Precision Acetal Washers Manufactured in the UK
Bluemay Weston manufactures precision acetal washers to standard and bespoke specifications for customers across a wide range of industries. Produced using our punching and water jet cutting capabilities, acetal washers can be supplied in small development quantities through to high-volume production runs.
Acetal, also known as POM or polyacetal, is a strong engineering plastic valued for its dimensional stability, low moisture absorption and low-friction characteristics. These properties make acetal washers a practical choice for mechanical, electrical, automotive, aerospace and general industrial applications.
Stable, Low-Friction Engineering Plastic Washers
Acetal washers provide a strong combination of stiffness, wear resistance and dimensional stability. Unlike some alternative plastics, acetal has low moisture absorption, helping components retain their shape and performance in applications where accuracy and consistency are important.
The naturally low-friction surface of acetal also makes it effective where smooth movement, reduced wear or reliable spacing is required. Acetal washers are frequently specified for mechanical assemblies, sliding components, bearing surfaces and applications where a lightweight alternative to metal is preferred.

Frequently Asked Questions About Acetal Washers
Acetal washers are used in applications where dimensional stability, wear resistance and low-friction performance are required. They are commonly found in mechanical assemblies, electrical components, automotive parts, aerospace components, industrial machinery and precision spacing applications.
Acetal is a strong engineering plastic also known as POM or polyacetal. It is valued for its stiffness, dimensional stability, low moisture absorption and low-friction characteristics, making it suitable for precision engineering components.
Acetal washers can typically operate within a temperature range of approximately -40°C to +100°C, although this can vary depending on the grade of material, load, environment and application. For higher temperature requirements, an alternative material may be more suitable.
Acetal offers good resistance to many fuels, solvents and industrial fluids, but it is not suitable for every chemical environment. Applications involving strong acids, strong alkalis or aggressive chemicals should be reviewed before specifying acetal washers.
Acetal has good electrical insulating properties and can be used in electrical assemblies where non-metallic spacing, separation or insulation is required. The final suitability will depend on the design, voltage and operating environment.
Yes. Bluemay Weston manufactures acetal washers in both standard and bespoke sizes. Components can be produced to customer drawings, dimensions or samples using punching and water jet cutting techniques.
Acetal washers generally offer lower moisture absorption and better dimensional stability than nylon washers. Nylon washers can be tougher and more flexible in some applications, whilst acetal is often selected where close tolerances, low friction or consistent shape retention are important.
Acetal has low water absorption and retains its dimensions well in many damp or humid environments. This makes acetal washers suitable for applications where moisture exposure may affect the performance of some other plastic materials.
Yes. Acetal is often used for moving or sliding components because of its low-friction properties, stiffness and wear resistance. It can be a suitable material for thrust washers, bearing washers and mechanical spacing applications.
Bluemay Weston can manufacture acetal washers in quantities ranging from prototypes and small development batches through to high-volume production runs of many thousands or millions of components, depending on customer requirements.
