Delrin (POM) Injection Molding

Delrin is a high strength material with excellent wear resistance

polishing an injection mold

Injection-molded Delrin (POM) offers high-tensile strength, low-friction and high-wear resistance, creep and warp resistance, and overall durability and toughness. It's a high-performance material for parts that will be in harsh environments or experience heavy wear.

The Main Benefits of Delrin (POM):
  • Dimensional stability
  • Superior impact and creep resistance
  • High fatigue endurance
  • High strength and stiffness properties
  • Chemical resistance to fuels and solvents
  • Low moisture absorption
  • Good wear and abrasion properties
  • Natural grade is FDA, NSF, and USDA compliant
