In the world of modern manufacturing, where tolerances are tighter and margins for error are narrower, selecting the right material is not just a technical decision but a strategic one. Polyacetal, also known as POM (Polyoxymethylene), has become a trusted material across automotive, electronics, industrial automation and consumer products. At Surlon, we work with polyacetal every day. Here’s why engineers, designers and manufacturers continue to specify it in the most demanding applications.

What Is Polyacetal?

Polyacetal (POM) is a high-crystalline engineering thermoplastic known for:

• Excellent dimensional stability
• Low coefficient of friction
• High wear resistance
• Strong mechanical strength
• Resistance to fuels, oils, and moisture

It’s commonly used in precision components that require consistent, long-term performance.

Polyacetal stands out among engineering plastics because of its unique combination of dimensional stability, machinability and low friction performance. It maintains its shape and structural integrity even in environments with fluctuating temperatures and humidity, a crucial factor in high-tolerance components. Its naturally low coefficient of friction and excellent wear resistance make it ideal for moving parts that operate without lubrication. Unlike many polymers, polyacetal is also highly machinable, producing clean finishes and holding tight tolerances with minimal tool wear. These qualities make it especially valuable in CNC machined parts, gears and sliding mechanisms where consistency, repeatability, and durability are non-negotiable.

Key Applications:
Polyacetal is widely used across industries that demand reliable, high-precision parts. In automotive and industrial automation, it’s found in components like gears, bushings, actuators, and rollers due to its durability and low-friction performance. It’s also trusted in electronics and food-grade environments for its machinability, dimensional stability, and clean operating profile.

Performance and Sustainability:
Polyacetal is valued for long part life and low maintenance. While not biodegradable, it is recyclable, and its durability reduces the need for frequent replacements — helping reduce long-term waste and cost.

If you need a material that’s lightweight, machinable, stable and durable polyacetal delivers. Whether you’re designing components for motion, precision, or endurance, it continues to outperform traditional materials.

Precision starts with the right polymer.
