Comparison. Accessed 28 Aug. 2017.
Both POM-C and PA 6 are thermoplastics.
Sliding wear against mating metal parts. A vague tip , but here goes : if they`re both un-reinfoced I rub it with my fingers , nylon barstock (at least the kind I use) has a higher surf.roughness then delrin , it feels more `ridged` (excuse my poor english). “Acetal.” Curbell Plastics, Available here.
When it comes to high-performance thermoplastic resins, the debate is often UHMW vs. acetal.Both offer strength and excellent performance in wear applications, but their differences come into play when considering your application.
Acetal & PET.
Lower numbered nylons, 6 ,6-6, 4-6, absorb moisture and change their properties as a result. The generic Acetal covers both the homo-polymer Delrin® and the co-polymer grades of resin.
Both POM-C and PA 6 are thermoplastics. Acetal Copolymer (POM-C) Polyamide (PA, Nylon) 6. Image Courtesy: 1. Both materials meet the ASTM-D-4181, ASTM-D-6100 or ASTM-D-6778 specification (an old call out is L-P-392).
After several weeks of testing, I am happy to say that we are 3D printing in acetal. Acetal gives you a really nice surface finish when machined and lubricates itself better. There are 6 material properties with values for both materials. Acetron ® GP is a copolymer acetal. 4 at a running speed of 1 000 rpm over Accessed 28 Aug. 2017. Acetal Products Comparison: Acetal vs. Delrin . Acetal is also recognised for its flexural memory when put under pressure over a long period of time. However, it has more than double the tensile, flexural and compressive strength of polypropylene, making it better for fittings in particularly high-stress environments. Delrin® is a part of the Acetal family of thermoplastics, but has a few distinguishing characteristics. Delrin has a more `greasy` feel to it then nylon , altough not as greasy as teflon.
Delrin® is a part of the Acetal family of thermoplastics, but has a few distinguishing characteristics.
>Polyoxymethylene (POM) Plastic Up Two > POM-C Up One POM-C Up One. There are 6 material properties with values for both materials. “Why Choose Acetal Or Delrin.” Directplastics , Available here. Fatigue in mechanical parts in non-ambient temperatures are a bit more likely to occur in nylon.
Lots of players like nylon picks specifically for the reason that they can be made very, very thin. Acetal vs Delrin® Delrin® is a homo-polymer Acetal produced by Dupont.
MATERIAL SELECTION … It is well known for its excellent tensile strength and chemical resistance. Plastics such as UHMW, nylon, and acetal are excellent choices for wear applications that involve sliding against mating metal parts. Acetal vs Delrin® Delrin® is a homo-polymer Acetal produced by Dupont. Redco™ Acetal & Redco™ PET brings together the benefits of strength, stiffness, low coefficient of friction, and dimensional stability providing a versatile and easily machinable material that exceeds the life of many parts that are traditionally metal.. Redco™ PET is a popular within the food and beverage industry. Choosing the right material for your product can mean the difference between a good product and a great one. 2. Recent Posts. Homo-polymer is POM111, and Co-polymer is POM211. Properties with values for just one material (13, in this case) are not shown. It has desirable toughness properties, performing well at extreme temperatures and under fatigue endurance.
Two closely-related materials that get compared a lot are Acetal copolymers and Delrin® homopolymers.
Acetal .
For each property being compared, the top bar is POM-C and the bottom bar is PA 6. (As a quick overview, Acetal (or Delrin, or POM) is a strong, rigid thermoplastic with excellent wear resistance and very low friction. In most applications, acetal is used for molded gearing and nylon is used for machined gearing.
Choosing the right material for your product can mean the difference between a good product and a great one.
POM has high flexural and tensile strength, stiffness and hardness. … Acetal & PET. One of the biggest differences between Acetal and Delrin® is centreline porosity, which is a characteristic of Delrin® but not Acetal. Redco™ Acetal & Redco™ PET brings together the benefits of strength, stiffness, low coefficient of friction, and dimensional stability providing a versatile and easily machinable material that exceeds the life of many parts that are traditionally metal.. Redco™ PET is a popular within the food and beverage industry. Nylon against nylon and acetal against nylon gear tests Tests wer e carried out using a nylon material (ny lon against nylon gears), as shown in Fig. Nylon is ideal as a filament for 3D plastic printing, but it absorbs water over time.
