Acetal: The Metal Industry's Worst Nightmare

It seems metal has been used in a variety of applications since the beginning of time, yet acetal polymers have only been commercially available since the 1960s. With such a short history compared to that of metal, is it a bit premature to assume that acetal can make an entire industry quake in fear? Possibly - but it shouldn’t be unreasonable to analyze how this thermoplastic material could be used to replace metals in some key industrial and commercial applications. It’s time for acetal to take the spotlight so we can better understand why this article’s title doesn’t seem entirely outrageous.   

What is Acetal?

Acetal is a unique plastic material that was designed to replace metal in a variety of applications. Using technical terms, acetal shapes are produced from both copolymer and homopolymer resins, which provide a high ratio of elasticity coupled with great strength, stiffness, and toughness. Acetal is characterized by having a low coefficient of friction and good bearing characteristics.

Acetal absorbs minimal amounts of moisture, keeping its physical properties constant in a variety of environments. Lastly, acetal has a high melting point, allowing it to be continuously exposed to temperatures ranging from 160°F to 185°F.

Is Acetal More Cost-Effective Than Metal?

If you’re looking for a cost-effective solution, opting for acetal in your projects will undoubtedly help you financially. One factor to analyze is how much lighter acetal is compared to an equivalent piece of metal. When you commit to using acetal in your projects instead of a heavy metal, you will begin to see significant cost reductions associated with:

• Energy consumption

• Fuel efficiency

• Logistics

• Maintenance and installation

When determining design capability, metal becomes more costly as the design becomes more complex due to the need to weld, bend, or grind the material. Alternatively, acetal’s thermoforming capability has a relatively minimal impact on costs and allows for a variety of customization.

What is Acetal Used For?

From precision mechanical components like gears and bearings to fluid-handling systems and consumer products, acetal delivers reliable performance in demanding environments. Its low friction, high dimensional stability, and resistance to chemicals and moisture ensure durability and efficiency, making it a popular choice for manufacturers seeking high-performance solutions.
