Why POM for precision parts
Polyoxymethylene combines mechanical strength with machinability — the ideal engineering plastic for high-wear, low-friction components. This is why we recommend POM for most custom CNC machining POM parts in China.
Exceptional wear resistance
POM exhibits outstanding abrasion resistance and maintains its dimensional integrity under continuous sliding contact. Ideal for gears, bushings, and conveyor components that endure repetitive motion and high cycle loads.
Low wear rateSelf-lubricating low friction
The inherent low coefficient of friction (0.15–0.35 against steel) enables POM parts to operate with minimal lubrication, reducing maintenance costs and extending service life in bearing and guide applications.
μ = 0.15–0.35Outstanding dimensional stability
Low moisture absorption (0.2–0.3% at 23°C / 50% RH) and minimal creep under load ensure that POM components retain their critical dimensions across varying temperature and humidity conditions.
Moisture < 0.3%Broad chemical resistance
POM resists attack from hydrocarbons, fuels, solvents, and many dilute acids and alkalis. This makes it a trusted choice for automotive fuel systems, chemical processing equipment, and industrial fluid-handling components.

Global POM material grade references
POM is specified under various international standards. We work with all major grade designations to ensure your custom CNC machining POM parts in China meet local and global material requirements.
ASTM (USA)
Standard designations: POM-H (homopolymer) and POM-C (copolymer). Commonly referenced grades include 150, 170, and 270 series for general-purpose and high-toughness applications. These grades are widely used in automotive and consumer goods.
ASTM D4181 / D6778ISO (Europe)
Specified under ISO 9988-1 with designations such as POM-H and POM-C. European standards emphasize thermal stability and long-term creep resistance. Common types include 9114, 9124, and 9024 for injection molding and extrusion.
ISO 9988-1JIS (Japan)
Japanese Industrial Standards define POM grades with prefix "POM" followed by numeric indicators for viscosity and property modifications. Commonly used grades such as M90, M270, and NW-02 are recognized for their excellent dimensional accuracy and surface finish.
JIS K 6744GB (China)
Under the Guobiao standard, POM is designated with prefix "POM" and grade numbers like M90, M270, and N2320. These materials are cost-effective and widely available, meeting the mechanical requirements for most industrial components manufactured locally.

The technical backbone of every component — key performance indicators that define POM's suitability for precision engineering applications.
High mechanical strength
Tensile strength up to 70 MPa and flexural modulus up to 2,800 MPa provide excellent load-bearing capacity. POM maintains its stiffness across a wide range of temperatures, outperforming many other engineering plastics.
Tensile > 60 MPaExcellent fatigue resistance
POM demonstrates outstanding endurance under cyclic loading, with a fatigue strength of approximately 35 MPa at 10⁷ cycles. This makes it ideal for springs, clips, and other dynamically stressed components.
35 MPa @ 10⁷ cyclesLow moisture absorption
Equilibrium moisture content of only 0.2–0.3% ensures that dimensional changes due to humidity are minimal. Parts remain stable in both dry and humid operating environments without significant swelling or loss of properties.
Absorption < 0.3%Wide operating temperature
POM retains useful mechanical properties from –40°C to +120°C, with a heat deflection temperature (HDT) of approximately 110°C at 1.82 MPa. Suitable for under-hood automotive and outdoor applications across seasonal extremes.
