POM Sheet and POM Rod are high-performance engineering plastics made from polyoxymethylene. Known in the industry as acetal plastic, POM material, or acetal copolymer/homopolymer, they are widely used in precision manufacturing due to their outstanding strength, wear resistance, and excellent dimensional stability.
There are two main types of POM materials:
• POM-H (Homopolymer): Higher mechanical strength and rigidity
• POM-C (Copolymer): Better chemical resistance and thermal stability
POM Sheets and POM Rods are ideal for components requiring tight tolerances, smooth operation, and long service life.
Key Properties of POM Sheets and POM Rods
1. High Mechanical Strength and Rigidity
POM material provides excellent tensile strength and impact resistance. It resists deformation under load, making it suitable for structural parts such as gears, bushings, and mechanical connectors.
2. Excellent Wear Resistance and Low Friction
The low friction coefficient reduces wear and noise. POM Sheet and rod products are widely used for sliding components, ensuring smooth movement and longer lifespan even without lubrication.
3. Superior Dimensional Stability
Low shrinkage and high dimensional accuracy allow POM to maintain shape in precision machining. It performs consistently in both long-term use and high-precision assembly environments.
4. Chemical and Moisture Resistance
• Resistant to fuels, oils, and many industrial chemicals
• Extremely low moisture absorption
• Suitable for humid and corrosive environments
POM is also available in FDA-approved grades for food contact applications.
5. Reliable Temperature Resistance
Typical working range: -40°C to +120°C
Short-term peak resistance up to approximately 160°C.
Thermal stability ensures performance in automotive and industrial environments.
Common Applications of POM Sheets and POM Rods
• Automotive: gears, bearings, fuel system components, door and window mechanisms
• Industrial equipment: pulleys, rollers, conveyor components, pump parts
• Food processing machinery: FDA-compliant sliding components, wear plates, cutting parts
• Consumer electronics: precision gears, switches, housings
• Precision engineering: CNC-machined spacers, fixtures, measuring tools
POM is often used as a lightweight alternative to metal where equivalent performance is required.
How to Select the Right POM Sheet or POM Rod
Before purchasing, evaluate the following criteria:
• Material type: POM-H for high strength, POM-C for chemical resistance
• Dimensions: thickness, diameter, and machining allowance
• Operating conditions: load, speed, wear requirements
• Temperature and chemical exposure
• Certification requirements: FDA, ROHS, REACH, etc.
Accurate selection helps optimize performance and reduce production cost.
Tips for Machining POM Sheets and POM Rods
• Use sharp carbide cutting tools to ensure smooth surfaces
• Maintain moderate cutting speed to prevent heat buildup
• Apply coolant when drilling or milling
• Securely clamp the workpiece to ensure precision
• Consider edge rounding to avoid stress concentration
POM’s machinability makes it a preferred material for CNC and turning processes.
