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 another name for Delrin?
Acetal
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 harder than acetal?
The hardness difference between Acetal copolymers (POM-C) and homopolymers (POM-H) is fairly marginal(85 Shore D versus 86 Shore D). However, the Delrin® homopolymer does tend to have a slightly higher hardness than Acetal copolymer.
Is Delrin acetal resin?
The High-Performance Acetal Resin
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 type 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 and nylon the same?
Nylon is a type of polyamide that is synthetic. 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.
Is Delrin flexible?
Despite the fact that it has many of the properties of Delrin, it’s not as strong and it’s more flexible. This makes it less appropriate for several of the industrial applications that Delrin is used for.
Is Delrin self lubricating?
Well-Known Member. delrin is self lubricating but if you want to grease it go ahead. delrin is one of the most chemically resistant plastics there is. no grease will hurt it.
Is Delrin brittle?
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.
Is Acetron a Delrin?
Acetron® AF Blend is a unique thermoplastic material for use in moving parts in which low friction and long wear life are important. It is a combination of PTFE fibers uniformly dispersed in Delrin acetal resin.
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.
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.
Are there different types of Delrin?
The very low emission toughened grades (Delrin® 100STE, 100TE, 100MTE, 300TE, and 500TE) offer a finer-tuned viscosity range over the standard toughened grades (Delrin® 100ST, 100T, and 500T), with the availability of the Delrin® 300TE.
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.
What material is Delrin?
Polyoxymethylene
Delrin, also known as Polyoxymethylene (POM), is a high-performance acetal resin with several desirable physical and mechanical properties. This highly-crystalline engineered thermoplastic is widely regarded for its durability, stiffness, and exceptional dimensional stability.
What is Delrin good 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.
Is Delrin a PTFE?
Delrin AF is a combination of 10-25% oriented PTFE fluorocarbon fibers uniformly dispersed in Acetal/Delrin resin. The resulting product is one that possesses the strength, toughness, and dimensional stability of Acetal with the added properties of PTFE, which is one of the world’s most slippery solid materials.
Which is harder Delrin or UHMW?
Delrin is stiffer and stronger in unfilled form, has shorter molding cycles, easy to machine, low moisture absorption, and better surface finish.
Is HDPE the same as Delrin?
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.
Can you glue Delrin?
Delrin in particular cannot be glued to itself with any sort of significant bond strength with a one-part. By saying Delrin I am referring to both acetal homopolymer and acetal copolymer. The reason for thisis that one-part solvent based adhesives do not dissolve the surface of Delrin plastic shapes properly.
Can Delrin be 3D printed?
Most Delrin 3D printing applications are high-performance engineering parts like gears and bearings. Apart from having to deal with load and pressure, parts like gears are also subject to wear. As Delrin has a high resistance to wear, it’s an ideal material choice for such parts.
