Material Notes:

Product Description: Grilamid L 20 LF grey is a medium viscosity graphite filled Polyamide 12 (PA12) grade suitable for both injection molding and extrusion applications. Grilamid L 20 LF grey has been modified with graphite to provide a low coefficient of friction, is heat stabilized, easy to mould and eject from the mould tool. The special features of this product are: Low coefficient of friction Dimensional stability Low moisture absorption Easy to process Low weight and low density The inherent color of this material is grey.Application examples: This product has been developed to provide a low coefficient of friction and can be used in applications for bearings, guide sleeves and bowden cables.Information provided by EMS Grivory
