Polyoxymethylene storage modulus range

What are the properties of polyoxymethylene (POM)?

POM is known for its high stiffness, excellent dimensional stability, low friction, and good wear resistance. The following table provides a comprehensive list of polyoxymethylene (POM) properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).

Which parameter affects the final structure and Young's modulus of low molecular weight POM?

Statistical analysis showed that the parameter that has the greatest impact on the final structure and the Young's modulus of low molecular weight POM is the mold temperature associated with the improved crystallization. Further increases with rising mold temperature can be expected.

What is the failure mode of polyoxymethylene composite?

The failure mode of the composite was supposed to be the deformation and destruction of POM matrix around the interfacial layer under load. This work is supported by Ph.D. Programs Foundation of Education Ministry of China for new teacher (20100181120018). Structural changes in non-isothermal crystallization process of melt-cooled polyoxymethylene.

What is a polyoxymethylene syringe used for?

couplings, conveyor links. -Medical: Insulin syringe, powder inhaler. Polyoxymethylene (hom.) Polyoxymethylene is a semi-crystalline thermoplastic polymer that is also known as polyacetal. POM is available as a homopolymer and as copolymer with oxyethylene groups for improved thermal stability.

What is the tensile strength of Pom samples?

The tensile strength of POM samples was measured with a 4302 material testing machine from Instron Co. (USA) according to ISO527/1-1993 (E). Five samples were tested, and the test speed was 50 mm/min, while the sample length between benchmarks was 25 mm. 2.3.2. Polarized light microscope analysis

Is polyoxymethylene acetal or polyformaldehyde?

Polyoxymethylene (POM), also known as acetal, polyacetal, and polyformaldehyde, is a high-performance engineering thermoplastic. It is a type of polymer with a repeating unit composed of formaldehyde, and it belongs to the family of polyoxymethylenes.
