiffness
Low elongation
Outstanding performance with or without lubrication
Good strength and impact resistance

 

 

 

 

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.

 

Lowest coefficient-of-friction parts in both dry and lubricated applications such as:

 

Sliding and linear bearings
Bushings
Thrust washers
Seal rings

 

Benefits

 

Low wear at high bearing PVs
Low coefficient of friction
Teflon filled
Superior unlubricated wear
Excellent creep resistance
Wear resistant up to 300 F
Good tensile strength, elongation and flexural modulus

 

 

 

 

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.

 

Graphite-enhanced polyimides for tight-tolerance applications:

 

Bearings
Thrust washers
Seal Rings
Ferrules
Sleeves
Strips
Vanes

 

Benefits

 

Enhanced resistance to friction and wear
Minimal thermal expansion
Maximum thermal conductivit
High temperature resistance
Improved dimensional and oxidative stability
Minimum elongation

 

 

 

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.

 

Excellent performance in vaccuum and dry environment applications including:

 

Bushings
Bearings
Piston Rings
Seals
Gears

 

Benefits

 

Maximum wear and friction resistance in vaccums and other dry environments
Ultra-low outgrassing
High performance in aerospace applications
