Abstract
A conveyer module, small fragments of which are detectable by X-ray and magnetic sensors, is formed from a compounded mixture of a thermoplastic polymer and a ferrous metal powder. The thermoplastic polymer comprises a polyketone constituting less than 85% by weight of the mixture. The ferrous metal powder is a 400 series stainless steel constituting between 16% and 20% by weight of the mixture.

A conveyor module, comprising:
- a compounded mixture of a thermoplastic polymer and a ferrous metal;
- wherein the thermoplastic polymer is a polyketone, the thermoplastic polymer constituting less than 85% by weight of the mixture;
- and,
- wherein the ferrous metal is a 400 series stainless steel powder, the ferrous metal constituting between 16% and 20% by weight of the mixture.
A method of making a conveyer module, small fragments of which are detectable by X-ray and magnetic sensors, the conveyer module being formed from a polyketone resin, the method comprising compounding a 400 series stainless steel into the polyketone resin prior to formation of the conveyer module.
