What type of plastic is Polyoxymethylene?
thermoplastic
Acetal plastic, also called polyacetal and polyoxymethylene (POM), is a general purpose, semi-crystalline, engineered thermoplastic. Acetal is commonly used for parts that need to be very stiff, have low surface friction and good dimensional stability.
What is Polyoxymethylene made of?
Polyacetal, also commonly known as acetal or polyoxymethylene (POM), is a formaldehyde-based, semi-crystalline engineering thermoplastic which contains the functional group of a carbon bonded to two -OR groups. It is 100% recyclable.
Is Polyoxymethylene a plastic?
Polymeric Materials—Structure, Properties, and Applications Polyoxymethylene is an important engineering plastic. It is being used for the production of a large number of engineering components due to its following properties: Excellent short-term mechanical properties such as tensile strength, toughness, and rigidity.
Is Polyoxymethylene the same as Delrin?
What Kind of Plastic is Delrin? Delrin is the trademark name for a series of acetal resins which are semi-crystalline thermoplastic polymers which are also known by the abbreviation POM or polyoxymethylene. It’s a general-purpose engineering thermoplastic.
Is polyoxymethylene heat resistant?
Polyoxymethylene (POM) is highly crystalline and is available in copolymer and homopolymer grades….Polyoxymethylene.

Is polyoxymethylene safe?
On the basis of the data, it is concluded that Polyoxymethylene Urea is safe for use as a cosmetic ingredient. A previous determination, however, that the concentration of free formaldehyde in cosmetic formulations should not exceed 0.2% was considered appropriate for this ingredient as well.
Is polyoxymethylene toxic?
26,27 Polyoxymethylene brackets release formaldehyde, which is toxic, allergenic, and potentially carcinogenic.
Is polyoxymethylene flammable?
It is a flammable liquid and dangerous fire hazard. Advantages -Highly crystalline – More creep resistant than Nylon. – Good resistance to solvents (except phenols). – Low smoke emission.
What is polyoxymethylene urea?
Abstract: Polyoxymethylene Urea is a variable molecular weight polymer formed in stages from the condensation reaction of urea with formaldehyde. It is used in a wide range of cosmetic formulations as a bulking agent and to form the outer shell of microcapsules.
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.
What are the properties of polyoxymethylene?
Polyoxymethylene is an important engineering plastic. It is being used for the production of a large number of engineering components due to its following properties: Excellent short-term mechanical properties such as tensile strength, toughness, and rigidity.
What is polyoxymethylene plastic used for?
Polyoxymethylene is a blend of plastic used in many types of injection molding applications. Since it is a high strength plastic, Polyoxymethylene is often favored for its high impact strength and hardness level, exceptional durability, and high flexural modulus. Other benefits of using Polyoxymethylene products include:
What is polyoxymethyene resin?
The reaction is followed by purification of the trioxane by distillation or extraction to remove water and other active impurities containing hydrogen. Polyoxymethyene resins demonstrate well-balanced properties ranging for mechanical to physical and flammability performance.
What is polyoxymethylene injection molding?
Polyoxymethylene is a blend of plastic used in many types of injection molding applications. Since it is a high strength plastic, Polyoxymethylene is often favored for its high impact strength and hardness level, exceptional durability, and high flexural modulus.
