\r\n Engineering Logic Behind Selecting PPS, PSU, POK, PEEK and TPEE\r\n <\/h2>\r\n\r\n

\r\n These polymers cover different engineering scenarios. They cannot be evaluated as a single group of \u201cstrong plastics\u201d, since each material has its own zone of technical relevance, limitations and advantages in the real part.\r\n <\/p>\r\n

\r\n\r\n

\r\n Separately on polyketone POK \/ PK:<\/strong> 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.\r\n <\/p>\r\n\r\n \r\n Go to the polyketone POK technical page \u2192\r\n <\/a>\r\n\r\n <\/div>\r\n

\r\n PPS \u2014 heat resistance, chemical inertness and stable geometry\r\n <\/h3>\r\n\r\n

\r\n PPS is used where high heat resistance, low creep, chemical inertness and dimensional stability in serial injection molding are required.\r\n <\/p>\r\n\r\n

\r\n 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.\r\n <\/p>\r\n\r\n

\r\n PSU \u2014 heat-resistant structural parts with improved impact toughness\r\n <\/h3>\r\n\r\n

\r\n 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.\r\n <\/p>\r\n\r\n

\r\n 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.\r\n <\/p>\r\n\r\n

\r\n POK \u2014 wear resistance, low friction and performance under cyclic loading\r\n <\/h3>\r\n\r\n

\r\n POK is of interest in applications where wear resistance, low friction, chemical resistance and performance under cyclic loading are critical.\r\n <\/p>\r\n\r\n

\r\n 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.\r\n <\/p>\r\n

\r\n\r\n

\r\n In-depth technical review of POK\r\n <\/h3>\r\n\r\n

\r\n 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.\r\n <\/p>\r\n\r\n \r\n Open the Polyketone POK \/ PK page \u2192\r\n <\/a>\r\n\r\n <\/div>\r\n

\r\n PEEK \u2014 maximum thermomechanical endurance\r\n <\/h3>\r\n\r\n

\r\n 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.\r\n <\/p>\r\n\r\n

\r\n 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.\r\n <\/p>\r\n\r\n

\r\n TPEE \u2014 elasticity, fatigue strength and stability under dynamic loads\r\n <\/h3>\r\n\r\n

\r\n 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.\r\n <\/p>\r\n\r\n

\r\n It is used where a combination of elasticity, thermoplastic processability and higher mechanical endurance is required compared with many standard elastomer solutions.\r\n <\/p>\r\n\r\n

\r\n Critical parameters for selecting a high-performance polymer\r\n <\/h2>\r\n\r\n

\r\n 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:\r\n <\/p>\r\n\r\n

    \r\n
  • HDT, Tg or Tm;<\/li>\r\n
  • modulus at operating temperature;<\/li>\r\n
  • creep resistance;<\/li>\r\n
  • moisture absorption;<\/li>\r\n
  • behavior after heat aging;<\/li>\r\n
  • chemical compatibility;<\/li>\r\n
  • coefficient of friction;<\/li>\r\n
  • wear when paired with metal or plastic;<\/li>\r\n
  • electrical insulation properties;<\/li>\r\n
  • self-extinguishing behavior;<\/li>\r\n
  • shrinkage stability;<\/li>\r\n
  • the ability to achieve repeatable geometry in serial production.<\/li>\r\n <\/ul>\r\n\r\n

    \r\n 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.\r\n <\/p>\r\n\r\n

    \r\n Material selection based on the actual duty of the part\r\n <\/h2>\r\n\r\n

    \r\n Material Wizard analyzes the part's operating conditions, processing methods, and requirements for service life, geometry, surface, rigidity, chemical resistance and project economics.\r\n <\/p>\r\n\r\n

    \r\n 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.\r\n
