What is a Delrin washer?

What is a Delrin washer?

Delrin® is a unique formulation of Polyoxymethylene (POM) developed by DuPont™. This thermoplastic is a high-performance acetal homopolymer resin with numerous desirable physical, mechanical, and chemical properties. It is especially renowned for its durability, stiffness, and dimensional stability.

Is Delrin wear resistant?

Delrin® acetal homopolymer (Polyoxymethylene POM) is the ideal material in parts designed to replace metal. It combines low-friction and high-wear resistance with the high strength and stiffness such applications require.

What is Delrin plastic used for?

Delrin is Ideal for Industrial Applications Parts exposed to a moist or wet environment, such as pump and valve components, are especially appropriate. Other common uses include gears, bearings, bushings, rollers, fittings, and electrical insulator parts.

Does Delrin break easily?

Machining Delrin With PTFE, we need to consider the softness of the material and also its sensitivity to temperatures, with nylons and UHMWPE, we need to be careful of the part melting during machining, with PEEK, the tool itself can break, if we do not control the RPM.

What is a Teflon washer?

Teflon or PTFE washers are flat discs with a centrally located hole. They have superior antifriction properties, as well as excellent chemical and corrosion resistance. These washers are ideal for low-temperature applications. Flat washers are thin and flat, and have a centrally located hole.

How long does Delrin last?

Mechanical Properties Delrin has outstanding fatigue resistance, almost indefinitely withstanding cyclic compressive/tensile stressing 5,000 psi. Delrin does not permanently deform or retain dents, and has good impact toughness.

Is POM same as Delrin?

Acetal is the common name for a family of thermoplastics with the chemical name “PolyOxyMethylene”, or POM. Acetal is available in two general types of resins: Copolymer acetal (POM-C), and homopolymer acetal (POM-H); commonly called Delrin®. Each type of acetal has its own set of advantages and disadvantages.

Is nylon harder than Delrin?

They are also nowhere near as strong as Delrin. It is possible to get glass filled nylon but cutting threads in that is a lost cause I think. Delrin is probably the strongest non reinforced plastic available (at an acceptable cost).
