Magnethane Usage Guidance

Magnethane Testing

Magnethane is intended to be a last alert detection option. Although magnetic traps have proven effective in removing abraded pieces, we do not recommend magnetic retrieval as the primary method of protection. The removal of small pieces from the food stream should be done mechanically as a result of the detection signal generated from Magnethane products. By enabling metal detectors to see the tramp material, customers may physically deal with it. Our products are offered from the detection platform, not as an extraction program.

It is not possible to guarantee 100% detection rates. Magnetic detection equipment varies in sensitivity and operational parameters. It is advisable for customers to test detectability and make necessary adjustments with their own systems prior to full integration.

Clients reworking tpu should ensure work is carried out in a well ventilated area using trained staff and complies with all regulatory requirements.

Food contact

It is assumed that Magnethane will be in contact with foodstuffs for brief contact repeat use in a temperature range between -17°C to +80°C.
