POM-homopolymer (POM-homo)
Description (definition)
POM homopolymer (polyoxymethylene homopolymer) is an engineering plastic produced from the polymerization of formaldehyde. It is characterized by high strength, rigidity, low coefficient of friction and excellent wear resistance. Compared to the POM copolymer (POM-Copo), POM-Homo offers higher mechanical strength and hardness, but is less resistant to chemicals. It is often used in precision parts, technical components and industrial applications.
An example
A typical example of POM homopolymer is the manufacture of gears and bearings in machines. Thanks to its high wear resistance and low friction, POM homopolymer ensures long-lasting and low-noise operation.
What advantages does POM homopolymer offer over POM copolymer?
POM-Homo has higher strength, hardness and a better modulus of elasticity than POM-Copo. This makes it particularly suitable for applications subject to high mechanical stress, while POM-Copo offers better chemical resistance and thermal stability.
Where is POM homopolymer preferred?
POM-Homo is used in the automotive industry for fuel components and bearings, in electronics for connectors and switches and in industry for precision parts such as gear wheels and pump components.
How sustainable is POM homopolymer?
POM-Homo is recyclable, but the process is demanding. Recycled material is often used in less critical applications. However, the long-lasting use of POM-Homo in technical products helps to conserve resources.
