High-Precision Engineering Material for Demanding Applications
POM plastic (Polyoxymethylene), also known as acetal or polyacetal, is a high-performance thermoplastic engineered for precision parts and long-term durability. Available in copolymer (POM-C) and homopolymer (POM-H) variants, it offers excellent mechanical strength, wear resistance, and low moisture absorption.
Key Features of POM Plastic
- Food Grade Approved: Suitable for applications involving direct food contact (EU Regulation 1935/2004).
- Dimensional Stability: Low water absorption, maintains shape in humid environments.
- High Mechanical Performance: Strong, rigid, and impact-resistant for precision parts.
- Wear and Chemical Resistance: Withstands friction, fuels, and a wide range of chemicals.
- Alternative material: In many areas, polyacetal (POM) can replace polyamide (PA).

Applications of POM Polyacetal
- Manufacturing: Ideal for gears, bushings, and pump components. High stiffness and wear resistance make it suitable for industrial applications requiring precision and long service life.
- Food Processing: Complies with EU food contact regulations. Used for parts in conveyor systems, packaging machines, and cutting tools. Easy to clean and highly durable.
- Automotive: Resistant to fuels, oils, and temperature fluctuations. Commonly used in fuel systems, valves, and connectors due to its dimensional stability and chemical resistance.
