What Delrin 100?

What Delrin 100?

Delrin 100 is a high viscosity acetal homopolymer for use in easy to fill molds. Delrin 100 provides maximum toughness in the product line without modification and optimum mechanical performance. Information provided by DuPont Performance Polymers. Key Words: POM.

What are the properties of Delrin?

Delrin® is a crystalline plastic that offers an excellent balance of properties that bridge the gap between metals and plastics. Delrin® possesses high tensile strength, creep resistance and toughness. It also exhibits low moisture absorption. It is chemically resistant to hydrocarbons, solvents and neutral chemicals.

Is POM and Delrin the same?

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®.

Are there different grades 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 temperature can Delrin withstand?

Thermal Properties Delrin does not use plasticizing for toughness: and so does not become brittle at low temperatures. Impact resistance at -40° F is only 20% less than that at room temperature. Delrin’s upper service temperatures are: 180° F in air, 150° F in water, with brief peaks to 250° F.

What is the yield strength of Delrin?

8,000
Delrin AF Blend

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 wear resistant?

· Delrin Copolymer Delrin copolymer is made from resins specifically designed for wear resistance. As a result, it possesses exceptional mechanical properties, including stiffness, low water absorption, and dimensional stability. It is also resistant to organic solvents such as ketones and esters.

Is POM toxic?

Results: POM brackets produce toxic formaldehyde gas whether heated or mechanically abraded. Both POM products started to degrade at approximately 250 degrees C, and, by 420 degrees C, both products had completely decomposed into their fundamental molecular structure, formaldehyde.

Can POM plastic be glued?

POM is extremely solid, hard and stiff in a wide temperature range. POM has a low surface energy of ~36mN/m and therefore is typically very difficult to bond. Surface treatment will improve adhesion and bonding results significantly.

What is POM polymer?

POM – also known as acetal or polyacetal – is a highly crystalline, high-performance engineering polymer that displays a broad range of properties, particularly its low coefficient of friction, excellent wear resistance, high modulus and resistance to many solvents and automotive fuels.

Can you glue Delrin?

Delrin in particular cannot be glued to itself with any sort of significant bond strength with a one-part. The reason for thisis that one-part solvent based adhesives do not dissolve the surface of Delrin plastic shapes properly. Solvent based adhesives work by making the two surfaces a material to be bonded “sticky”.

What are the properties of Dupont Delrin 100?

1 Toughness, high impact strength, high resistance to repeated impact, and high elongation without the need for impact modifiers. 2 High mechanical strength and rigidity, without the need for fillers/reinforcements or other modifications. 3 Outstanding creep resistance and long-term fatigue endurance.

What makes a delrin 100 acetal homopolymer special?

The resins in the Delrin® 100 acetal homopolymer series are distinguished by their high molecular weight relative to other acetal grades. This identifying feature of these high performance acetal homopolymers, along with their natural high crystallinity, yields materials that have:

Which is better Delrin 100 or 100p copolymer?

Delrin® 100 and 100P have very high Tensile Strength and Strain at Break, significantly higher than the standard copolymer. These relative advantages are maintained at elevated temperatures as well. Delrin® acetal homopolymers are readily processed with a variety of molding machines and tooling configurations.

What are the physical properties of Delrin acetal?

Common features of Delrin® acetal resins include mechanical and physical properties such as high mechanical strength and rigidity, excellent fatigue and impact resistance, as well as resistance to moisture, gasoline, lubricants, solvents, and many other neutral chemicals.
