How Is POM Plastic Different From Other Engineering Plastics? How To Choose The Material Suitable For Your Own Use?

1. What is POM?

 

POM plastic, also known as polyoxymethylene or acetal plastic, is a high-performance engineering thermoplastic material. It is a type of thermoplastic that is resistant to chemical and creep deformation.

 

POM plastic is available in two forms: homopolymer and copolymer. Homopolymer POM plastics have high stiffness and impact strength, while copolymer POM plastics have better resistance to stress cracking, chemical resistance, and thermal stability.

 

2. How is POM plastic different from other engineering plastics?

 

POM plastic, also known as acetal plastic, is a high-performance engineering thermoplastic that has unique properties when compared to other engineering plastics. Here are a few key differences:

 

Mechanical properties: POM plastic has a high strength and stiffness, as well as a low coefficient of friction. This makes it an excellent material for use in applications that require durability and wear resistance, such as gears, springs, bearings, and other moving parts.

 

Machinability: POM plastic is easy to machine and has good dimensional stability, which makes it a preferred material for precision parts that require tight tolerances.

 

Chemical resistance: POM plastic has high resistance to chemicals and solvents, including motor oil and gasoline. This makes it a popular choice for use in automotive and mechanical applications.

 

Moisture resistance: POM plastic is highly resistant to moisture and has a low water absorption rate compared to other plastics, which makes it a suitable material for applications that require good dimensional stability in humid environments.

 

Thermal properties: POM plastic has a high melting point and can withstand temperatures up to 140°C, making it suitable for high-temperature applications.

 

 

3. How to choose the material suitable for your own use?

 

When selecting a material suitable for your own use, it's essential to consider the specific requirements of your POM application. Here are some factors to consider:

 

Mechanical properties: Consider the strength, stiffness, and toughness required for your application.

 

Thermal properties: Determine the temperature range your application will operate in and select a material that can withstand these temperatures.

 

Chemical resistance: Determine the type of chemicals or solvents the material will come in contact with and select a material that is compatible.

 

Environmental impact: Evaluate the impact of the material on the environment, and consider if there are more sustainable or environmentally-friendly options available.

 

Cost: Review the cost of the material, including manufacturing, processing, and disposal costs.

 

Availability and ease of processing: Consider the availability of the material and ease of processing, such as forming, machining, and molding.

 

By taking these factors into account, you can choose the most appropriate material for your application. It's always a good idea to consult with material suppliers or manufacturers to help determine the best option for your specific needs.
