DELRIN® 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 pH 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 may be requested from resin that is FDA, NSF and USDA compliant. Standard stamped parts are NOT FDA without request
- 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.
