The proprietary TruTech® line of materials from Cook Compression includes custom PTFE, modified PTFE, UHMWPE, PEEK, PPS, polyimide and other high-temperature aromatic polymer materials.
Our engineers and materials scientists work together to recommend material formulations based on your application-specific requirements.
Special formulations provide high-performance sealing and lasting reliability for even the most demanding non-lubricated, dry-gas and high-temperature applications.
In-house precision blending capabilities enable Cook Compression to enhance specific material properties. Materials incorporate reinforcements, fillers and additives such as:
With its extremely low coefficient of friction, PTFE materials are the most common type of material used in reciprocating compressor piston, rider and packing rings.
Generally stronger than PTFE materials, PEEK materials are the second most common type of material for piston, rider and packing rings. They may also be specified for valve components in high-temperature environments.
Specialty PPS materials have broad chemical resistance. Polyimides are suitable for extreme, high-temperature applications and are resistant to most chemicals.
