Acetal (POM-C) Rod
Acetal copolymer (POM-C) is often referred to generically as Delrin®. It absorbs very little moisture, is dimensionally stable and very easy to machine, and is widely used for precision machine parts.

Material and sizes
POM
White and black. An engineering plastic with high dimensional stability that is very easy to machine. It absorbs little moisture and has good stiffness, fatigue strength and sliding properties, making it suitable for close-tolerance precision parts. As a copolymer it is more resistant to hot water and alkaline media than homopolymer POM; it is not resistant to strong acids.
Delrin® is a registered trademark of Delrin.

Frequently asked questions
Is Delrin the same as POM?
Delrin® is the trade name of an acetal homopolymer (POM-H), and the name is widely used in the market for POM in general. The copolymer (POM-C) performs equally well in most applications; if you have a specific requirement, simply state it when ordering.
Why can the invoiced weight differ from the calculated weight?
The calculator gives the theoretical weight. The actual weight varies with dimensional tolerances and cutting allowance; we invoice on the actual weight as weighed.
What information should I send for a quote?
We only need the size (diameter × length), quantity and delivery location. If you fill in the calculator above, these details are added to the WhatsApp message automatically.
