Evonik, a specialty chemicals company, has developed a new polymer powder for applications in higher temperature range as part of its polyamide 6 series.
The new polyamide powder offers high mechanical strength as well as chemical and temperature resistance. Its heat deflection temperature (HDT B) is around 195°C. Plus, the powder material has low water absorption – below 3% —, which has a positive effect on processability in 3D printing and the dimensional stability of printed 3D components.
The polymer powder in Evonik’s polyamide 6 series has a nearly round grain shape for excellent flowability and application properties, making it suitable for all powder-based 3D printing technologies. A proprietary procedure of Evonik is used to produce the high-temperature material at the company’s Marl site.
