Acetal, also known as Polyoxymethylene (POM), is a type of engineering thermoplastic that is widely used in various industries due to its desirable mechanical properties and ease of machinability. It’s particularly well-suited for producing machined parts.
- Mechanical Strength: Acetal exhibits excellent mechanical strength, allowing it to withstand high loads and stresses. It has good rigidity and can maintain its shape under heavy loads.
- Low Friction: Acetal has a low coefficient of friction, making it suitable for applications where sliding or rubbing contact is involved. This property reduces wear and extends the lifespan of machined parts.
- Wear Resistance: Its low friction and good wear resistance make acetal ideal for applications involving moving parts, such as gears, bearings, and bushings.
- Dimensional Stability: Acetal has excellent dimensional stability, which means it retains its shape and size over a wide range of temperatures and humidity levels.
- Chemical Resistance: Acetal is resistant to many common chemicals, solvents, and oils, enhancing its suitability for various industrial environments.
- Low Moisture Absorption: Acetal absorbs very little moisture, which helps maintain its mechanical and dimensional properties even in humid conditions.
- Machinability: One of the standout features of acetal is its ease of machinability. It can be easily cut, drilled, milled, turned, and fabricated using standard machining tools and techniques.
- Good Electrical Insulation: Acetal is an excellent electrical insulator, making it suitable for electrical and electronic applications.
- FDA Compliance: Certain formulations of acetal are approved by the Food and Drug Administration (FDA) for food contact applications, due to its low toxicity and chemical resistance.
- Gears and Bearings: Acetal’s low friction and wear resistance make it ideal for producing gears, bushings, and bearings in machinery and mechanical systems.
- Automotive Components: Acetal is used in various automotive applications, such as fuel system components, seatbelt parts, and window mechanisms.
- Medical Devices: Its biocompatibility and chemical resistance make it suitable for certain medical device components, especially when sterilization is required.
- Consumer Goods: Acetal is used in the production of zippers, snaps, and fasteners for clothing, as well as in various household items like plumbing components.
- Electrical Components: Due to its electrical insulation properties, acetal is used for insulating components in electrical and electronic devices
