What is acetal resin used for?
Acetal Copolymer resin is used in applications requiring a combination of strength, low moisture absorption, chemical resistance and dimensional stability. It’s also used for high-performance engineering components. Acetal Copolymer is widely used in the consumer electronics industry and the automotive industry.
What is acetal resin made of?
A thermoplastic polymer produced by the polymerization of formaldehyde into very long, linear oxymethylene (-O-CH2-O-CH2-) chains. Polyacetal was first produced in 1959 by DuPont under the name Delrin®. The highly crystalline resin is glossy, dense, stiff and strong.
What 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 is acetal material?
Acetal (polyoxymethylene or POM) is a high strength, low friction engineering plastic that has excellent wear properties in both wet and dry environments. Acetal is chemically resistant to hydrocarbons, solvents, and neutral chemicals.
How much does acetal cost?
0.060″ X 24″ X 48″ Natural Acetal Sheet
| 1 – 2 | $105.29 |
|---|---|
| 3 – 4 | $97.63 |
| 5 + | $93.16 |
What is a copolymer resin?
n. A synthetic resin produced by joint polymerization of two or more different monomers or polymers.
What is black Delrin?
Delrin® 527 is the black equivalent to the 550 SA. It has the best machinability of all standard acetal grades. This grade has outstanding UV stabilization, even better than the 100 series black. DELRIN® 527 is a surface lubricated resin with UV stabilizer. It offers balanced properties and is resistant to UV light.
How do you make polyoxymethylene?
To make polyoxymethylene copolymer, formaldehyde is generally converted to trioxane. This is done by acid catalysis (either sulfuric acid or acidic ion exchange resins) and concurrent removal of the trioxane by distillation or extraction.
Is Delrin stronger than acrylic?
As far as durability, Delrin is WAY tougher than acrylic.
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.
What is Polythene made of?
Polyethylene plastic: a Carbon-Hydrogen molecule. Polyethylene is made up of ethylene molecules with 2 carbon and 4 hydrogen atoms.
What is the difference between acetal and ketal?
As nouns the difference between ketal and acetal is that ketal is (chemistry) any acetal derived from a ketone while acetal is (organic chemistry) any diether of a geminal diol, r2c(or’)2 (where r’ does not = h).
Is acetal and Delrin plastic the same?
Acetal is the common name used for polyoxymethylene. Acetal plastic is produced as either homopolymer acetal or copolymer acetal. Delrin is a homopolymer form of acetal. Therefore, Delrin is a derivative of acetal . All Delrin is acetal but not all acetal is Delrin.
Are HDPE the same materials as acetal?
No, they are two totally different materials. Although the natural color of both is a milky white to opaque white, and they do look a bit similar, they are not. (HDPE is milky white to almost translucent depending on thickness, and the Acetal materials are a more opaque white to slightly milky – once again depending on thickness .
What is acetal copolymer?
Acetal (Copolymer) is an engineering thermoplastic polymer that provides good strength and stiffness.
What is acetal plastic?
Acetal Plastic. Acetal (POM) – A thermoplastic produced by the addition polymerization of an aldehyde through the carbonyl function, yielding unbranched polyoxymethylene chains of great length.
