Metal Detectable Additive & Polymers

What Are Metal Detectable Additives & Polymers?

Metal detectable plastic products are commonly used in food production environments, where consumables such as modular belting, cable ties and pens have the potential to contaminate the supply chain. If any part of a metal detectable plastic product becomes detached, it will be picked up by an industrial metal detector on the production line, preventing supply chain breakdown and expensive recalls.

Metal detectable additives are converted into an ultra-fine powder and extruded into a polymer masterbatch or mixed into bulk dough to produce metal detectable silicone rubbers. SCOPIC can supply either a metal detectable masterbatch, with either a universal carrier, a carrier tailored to your base material or a ready-dosed metal detectable compound, common compounds include metal detectable nylon and metal detectable TPU.

All of our masterbatches and compounds can be manufactured to the colour specifcation of your choice.

Traceability

Detection of foreign bodies by a metal detector is influenced by a variety of factors, including the following:

  • Aperture size of detector
  • Sensitivity setting
  • Type and orientation of ‘contaminant’
  • Type of product running through detector

Due to these criteria, it is difficult to confirm the absolute detection levels for metal detectable compounds and this should always be confirmed on the specific detection equipment under standard operating conditions.

Manufacturing & Testing

We have in-house extrusion and injection moulding capabilities to allow production of custom masterbatches and compounds, as well as moulded test pieces.

X-ray detectability can be checked on our Minebea X-ray Inspection System.

Mechanical testing can be performed on unfilled and detectable compounds to confirm the effect of the additives. Additionally we can offer tensile testing and impact testing on a variety of materials.

MFI (Melt Flow Index) levels of compounds can be confirmed on an extrusion plastometer.

UV exposure testing can be carried out if necessary on our Q-Lab UVC Accelerated Weathering Tester.
