Acetal (POM-C) Rod

Description

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.

Key Features

High impact resistance and durability.
Superior dimensional stability and surface hardness.
Excellent dielectric strength and solvent resistance.
Low moisture absorption for reliable performance.
Suitable for high-temperature water applications (Copolymer grades).

Applications

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.

Frequently Asked Questions

What is acetal rod (POM-C) and what is it used for?

Acetal rod, also known as POM-C, is an engineering plastic used for precision machined parts. It’s commonly used for gears, bushes, rollers, wear strips, and valve components. POM-C offers good strength, low friction, and dimensional stability, making it suitable for mechanical and industrial applications.

What are the key material properties of POM-C acetal rod?

POM-C acetal rod has high stiffness, good impact resistance, low moisture absorption, and excellent machinability. It provides low friction and good wear resistance, making it suitable for moving parts. Compared to POM-H, POM-C has better chemical resistance and more consistent density across the 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?

POM-C acetal rod is durable under repeated mechanical stress and performs well in wear and sliding applications. It maintains dimensional stability over time and resists fatigue. While strong, it is not designed for high-temperature structural loads and should be used within its recommended operating limits.

Does acetal rod require any special maintenance?

Acetal rod requires minimal maintenance. It does not absorb much moisture and does not need sealing or coating. Parts should be kept clean and free from abrasive contaminants to maximise wear life. Lubrication is often unnecessary due to its naturally low friction surface.

Is POM-C acetal rod resistant to chemicals and moisture?

POM-C has good resistance to fuels, oils, greases, and many solvents. It also has very low moisture absorption, which helps maintain dimensional accuracy. It is not suitable for strong acids, oxidising agents, or prolonged exposure to high temperatures or UV without protection.
