PEEK-Based TruTech Materials
Proprietary PEEK Formulations
PEEK (polyetheretherketone) materials are the second most common type of material for reciprocating compressor piston, rider and packing rings (after PTFE). They may also be specified for valve components in high-temperature environments.
The TruTech® materials line features a number of proprietary PEEK compounds to meet specific operating conditions.
PEEK Material Properties
PEEK, like PTFE, has broad resistance to most common chemicals in the oil & gas industry and is capable of running continuously at temperatures up to 250°C (490°F). PEEK materials are generally stronger than PTFE materials.
While fillers are not always required with PEEK, they may be incorporated to enhance material performance for specific operating conditions. PTFE and other self-lubricants, such as graphite and MoS2, are typically used to reduce the relatively higher coefficient of friction of PEEK.
Reinforcing and wear resistant fillers may also be introduced to further improve mechanical and wear properties.
Material Grades Tailored to Operating Requirements
Depending on compressor lubrication, gas composition, temperature and other operating conditions, Cook Compression may propose PEEK materials of standard, upgrade or specialty grade. For specific material properties, please reference the TruTech materials catalog.
Standard PEEK Materials
Standard grade PEEK materials are suitable for most lubricated compressor service and include:
• K1000
• K1030
• K1050
Upgrade PEEK Materials
Upgraded PEEK materials provide more lubricity and higher strength than our standard grade. These materials include:
• K2310
• K2330
• K2340
Specialty PEEK Materials
Our specialty grade PEEK materials use premium fillers and proprietary formulations to meet the requirements of difficult applications, including non-lubricated dry gas service. TruTech specialty PEEK materials include:
- K3400
- K3410
- K3420
- K3430
- K3510
- K3520
More from Our TruTech Line
PTFE Materials
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.
PPS and Polyimide Materials
Specialty PPS materials have broad chemical resistance. Polyimides are suitable for extreme, high-temperature applications and are resistant to most chemicals.
Complete In-house Processing Capabilities
Material compounding, compression molding and machining are all performed in-house and are closely monitored to ensure the quality and consistency of finished products.
