Sustarin® C XDT was the first X-Ray detectable extruded sheet and rod offered for machined parts and components in the food processing industry. It is FDA compliant and meets the federal requirements for food contact.

With new regulations in place, the FDA now mandates that all food processors have comprehensive preventative controls and safety programs in place. Repeated handling, cleaning, and normal wear and tear of plastic component parts on processing machinery increases the risk of a fragment breaking off and contaminating the product, especially with the ongoing pressure to increase production line speeds. Quality checks are performed at process control points typically with either metal or X-ray detection systems. In many cases, X-ray systems are required or preferred due to the fact that the system can effectively detect contamination post-packaging.

Sustarin® C XDT has been proven to be detected in a particle as mall as a 3mm cube on production lines running as fast as 250 feet-per-minute.

Together with Polystone® M XDT UHMW-PE and SustaPEEK® XDT there are now three of the most commonly used engineering plastics in the food processing industry in these special X-ray detectable grades.
