DELRIN® 570 - 20% glass fiber filled

DELRIN®570 Shapes manufactured by Ensinger are 20% glass filled materials intended for general industrial use. The material offers very high stiffness, low warpage, and low creep for superior part performance under stress.

  • Very good dimensional stability
  • Glass fibers offer stiffness but not reinforcement
  • Good machinability

DELRIN® 570 is used in a variety of industries such as automotive or construction where added strength and stiffness are desirable.
