Un-reinforced PEEK-HT polymer provides superior high temperature performance while retaining mechanical and physical properties to temperatures up to 54ºF, higher than standard PEEK polymer. |
 |
|
|
|
PEEK-HT™
is a novel high-performance material developed for applications that demand superior higher temperature resistance. |
|||
|
(374°C) this semi-crystalline, unreinforced polymer delivers extended high-temperature performance, while offering all the key characteristics of natural PEEK polymer, including toughness, strength and chemical resistance. PEEK-HT also delivers up to three times the wear resistance of standard PEEK polymer (450G) at high temperatures, substantially higher tensile strength and flexural modulus at 482°F (250°C). It has exceptional resistance to chemicals, solvents and fuels, inherent low flammability, low smoke emission and good electrical properties. This unique engineering material provides unlimited design freedom, consistent reproducibility and long-term product reliability in the most hostile of environments. |
