Vespel® S Family

Vespel® S Polyimide Family

Vespel® S polyimide family of parts and shapes with differing sets of attributes

The Vespel® S Family of products are highly durable polyimides and are used in demanding applications where exceptional thermal resistance, low wear and/or low friction, strength and impact resistance are desired.

SP-1                                                                              

Unfilled. Superior wear and insulation properties with operating temperatures from cryogenic to 300°C. Low electrical conductivity. Highest elongation and purity of SP family. Available as custom parts or stock shapes.

SP-21                                                                                

Graphite-enhanced with low-friction properties for use with or without lubrication in various applications.  Available as custom parts or stock shapes.

SP-202

Conductive parts (<10E2 ohm) to help the elimination of static charge.  Excellent wear resistance, dimensional stability at high temperatures and good machinability. Available as stock shapes.

SP-211                                                                               

Lower coefficient of friction than SP-21 without lubrication in various applications. Available as custom parts or stock shapes.

SP-22                                                                              

Minimal thermal expansion and dimensional stability for design flexibility.  Available as custom parts or stock shapes.

SP-221                                                                              

For highly specialized applications—against soft metals in “non-lube”  conditions. Available as custom parts.                                                                                     

SP-2515                                                  

Low coefficient of thermal expansion, excellent wear properties and a low coefficient of friction for dimensional control.  Available as custom parts.

SP-3                                                                              

Used in vacuum and dry environments with low outgassing.   Available as stock shapes.                                                  

SMR-0454

Graphite-enhanced for low friction. High modulus, low elongation, high compressive strength and low creep with less deflection under load.  Available as custom parts.

ST-2010

Similar to SP-21 with improved toughness, higher elongation and better thermal oxidative stability. Better resistance to solvents, acids and bases.  Available as custom parts.

ST-2030   

Similar to SP-22. Found in applications in which low thermal expansion is more important than strength (which is slightly reduced). Applications may include bearings, bushings and washers. Available as custom parts.

SCP-5000

Unfilled SCP-5000 has better plasma resistance, dimensional stability and chemical resistance than unfilled SP-1. Like SP-1, SCP-5000 has good insulation.  It has the highest elongation and purity of the SCP grades.  Available as stock shapes.

SCP-5050, SCP-5009 & SCP-50094                                                                              

Higher thermal oxidative resistance than SP polyimides with superior chemical resistance. SCP-5050 matches the CTE of steel. SCP-5009 and SCP-50094 approximates the CTE of aluminum.  Available as custom parts or stock shapes.

SMP-40025

High modulus and low elongation provide dimensional stability at high temperatures and loads.  Available as custom parts.

SF-0920, SF-0930, SF-0940

Superior thermal and electrical insulating properties. Unique polyimide foam has higher durability compared to low density polyimide foams.  Available as custom parts.
