What Is Delrin

What Is Delrin

Delrin is a trademarked name for acetal resins that are semi-crystalline thermoplastic polymers. This type of material is also known by the abbreviation POM or polyoxymethylene. It has gained popularity since first being introduced to the commercial marketplace in 1960.

What is Delrin plastic used for?

Delrin Plastic 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.

What is another name for 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®.

What material is Delrin?

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.

Does Delrin break easily?

As a machined item, Delrin is particularly easy to work with. 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.

Is Delrin and nylon the same?

The key difference between Delrin and nylon is that Delrin is a thermoplastic made from polyoxymethylene, whereas nylon is a thermoplastic made from the reaction between an amide and dicarboxylic acid. Delrin is the trade name for the polymer material polyoxymethylene or POM.

What is stronger than Delrin?

Acetal has a better resistance to the effects of hot water and strong caustic solutions with a high pH value when compared to Delrin®. This makes Acetal a better choice for parts and materials handling applications involving the use of strong base chemicals.

Can you bend Delrin?

Yes, Delrin can be heated and bent but you should be careful not to heat it too close to its melting point where it will turn into a liquid.

Is Delrin a hard or soft plastic?

Properties & Grades of Machined Delrin

This strong, stiff and hard acetal homopolymer is easy to machine and exhibits dimensional stability and good creep resistance, among several other desirable qualities.

Can I melt Delrin?

The recommended melt temperature for Delrin® is 215+/-5ºC highlighted area) at which the melt for standard grades will remain perfectly stable for over 30 minutes.

Can you laser cut Delrin?

A 1.06 micron wavelength Fiber laser can be used to laser mark Delrin® in certain cases. The carbon based pigment in black Delrin® is heated by the laser beam, causing the surrounding polymer to foam. The foam scatters light creating an off-white, indelible mark in the Delrin® surface.

Is Delrin the same as HDPE?

While HDPE Sheet and Acetal Sheet look similar, they perform quite a bit differently. Acetal is commonly known as: Delrin Homopolymer Acetal, Tecaform AH,Ensital, Unital, Pomalux, Ultraform and many more. HDPE is also known as: Ultraethylux, Densetec, Polystone G, Fortiflex, Versadur, Hostalen, and many more.

Is Delrin a strong material?

Delrin® plastic properties and mechanical specifications

Delrin® plastic is strong, rigid, and resistant to impact, creep, abrasion, friction, and fatigue.

Is Delrin heavier than aluminum?

Delrin is still somewhat strong and is lighter than aluminum.

Is Delrin scratch resistant?

Delrin® The stiffest and highest design strength non reinforced plastic. It has a hard, scratch resistant surface, low friction, excellent resistance to hydrocarbons and high fatigue endurance.

How long will Delrin last?

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.

Can Delrin be threaded?

Delrin® homopolymer is used to make screws, hex nuts, threaded rod, set screws, as well as many other fasteners and custom parts.

Can you sand Delrin?

sand it from 180 grit through to 600 preferably with steam ate lubricated paper or ABRANET at slow speed in the lathe . Then wet sand with wet n dry upto about 1200 grit, follow with metal polish eg t cut if you want a really gloss finish. doesnt take long with each grit but wipe the work between grits with.
