Acetal is a highly crystalline form of polymerized formaldehyde noted for its strength, stiffness, and toughness. Acetal also has a very low coefficient of friction and good bearing characteristics, giving acetal products many highly desired capabilities. Acetal sheets, rods, and strips are produced from copolymer (Celcon) or homopolymer (Delrin) resins. With these excellent physical characteristics, many industries rely on acetal in their machinery. This is typical in manufacturing environments where equipment has rollers.
Why Choose Acetal Plastic for Industrial Applications?
Acetal plastic is widely used in industrial and manufacturing applications because of its strength, low friction performance, and excellent dimensional stability. Acetal sheets and rods are commonly used for rollers, bearings, bushings, gears, conveyor components, and precision-machined parts that require durability and tight machining tolerances.
The physical properties of acetal remain constant in a variety of environments as it absorbs only minimum amounts of moisture. An acetal roller can hold up under the most challenging conditions. In high-moisture environments, acetal bearings can outperform nylon by 4 to 1. However, under conditions of average humidity, nylons are superior to acetals in impact strength and abrasion resistance. The dimensional stability of acetal sheet and rod allows for close tolerance machining of parts.

Acetal generally offers better dimensional stability and lower moisture absorption, while nylon typically provides better impact strength and abrasion resistance. The best material depends on the operating conditions and application requirements.
Acetal is widely used for precision-machined components because it maintains tight tolerances during machining. Its dimensional stability and clean machining characteristics make it ideal for gears, bushings, rollers, and custom industrial parts.
Yes. Acetal is designed for demanding industrial environments and performs well under repeated mechanical stress, exposure to humidity, and continuous operation in manufacturing and processing applications.
