- C.L. – Chemically lubricated for smoother performance.
- A.F. – PTFE ( Teflon ®) filled for enhanced wear resistance.
- G.F. – Glass-filled (up to 30%) for improved strength.
- E.L. – Electrically conductive for specific applications.
- S.D. – Static dissipative for handling sensitive electronics.
Acetal Rod offers excellent impact resistance, dimensional stability, and high mechanical strength. With natural lubricity and a hard surface, they provide durability and wear resistance in demanding applications. Their low moisture absorption ensures consistent performance, and they can withstand temperatures from -45°C to +100°C without losing strength.
Acetal rods are widely used in the food industry (though not all grades are F.D.A.-approved) and in manufacturing components like bearings, gears, bushings, and wear-resistant parts.
Custom-coloured rods are available upon request, tailored to your specifications.

Frequently Asked Questions
What is acetal rod (POM-C) and what is it used for?
What are the key material properties of POM-C acetal rod?
What sizes and diameters are available for acetal rod?
Acetal rod is available in a wide range of diameters, typically from small precision sizes up to large engineering diameters. Lengths are usually supplied in standard rods, often around 1 metre. Availability depends on diameter and stock. Cut-to-length options are commonly available for machining and fabrication needs.
Is acetal rod easy to machine and fabricate?
Yes. POM-C acetal rod machines easily using standard metalworking tools. It can be turned, milled, drilled, and tapped with clean results and minimal tool wear. It produces tight tolerances and smooth surface finishes, making it suitable for CNC machining and manual workshop fabrication.
How durable is POM-C acetal rod in industrial applications?
Does acetal rod require any special maintenance?
Is POM-C acetal rod resistant to chemicals and moisture?
Can I use your acetal rod where the drawing says Ertacetal C or Acetron?
Need this custom cut or fabricated?

Plastic Wear Parts for Conveyor Belts: Materials, Applications, and Buying Guide
Conveyor Belts Conveyor belts fail for one simple reason: wear. Friction, abrasion, impact, moisture, and contamination slowly destroy metal components and belts, driving up downtime and maintenance costs. That is why plastic wearable parts on conveyor belts are now standard across food processing, packaging, mining, recycling, and manufacturing lines. This guide breaks down where plastic […]
