❓ What is POM Rod (Polyacetal Rod)?
POM Rod or Polyoxymethylene Rod is an engineering thermoplastic material also known as Polyacetal or Acetal. 🧪 This material is one of the most precise engineering plastics with outstanding characteristics such as high stiffness, exceptional wear resistance, and superior dimensional stability. POM Rod is produced through a precision extrusion process that results in cylindrical rods with tight tolerances.
The main composition of POM Rod is formaldehyde copolymer that provides an optimal combination of mechanical strength and chemical resistance. This material has natural self-lubricating properties that make it ideal for moving applications without lubrication. Other outstanding characteristics include creep resistance, good impact strength, and the ability to maintain mechanical properties in various environmental conditions.
The main advantages of Polyacetal Rod compared to other materials are its ability to maintain dimensional precision under continuous load, resistance to various industrial chemicals, and wear resistance comparable to some metals. The material also has temperature resistance up to +100°C and a low friction coefficient, making it ideal for precision applications.

🚀 Product Advantages
High Precision - Our POM Rod has a diameter tolerance of ±0.05mm that ensures accuracy for precision machine applications. In our tests, rod straightness reaches 0.1mm per 1000mm length.
Exceptional Wear Resistance - Our material has 50% better wear resistance than nylon in dry friction applications. In pin-on-disk testing, wear is only 2-5mg per hour of operation.
Superior Dimensional Stability - With near-zero water absorption (0.2%), our product maintains perfect dimensional stability in humid environments. Dimensional change <0.1% at 100% humidity.
Ease of Machining - Our material can be easily fabricated to produce smooth surfaces (Ra <0.8μm) using conventional machine tools. Does not produce sharp chips when cut.
