This copolymer acetal grade, containing a metal detectable additive, has been specifically tailored for use in the food processing and packaging industries where it can easily be traced by the conventional metal detection systems installed to detect contamination of the foodstuffs (results may vary depending on the sensitivity of the metal detection system used). Metal Detectable Acetal presents good mechanical strength, stiffness and impact strength, and it also features a food contact compliant composition.

Until now, when a food processor or other manufacturer needed a means of detecting the presence of foreign substances in the product, they had no choice but to use highly visible colored materials for their plastic parts. Metal detectable Acetal can be detected by the standard metal detectable equipment that is typically used in quality inspection. This advancement in technology will reduce the risk of product containment, and help minimize the possibility of significant financial loss.
