PEEK powder is produced by grinding the coarse powder obtained after PEEK polymerization. Powders with different particle sizes can be produced using different grinding processes. PEEK5600P Fine Powder is a medium melt flow rate grade suitable for processing methods such as compression molding and spray coating.
