Differences
Delrin is a homopolymer grade, this means that there
are advantages and disadvantages over Acetal Rod.
Advantages
Acetal Rod is more suited to the more mechanical
applications where an easy to machine and high
quality surface finish is required. It is potentially
harder wearing than Acetal and is often used in the
manufacture of gears or even motorcycle crash pegs.
Disadvantages
POM rod is not suitable for food contact applications
and has less resistance to chemical attack. It also
has a lower size range availability and can be
slightly more expensive.
Applications
POM Rod is suitable for most non food and non highly
abrasive component applications. Because POM does not
absorb very much moisture, it is an engineering
plastic that will suit marine applications as it also
has a very low friction co-efficient and possesses
exceptional sliding abilities. POM is also very good
for manufacturing of many gears, because it is very
good to machine and has mechanical strength and
provides long life and quiet operation.
