Delrin is a type of acetal homopolymer and therefore generally interchangeable with others of the same class. This means that Delrin still offers the same core benefits of general acetal plastics, such as: Excellent dimensional stability. Friction, fatigue, and abrasion resistance.

What is the difference between acetal and Delrin?
Delrin® is an acetal homopolymer and has a uniform backbone with a larger crystalline block structure than acetal copolymers providing better chemical bonding. As a result, Delrin® is the stiffest and strongest unreinforced technical engineering polymer available.
Is Delrin acetal resin?
The High-Performance Acetal Resin Delrin® acetal homopolymer (Polyoxymethylene POM) is the ideal material in parts designed to replace metal. Delrin® also mates well with metals and other polymers and offers excellent dimensional stability in high precision molding.
What type of plastic is acetal?
Acetal plastic, also called polyacetal and polyoxymethylene (POM), is a general purpose, semi-crystalline, engineered thermoplastic. Acetal is commonly used for parts that need to be very stiff, have low surface friction and good dimensional stability.
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.
What is equivalent to Delrin?
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. The copolymer grade offers excellent performance at a slightly lower cost than Delrin®.
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.
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.
Is Delrin and nylon the same?
Two of the most commonly used engineering plastics are acetal (known by many names like Delrin and POM) and nylon, which both offer low coefficients of friction and excellent durability. These two materials can also be used for many of the same applications, such as bearings, bushing, and high-performance gears.
Can Delrin be cast?
Therefore, DELRIN® acetal resins frequently can replace die-cast alloys, brass and sheet metal on both cost and performance basis.
What kind of plastic 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.
Is Delrin flexible?
Delrin® provides dimensional stability in high precision molding and flexibility of design.
What is stronger than Delrin?
Chemical Resistance 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 Delrin be 3D printed?
Delrin is a 3D printing material with excellent resistance to wear, is an ideal material for such parts and functional prototypes. Another property that a 3D printing material should have for making parts and functional prototypes like gears and bearings is the material’s coefficient of friction.
What Delrin 570?
DELRIN® 570 is a 20% glass filled homopolymer acetal with enhanced dimensional stability, high stiffness, and low creep for superior part performance and higher mechanical properties at elevated temperatures when compared to unfilled DELRIN®.
How long does 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.
