Two new FDA compliant metal detectable materials have been introduced by Emco Industrial Plastics. The first is a metal detectable grade of Acetal. Acetal (POM) polymer has superb inherent mechanical properties in respect of dimensional stability, strength, stiffness and low wear characteristics. Acetal is suitable for replacing metal parts that are currently fabricated. This new metal detectable grade is color coded in a bright blue tint, it is FDA compliant and remains easy to machine and is dimensionally stable. The product is easily sensed by standard metal detectors and is available in rod form 1/8” to 8” in diameter and sheet thickness from 3/8” to 8”. Some typical applications are conveyor belt links or pins, food processing fabricated parts, scrapers, spatulas, and most threaded or turned components.
The second material is a FDA compliant, metal detectable UHMW Polyethylene that has been designed primarily for the food processing industry. Since metal detectable UHMW has high impact strength and has no moisture absorption properties, it fills the food industries need for a reliable, traceable and cost-effective plastic for machined parts. It is available in rod form 1/8” to 8” in diameter and sheet thickness from 3/8” to 8”. Typical applications are wear-strips, pillow blocks, guides, scraper blades and mixer components.
