Ultra detectable food grade acetal

TECAFORM AH UD blue is a revolutionary new food grade plastic that is an ultra detectable POM-C (acetal copolymer), designed specifically for food contact applications in the food industry. At the same time, it retains its typical properties such as good sliding wear behaviour and mechanical balance. Food safety is extremely important in the food industry, as companies try to assure their products only come in contact with FDA and EU 10/2011 compliant materials in the food zone. High speed food production lines detect particulate matter in the food product in one of three ways; Using optical scanners that have the ability to readily detect blue materials, metal detection equipment, or x-ray equipment. All three methods are designed to help keep food safe from unwanted particulates. TECAFORM AH UD blue is the first multi-detectable plastic that will show up regardless of the scanning method being used.
