Printing behaviour
A high-performance material, PEKK-SC is processed with a recommended extrusion temperature of 350 to 400 °C and a heated bed of 110 to 170 °C, at a speed of 20 to 40 mm/s. A high-temperature FDM printer with an enclosed, heated chamber is essential.
Its semi-crystalline structure gives it thermal resistance higher than that of amorphous PEKKs, but requires precise management of crystallisation during printing. Pre-drying is recommended, with the residual moisture content needing to remain below 1 %.
Properties and applications
PEKK-SC combines a glass transition temperature of 161 °C, a melting temperature of 332 °C and thermal resistance up to 260 °C with good resistance to abrasion and chemicals. Its compliance with the EN45545 railway and FAR 25.853 aerospace fire-smoke standards makes it suitable for components exposed to acids and hydrocarbons, such as fuels and lubricants, in the railway, aerospace and industrial sectors.
Store away from light, moisture and heat in order to preserve the product's properties.
