Acetal Sheet, Rod, and Tube | Piedmont Plastics

Acetal Sheet, Rod, and Tube at Piedmont Plastics

Acetal, also known as polyoxymethylene (POM), is a high-performance engineering plastic valued for its excellent strength, stiffness, dimensional stability, and machinability. Available in both homopolymer (POM-H) and copolymer (POM-C) grades, acetal is widely used to manufacture precision components that require tight tolerances, low friction, and long-term wear resistance. Its combination of mechanical performance, moisture resistance, and ease of machining makes it a popular choice for demanding industrial and manufacturing applications.

Acetal sheet, rod, and tube are commonly used to fabricate gears, bearings, bushings, rollers, wear strips, conveyor components, valve parts, and other precision-machined components. Thanks to its durability and reliable performance, acetal is found throughout industries such as material handling, food processing, packaging, automotive, electronics, and industrial equipment manufacturing. Whether your application requires the enhanced mechanical properties of homopolymer acetal or the improved chemical and hydrolysis resistance of copolymer acetal, there is a grade designed to meet your performance requirements.

At Piedmont Plastics, we stock a wide range of acetal sheet, rod, and tube in both POM-H and POM-C grades to support your machining and fabrication needs. Our team can help you identify the right material based on your application requirements, operating environment, and performance goals.

Key Features of Acetal

Acetal is a versatile engineering plastic that combines strength, machinability, and wear performance, making it a popular choice for precision components and industrial applications.

High Strength and Stiffness: Excellent mechanical properties with superior room-temperature strength and stiffness in homopolymer (POM-H) grades.
Excellent Machinability: Easily machined into precision components with tight tolerances.
Low Friction: Naturally low coefficient of friction for smooth sliding and moving parts.
Wear Resistant: Outstanding resistance to wear in repetitive motion applications.
Moisture Resistant: Very low moisture absorption for consistent performance.
Chemical Resistant: Resistant to many fuels, solvents, lubricants, and industrial chemicals.
Good Electrical Insulation: Reliable electrical insulating properties.
Hot Water and Steam Resistant: Copolymer acetal (POM-C) performs particularly well in hot water, steam, and elevated-temperature environments.
Low Centerline Porosity: Copolymer acetal (POM-C) typically exhibits lower centerline porosity than homopolymer grades.
Good Dimensional Stability: Maintains tight tolerances across a wide range of operating conditions.

Benefits of Using Acetal

Acetal offers great strength, durability, and easy machinability, making it a popular material for precision parts. Its low friction, wear resistance, and resistance to moisture and chemicals help components last longer and perform reliably in demanding industrial environments.

Frequently Asked Questions

Acetal is a popular engineering material known for its strength, stability, and versatility. Below are some of the most frequently asked questions about acetal to help you better understand its properties, uses, and advantages.

Acetal (POM) is a high-strength engineering thermoplastic renowned for its stiffness, low friction, and excellent dimensional stability. It's widely used in precision parts requiring tight tolerances and durability.

There are two primary types of acetal. The first is homopolymer acetal (e.g., Delrin®), which offers slightly higher mechanical strength and stiffness but may exhibit centerline porosity. The second is copolymer acetal, which provides improved chemical resistance and reduced porosity, making it suitable for applications involving moisture or chemicals.

Homopolymer acetal (POM-H) offers higher strength, stiffness, and toughness. Copolymer acetal (POM-C) provides better performance in hot water, steam, and chemically demanding environments, while also exhibiting lower centerline porosity. The best choice depends on your application's operating conditions and performance requirements.

Delrin® is a brand name for homopolymer acetal, while generic acetal may refer to either homopolymer or copolymer types from other manufacturers.

Yes, certain grades of acetal plastic are FDA-compliant and suitable for direct food contact in processing and packaging equipment.

Acetal has better dimensional stability and machinability than UHMW, and absorbs less moisture than nylon, making it more stable in humid environments.

Yes, acetal is known for its excellent machinability. It can be easily cut, drilled, and milled to precise dimensions, making it ideal for custom parts requiring tight tolerances. Piedmont Plastics can cut acetal to size and assist with fabrication upon request.
