DELRIN® 511P enhanced homopolymer

DELRIN 511P is another Homopolymer acetal from DuPont that offers enhanced crystallization characteristics. This higher level of crystallization helps to augment aspects of the physical properties such as fatigue strength, stiffness, and creep resistance.

  • Good machinability
  • High stiffness
  • High fatigue strength
  • High creep resistance
  • Good wear properties
  • Very good abrasion resistance
