好人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也可以从Goodfellow作为胶片，板和杆（包括灵活的PCB和航空航天和辐射环境中使用的物品）中使用。
