Engineering Logic Behind Selecting PPS, PSU, POK, PEEK and TPEE
These polymers cover different engineering scenarios. They cannot be evaluated as a single group of “strong plastics”, since each material has its own zone of technical relevance, limitations and advantages in the real part.
Separately on polyketone POK / PK: we have prepared a dedicated technical page on the use of POK in friction assemblies and in parts requiring chemical contact resistance, low water absorption and stable geometry.
Go to the polyketone POK technical page →PPS — heat resistance, chemical inertness and stable geometry
PPS is used where high heat resistance, low creep, chemical inertness and dimensional stability in serial injection molding are required.
It is a material for parts that must retain their shape, rigidity and functionality at elevated temperatures, in contact with aggressive media or in electrical engineering assemblies.
PSU — heat-resistant structural parts with improved impact toughness
PSU matters for parts that must maintain mechanical integrity at elevated temperatures while also requiring better impact toughness and stability than many rigid high-temperature materials.
This polymer is appropriate in designs where not only heat resistance matters, but also the part's ability to withstand mechanical loads without brittle failure.
POK — wear resistance, low friction and performance under cyclic loading
POK is of interest in applications where wear resistance, low friction, chemical resistance and performance under cyclic loading are critical.
It is considered for friction assemblies, moving elements, technical parts with extended service life, and products where standard polyamides or acetals may face limitations due to moisture absorption, wear or chemical compatibility.
In-depth technical review of POK
On a dedicated page, polyketone is examined in greater depth: tribology, water absorption, chemical resistance, clearance stability, performance under cyclic loading and a comparison with PA, POM, PBT and PPS.
Open the Polyketone POK / PK page →PEEK — maximum thermomechanical endurance
PEEK is used in cases that demand maximum thermomechanical endurance, resistance to aggressive media and the ability to operate in regimes beyond the reach of most engineering plastics.
It is a material for the most demanding service conditions, where the polymer must retain strength, stability and service life under high temperature, load and complex chemical environments.
TPEE — elasticity, fatigue strength and stability under dynamic loads
TPEE holds a distinct position as a thermoplastic elastomer for flexible, resilient and dynamically loaded parts, where fatigue strength, shape recovery and property stability under demanding service conditions are important.
It is used where a combination of elasticity, thermoplastic processability and higher mechanical endurance is required compared with many standard elastomer solutions.
Critical parameters for selecting a high-performance polymer
For these materials, the decisive factor is not individual datasheet values but the combination of parameters that determine how the material behaves in the real part:
- HDT, Tg or Tm;
- modulus at operating temperature;
- creep resistance;
- moisture absorption;
- behavior after heat aging;
- chemical compatibility;
- coefficient of friction;
- wear when paired with metal or plastic;
- electrical insulation properties;
- self-extinguishing behavior;
- shrinkage stability;
- the ability to achieve repeatable geometry in serial production.
The same part may require different solutions depending on the temperature profile, load duration, wall thickness, reinforcement type, in-mold cooling conditions and the acceptable cost of the finished product.
Material selection based on the actual duty of the part
Material Wizard analyzes the part's operating conditions, processing methods, and requirements for service life, geometry, surface, rigidity, chemical resistance and project economics.
This approach makes it possible to treat PPS, PSU, POK, PEEK and TPEE not as a formal list of high-tech materials, but as a set of engineering tools for specific production tasks.
