DELRIN® Plate, Rod, Sheet, and Tube by Ensinger

DELRIN® by Ensinger is a crystalline plastic which offers an excellent balance of properties that bridge the gap between metals and plastics.

DELRIN® possesses high tensile strength, creep resistance and toughness. It also exhibits low moisture absorption.

It is chemically resistant to hydrocarbons, solvents and neutral chemicals. These properties along with its fatigue endurance make DELRIN® ideal for many industrial applications.
  • Good dimensional stability
  • Low moisture absorption
    DELRIN® can operate in wet environments with little effect on performance or dimensions.
  • Excellent machinability
  • High fatigue endurance
  • High strength and stiffness properties
  • Superior impact and creep resistance
  • Chemical resistance to fuels and solvents
  • Natural grade is made from resin that is FDA, NSF and USDA compliant
  • Good wear and abrasion properties
    With its low coefficient of friction and hard and resilient surface, DELRIN® is the material of choice in many wear applications.
Ensinger’s Delrin® 150 stock shapes are a homopolymer acetal manufactured using DuPont Delrin 150 Resin. It is a crystalline plastic which offers an excellent balance of properties to bridge the gap between metals and plastics.

It possesses high tensile and flexural properties, along with creep resistance and toughness, while exhibiting low moisture absorption, and fatigue endurance.
