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. Delrin is the trade name for the polymer material polyoxymethylene or POM.
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 nylon better than Delrin?
Nylon is the best material to work with if you are looking to use 3D printing capabilities, and it also can be used in higher temperature situations than Delrin.
What is nylon plastic called?
The name “nylons” refers to the group of plastics known as ‘polyamides’. Nylons are typified by amide groups (CONH) and encompass a range of material types (e.g. Nylon 6,6; Nylon 6,12; Nylon 4,6; Nylon 6; Nylon 12 etc.), providing an extremely broad range of available properties.
What plastic is stronger than nylon?
Both nylon and polypropylene are durable and resistant to stress, but polypropylene is stronger than nylon. In fact, polypropylene is sometimes referred to as the “steel of plastics” due to its high strength.
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.
Is Delrin a plastic?
Polyoxymethylene (POM), more commonly known as acetal or its branded name Delrin®, is an engineering plastic offering low friction, high stiffness, and excellent dimensional stability. Polyoxymethylene is a category of thermoplastics and includes many different formulations of the material, all of which vary slightly.
Is plastic and nylon the same?
All nylon is plastic, not all plastic is nylon. Nylon is polysemic; (a) it is the name for one of a set of related polymers; (b) it is the name for the woven material often made from these.
What is the most wear resistant plastic?
The most important polymers for friction and wear include polycarbonate and polyetherimide. Polycarbonate (PC) has good impact strength, high heat resistance, and good dimensional stability. PC also has good electrical properties and is stable in water and mineral or organic acids.
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.
Why is nylon called nylon?
It worked! Carothers drew out fibers that were long, strong, and very elastic. Du Pont named this product nylon. The chemists called it Nylon 66 because the adipic acid and hexamethylene diamine each contain 6 carbon atoms per molecule.
Is nylon and polyamide the same?
These fabrics are also made from polyamide chains, but they are not synthetic in any way. Nylon: In most circles, “nylon” and “polyamide fabric” are synonymous, and this polymer is the type of polyamide fabric that is most commonly used in consumer applications.
Why is nylon called a polyamide?
Nylons are also called polyamides, because of the characteristic amide groups in the backbone chain. Proteins, such as the silk nylon was made to replace, are also polyamides. These amide groups are very polar, and can hydrogen bond with each other.
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.
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 Delrin a Teflon?
Delrin is a thermoplastic material, unlike Teflon. Teflon is made of polytetrafluoroethylene. Whereas, Delrin is composed of polyoxymethylene. Teflon has dielectric properties and is used in electric circuits.
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.
What kind of plastic is Delrin?
acetal resins
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.
What is better than Delrin?
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.
Who manufactures Delrin?
DuPont
Authentic Delrin® acetal homopolymer is available exclusively from DuPont, authorized DuPont distributors, and from stock shape suppliers in a variety of forms (sheets, rods, tubes).
How hard is Delrin?
It’s true that Delrin is an easy material to work with in terms of machining. It is a very stable material, which makes precise, tight tolerances easier to achieve for this thermoplastic. While machining, keep in mind that Delrin is sensitive to heat at or above 250 °F (121°C).
