What is Delrin made out of?

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 PTFE the same as Delrin?

PTFE has the lowest friction constant of any plastic material. It is not a thermoplastic but it can be extruded. … Acetal or polyoxymethylene (POM) is a semi-crystalline, non-amorphous type of thermoplastic. Delrin®, which is the DuPont brand name for Acetal, is a homopolymer.

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®.

Is Delrin the same as nylon?

Despite these similarities, nylon is generally stronger than Delrin. Extruded nylon has a tensile strength of 12,400 PSI and cast nylon has a tensile strength of between 10,000 and 13,500 PSI. In contrast, Delrin has a tensile strength of 10,000 PSI.

Are there different types of Delrin?

General purpose grades of Delrin® are available in several basic melt flow series: 100, 500, 900, and 1700. These differ primarily in melt viscosity with 100 being the most viscous and 1700 the most fluid. … Delrin® 100, 500 and 900 are known around the world for their outstanding mechanical properties.

Is Delrin flexible?

Delrin® provides dimensional stability in high precision molding and flexibility of design.

Article first time published on

Can Delrin be autoclaved?

Is Delrin® autoclaveable? Delrin® acetal resin survived 100 15-minute cycles of 121 degrees C (250° F) in an autoclave. However, additional cycles could result in surface chalking and hydrolysis.

Can Delrin be cast?

Therefore, DELRIN® acetal resins frequently can replace die-cast alloys, brass and sheet metal on both cost and performance basis.

Is Acetron a Delrin?

What is the difference between the Acetron® GP and DuPont Delrin®? Acetron® GP is a copolymer acetal. … DuPont Delrin® is a homopolymer acetal. It has slightly better mechanical properties then the Acetron® GP acetal but may contain a low-density center, especially in larger cross sections.

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.

Is Delrin stronger than ABS?

Delrin (DuPont’s brand of acetal) and ABS are both plastics. Delrin is referred to as an “engineering” plastic because it is stronger and more resistant to distortion under load. ABS is “commodity” plastic because it is cheaper and easier to mold, however because of it’s flexibility, is relatively hard to break.

Where is Delrin manufactured?

And often this Delrin® is made at the manufacturing site of DuPont in Dordrecht (the Netherlands).

What color is Delrin?

Delrin sheet available in 8 standard colors: blue, green, red, orange, yellow, purple, fluorescent green and fluorescent pink. Ensinger’s Delrin® colored sheets are a homopolymer Acetal manufactured using DuPont Delrin® 150 Resin.

Is Celcon the same as Delrin?

Other trade names for Acetal include: Celcon®, Delrin®, Ensital®, Pomalux®, Polyacetal®, POM (PolyOxyMethylene) Sustarin®, Tecaform®, Ultraform®, Unital®, and ZL 900.

Is Delrin flat?

Ordinary Delrin can be machined as flat as you specify. Don’t expect to measure it half an hour later and get the same numbers. If you assemble the part between two other parts, and e.g. rely on the flatness for sealing, do the assembly immediately after finishing.

What is the difference between Delrin and Delrin AF?

Delrin® AF Blend retains approximately 90% of the mechanical strength and rigidity of Delrin®, but with improved bearing and sliding properties, and almost no ‘slip-stick’ characteristics. Other formulations available are Delrin® 100AF containing 20% Teflon fibers and provides even lower frictional properties.
