Acetal - Rod

Acetal Sheets and Acetal Rods (aka POM) acetal copolymer provides high strength and stiffness coupled with enhanced dimensional stability and ease of machining. Acetal is a general purpose, semi-crystalline engineered thermoplastics. Acetal is commonly used for parts that need to be stiff, and have low surface tension and good dimensional stability.
Acetal sheets and rods have low moisture absorption which gives excellent dimensional stability for close-tolerance machined parts. Because acetal absorbs minimal amounts of moisture, its physical properties remain constant in a variety of environments. Acetal copolymer overcomes the common problem of centerline porosity in large shapes of Acetal Homopolymer (aka Delrin).
Acetal is made in slightly different formulations variations sold under various trade names. Each Acetal manufactured use a range of recipes that are adjusted to improve specific properties. One of the most important differences between homopolymer acetal (POM-H) and copolymer acetal (POM-C) is porosity, porosity in plastics means it may contain small bubbles or voids. Copolymer acetals have little to no porosity at their centers. This makes them preferred acetal for food contact or medical applications.
Acetal Copolymer is preferred to Delrin® in high-pressure applications where centerline porosity is a concern.
