PEKK for High Temperature Applications

Goodfellow offers polyetherketoneketone (PEKK) granules that provide significant advantages when used to produce injection-moulded components for high-temperature engineering applications.

PEKK has a glass transition temperature (Tg) of 162°C (semi-crystalline grade) and is able to maintain a high degree of chemical resistance as well as its physical properties up to its Tg. In addition, PEKK has an extremely slow rate of crystallisation, leading to improved flow characteristics, lower moulded-in stresses and greater dimensional stability. This slow rate of crystallisation also makes it possible for amorphous films of PEKK to remain transparent even at higher operating temperatures, when materials like polyetheretherketone (PEEK) will have crystallised and become opaque.

PEKK is also available from Goodfellow as film, sheet and rod – forms that are used in applications that include flexible PCBs and items used in aerospace and radiation environments .

Goodfellow is a leading supplier of metals, polymers, ceramics and other materials to meet the research, development, and specialised production requirements of science and industry worldwide. The Company specialises in supplying small to medium size quantities (a few grams to a few kilos) of metals and materials for research, prototype development and specialised manufacturing applications. The comprehensive Goodfellow Catalogue can be accessed in English, French, German, and Spanish at
