POM copolymer (POM-copo)
Description (definition)
POM copolymer (polyoxymethylene copolymer) is an engineering plastic produced by the copolymerization of formaldehyde with additional monomers. This modification gives POM copolymer improved chemical resistance, thermal stability and reduced susceptibility to stress cracking compared to POM homopolymer. It is often used in applications that require a combination of precision, durability and resistance to aggressive chemicals.
Example
A typical example of POM copolymer is its use in pump housings and valves that are exposed to aggressive chemicals or moisture. POM-Copo offers excellent stability and durability in these environments.
What advantages does POM copolymer offer over POM homopolymer?
POM-Copo has better chemical resistance, especially to alkalis and acids, as well as greater stability under moisture and thermal stress. However, it is slightly less mechanically strong than POM-Homo.
Where is POM copolymer preferably used?
POM-Copo is used in the automotive industry for fuel systems and seals, in medical technology for sterilizable instruments and in industry for precision parts that are exposed to chemical stresses.
Is POM copolymer recyclable?
Yes, POM-Copo can be recycled. However, the recycling process is technically challenging as the material properties must be retained. Recycled POM-Copo is often reused in less critical applications.
