Metal detectable engineering thermoplastics for food processing machine builders

06 December 2010

Quadrant has introduced a range of metal detectable (MD) engineering thermoplastics to support the food processing industry’s need for reliable, traceable, and cost-effective machine parts, including a choice of polyethylene (PE), polyoxymethylene (POM), and polyamide (PA6) based food contact approved MD engineering materials.

The food processing industry requires plastics equipment parts that will provide the high level resistance to wear and tear, and the cleanliness necessary for today’s fast line speeds. At the same time parts must provide the reassurance of easy detection should fragments or particles break off and fall into the foodstuff during processing. Metal detection is the most economical, dependable and therefore common form of monitoring for potential contamination.

Quadrant’s set of three MD modified plastics comprises TIVAR MD based on ultra-high molecular weight polyethylene (PE-UHMW); Acetron MD based on POM; and Nylatron MD based on PA6. Acetron MD and Nylatron MD are available in a blue colour to aid visual as well as MD detectability; X-ray detection is also possible. TIVAR MD is available in grey colour.
 
All materials deliver the necessary MD level for particles as small as 3mm x 3mm x 3mm. In addition to food compliance (according to FDA and EU Directive 2002/72 EC standards), the individual materials offer the advantages of  good impact resistance, high wear resistance and good machining properties.

Stock shapes of the three products will be offered as extruded rods or plates in various sizes.
