DELRIN® 570 natural
DELRIN® 570 Shapes extruded by Ensinger are 20% glass filled materials intended for general industrial use. The POM GF material from Delrin USA LLC offers very high stiffness, low warpage, and low creep for superior part performance under stress. The user can also count on good dimensional stability and machinability, however should also note that the fibers offer stiffness but not reinforcement. Delrin® is a registered trademark of Delrin USA LLC.
