Acetal Rod

Acetal Rod

Acetal rod is a strong, rigid plastic with excellent impact and mechanical strength. It has low water absorption and is resistant to dilute acids, cleaning agents and numerous solvents. Acetal rod is easily machined and is commonly used in food contact applications. It is more resistant to hydrolysis and strong alkalis, and has a higher thermal expansion rate than acetal homopolymer (Delrin®). Acetal rod is available to buy online at PAR Direct by clicking the link above.
