Properties And Applications of POM Material Sheets And Bars



Polyoxymethylene (POM), also known as acetal resin, is a widely used engineering plastic. POM material sheets and bars possess several remarkable characteristics and find extensive applications in various industries.


I. Characteristics


  1. Superior mechanical properties:
    • POM sheets and bars exhibit high strength and stiffness, ranking among the top engineering plastics.

    • They have excellent fatigue resistance, remaining stable under repeated stress.

    • Outstanding creep resistance ensures minimal dimensional changes under long-term loading.

  2. Unique friction properties:
    • With a low friction coefficient, POM has good self-lubricating properties and can operate effectively without lubrication.

    • High wear resistance enables it to withstand abrasion for a long time, prolonging its service life.

  3. High chemical stability:
    • POM is resistant to organic solvents, oils, weak acids, and weak alkalis.

    • However, it is not resistant to strong acids and strong oxidants.

  4. Good dimensional stability:
    • Low molding shrinkage rate and high processing precision make it suitable for manufacturing precision parts.

  5. Excellent electrical properties:
    • POM has high insulation resistance and dielectric strength, making it applicable in the electrical field.

  6. Moderate temperature resistance:
    • The long-term service temperature is generally between -40°C and 100°C.


II. Applications


  1. Mechanical field:
    • POM sheets and bars can be used to manufacture various mechanical transmission components such as gears, bearings, cams, and couplings.

    • In the fields of automation equipment and instrumentation, they can serve as structural parts and wear-resistant parts.

    • They are suitable for making sliding guides and sliders, taking advantage of their low friction coefficient and high wear resistance.

  2. Automotive industry:
    • POM can be used to produce various interior parts of automobiles, such as door lock systems, window regulators, and seat belt components.

    • Due to its dimensional stability and fatigue resistance, it can also be used for parts around the automobile engine.

  3. Electrical and electronic field:
    • POM can be used to make gears, cams, switch parts, etc. for electrical appliances.

    • It can also be used as the housing and insulating parts of electronic equipment.

  4. Industrial field:
    • In the chemical, food processing and other industries, POM can be used to manufacture corrosion-resistant and wear-resistant parts such as pump bodies, valves, and pipes.

    • As guides and idlers for logistics conveying equipment.
