New igus tribo polymers for safe food contact

Motion plastics specialist igus has now developed two
new optically and magnetically detectable materials for its plain and spherical
bearings. The iglidur FC180 and igumid FC meet the demand in the food industry
for machine components that offer media resistance, and are lubrication-free
and corrosion-free.

Compliant with FDA and EU10/2011 regulations, the new
materials allow quick identification of broken pieces in the event of damage to
a system, making them ideal for use in the food industry.

body detection by iglidur FC 180

The detection of foreign bodies plays a major role in
the production and packaging of food to ensure the perfect quality of products as
well as prevent contamination. Therefore, igus has now developed the
tribologically optimised plain bearing material iglidur FC 180 (FC = Food
Contact) specifically for food contact.

The new material is visually detectable by its blue
colour as well as by metal detectors due to the inclusion of appropriate,
food-compatible additives. In this way, broken pieces can be quickly detected
and removed in the event of damage to the system. As a result, the purity of
the product is secured and costly product recalls are prevented. The new
material complies with the specifications of the FDA and EU Regulation 10/2011
and can, therefore, be used in direct food contact.

“Its low moisture absorption and lubrication-free
properties are additional criteria that speak in favour of the optimum
suitability of the material in applications in the food technology, beverage
and packaging industries,” explains Lars Braun, Head of Packaging Industry
Management at igus.

detectability also for igubal spherical bearings

In the igubal spherical bearings range, the motion
plastics specialist now relies on a new detectable material. With the housing
material igumid FC in combination with iglidur FC180 as spherical ball
material, now igus – for the first time – has self-adjusting igubal bearings,
which are approved for direct food contact. The excellent detectability of the
materials was also confirmed by Sesotec GmbH, specialist for foreign body
detection and manufacturer of metal detectors for the food industry. Even the
smallest fragments of 0.0139 g (iglidur FC180) or 0.0157 g (igumid FC) could
still be identified on a conveyor belt when passing through the metal detector

The new vibration-dampening bearings are resistant to
corrosion and media due to their polymer base, allowing them to withstand cleaning
with water and other cleaning agents. As a result, equipment manufacturers and
operators in the food industry can now quickly and easily equip their machines
with a wide range of igus bearing solutions from Treotham while saving twice as
much. These plastic plain bearings don’t have to be serviced and are much more
cost-effective to buy than solutions consisting of sealed stainless steel
bearings with food-grade lubricants.
