Delrin® Sheets, Rods, & Tubes

Delrin, also known as Polyoxymethylene (POM), is a high-performance acetal resin with several desirable physical and mechanical properties. This highly-crystalline engineered thermoplastic is widely regarded for its durability, stiffness, and exceptional dimensional stability.

These characteristics make Delrin ideal for high-load and high-impact applications such as gears, conveyor belts, bearings, rollers, and safety restraints. Additional low moisture absorption and tribological properties lend themselves to the construction of items in wet or moist environments such as pumps, valves, and actuators. 

Delrin sheets, tubes, and rods can be cut and machined to required lengths and shapes to create a variety of parts and components. 

What Are The Benefits of Using Delrin?

Delrin offers a balance of the exceptional properties found in metals and plastics. Specifically, the material offers:

• High strength and stiffness properties – Delrin boasts an impressive compressive strength of 5200 psi (by comparison, concrete has a compressive strength between 2500 psi and 4000 psi). This property, combined with its high stiffness, makes Delrin ideal for high-impact and heavy load carrying applications.
• Superior dimensional stability – Capable of maintaining its original shape and dimensions when subjected to changes in temperature and humidity, Delrin is especially useful in applications that are sensitive to dimensional changes, such as gears and bearings.
• Low moisture absorption – Delrin’s resistance to moisture allows the material to maintain its physical and mechanical properties even when operating in environments with high levels of moisture and humidity. Pumps, valves, and plumbing fixtures are just some examples of components that can benefit from Delrin construction.
• Excellent impact and creep resistance – Heavily loaded applications require materials that are exceptionally durable under extreme stress. Delrin’s impact and creep resistance contribute to its ability to resist denting and time-dependent deformation under heavy loads.
• Chemical resistance to fuels and solvents – Delrin’s resistance to fuels and solvents allow it to operate in petroleum-based applications without property degradation or deterioration, making it particularly suitable for piping, tank, and vessel fittings in the petrochemical industry.
• Excellent machinability – Despite its high strength and stiffness, Delrin can be easily cut into any desired shape using a variety of tools.
• Exceptional wear and abrasion properties – The material is also widely regarded for its resistance to wear and abrasion, which is especially crucial in gears where components are frequently in contact with one other. Delrin fittings can also be used in piping systems used to convey abrasive material. This material also possesses a relatively low coefficient of friction, thus minimizing friction between moving parts.
