Magnetically detectable compounds based on PA 6 / PA 66
Polymers in the food industry - robust, light weight, flexible and versatile
These have many different advantages over metals: polymers are resistant, light weight and easier to shape and thus offer considerably more scope for design. When engineering plastics are used as a substitute for metals, however, it is not always possible to readily fulf il all the requirements. The nature of the materials means that aspects such as detectability and magnetisability are lacking.
Applications in the hygiene-sensitive food industry, however, require these properties in some cases. If fragments of plastics inadvertently make their way into the production process, as a result of damage, carelessness or defects, it is not only the resulting disruptions to production that pose problems. Much more serious is the danger that these fragments could end up in food and could pose a serious health risk if ingested. It is thus essential to ensure that these foreign bodies do not remain in the final product.
For safe enjoyment - detectable compounds minimise risk potential
ALAMID® D compounds are magnetically detectable. The basic polymer is modified with metal additives, allowing foreign bodies to be detected by the standard types of metal separator. This ensures that even the smallest particles of plastic can be reliably detected and removed from the production stream.
ALAMID® D compounds offer outstanding, individually adjustable alternative materials. These compounds guarantee maximum process safety, while leaving the characteristic properties of the basic polymers virtually unchanged. The products are supplied in conformity with the valid regulations governing polymers for food contact (e.g. Regulation 10/2011 (EU), FDA 21 CFR).
Think outside the box
In addition to the polyamides used for ALAMID® D to date, optimised, customised product solutions based on other engineering thermoplastics are also available. And, apart from reinforced grades, elastic variants (such as for cable tie applications), customised colours permitting clear visual differentiation from the end product, and conductive combinations are similarly possible.
