What is the material pom?
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.
What is hostaform material?
Hostaform®/Celcon® acetal copolymer (POM) possesses a linear structure with a highly crystalline quality that provides a variety of characteristics: outstanding wear, long-term fatigue, toughness and creep resistance as well as excellent resistance to moisture, solvents and strong alkalis.
What is hostaform C?
Hostaform® C 9021 14 BLACK is a crystalline polyacetal polyoxymethylene (POM) copolymer. Exhibits good resistance to chemicals (solvents, fuels & strong alkalis), wear, long-term fatigue, creep, hydrolysis, stress cracking, thermal and oxidative degradation.
What is the difference between a copolymer and terpolymer?
A terpolymer is a type of polymer that is made of three different monomers. The key difference between copolymer and terpolymer is that copolymers are polymers consisting of more than one type of repeating units, whereas terpolymers are a type of copolymers that consists of three different types of monomers.
Is POM toxic?
Is POM toxic? In solid form, no. In fact, Acetal is often used in food processing equipment and manufacturing. Acetal can be toxic if inhaled and/or absorbed into the skin or eyes as a vapor or liquid.
Is POM same as nylon?
Nylon is ideal as a filament for 3D plastic printing, but it absorbs water over time. POM is a type of acetal resin, used to make Dupont’s Delrin, a valuable plastic for gears, screws, wheels and more. POM has high flexural and tensile strength, stiffness and hardness.
Who makes Celcon M90?
This product is manufactured by Celanese in Florence, KY and Bishop, TX, U.S.A. ISO 9001:2008, FDA, UL, NSF and USP Class VI.
What is acetal give example?
Acetal Examples Dimethoxymethane is an acetal compound. Acetal is also a common name for the compound 1,1-diethoxyethane. The compound polyoxymethylene (POM) is a plastic that is also called simply “acetal” or “polyacetal.”
Where can I find the datasheet of Hostaform® C 2521 from Celanese?
This datasheet of HOSTAFORM® C 2521 from Celanese is provided by the international plastics database CAMPUS .
What is the difference between Hostaform®pom C 9021 and C 2521?
The other basic grades have comparable hardness, except the grades C 2521 and M30AE, based on the low molecular weight POM. The reinforced grades have a higher ball indentation hardness than Hostaform®POM C 9021 while the high-impact grades possess lower hardness.

What are the basic grades of Hostaform®pom?
3.1.3.1 Hostaform®POM basic grades The glass transition temperature of the Hostaform® POM base polymer (from-60 to -65 °C) is low compared to that of other plastics. This explains its remarkably high-impact strength even at low temperature.
