According to EU Regulation 2024/3190, components with product contact may no longer use parts that contain the endocrine disruptor bisphenol-A from July 2026. Many designers are already looking for alternatives. Igus presented a solution at the Hannover Messe (Germany).

EU Regulation 2024/3190 is forcing manufacturers of machinery for the food industry to rethink. From July 2026, components with product contact may no longer use parts that contain the hormonally active plastic component bisphenol-A. The ban applies to all machines that are newly launched on the market. For existing product lines, the deadline is January 2028 and many designers are already looking for alternatives. At Hannover Messe 2026, Igus will be presenting the bisphenol-free plain bearing material Iglidur A351, which design engineers can switch to without any technical losses or additional adjustments.

With Iglidur A351, designers can continue to work in compliance with standards in the future. This is because the material is not only FDA-compliant, but also free from bisphenol-A and bisphenol-S.

Iglidur A351 can be used to manufacture sliding bearings for conveyor systems, gear wheels for packaging machines and components with direct product contact such as guides or spacers in filling and packaging systems. Igus produces the material in several manufacturing forms: as plastic granulate for injection molding, as semi-finished products for CNC machining and as filament for 3D printing. "Designers will also be able to work with Iglidur A351 in accordance with standards in the future. This is because the material is not only FDA-compliant, but also free from bisphenol-A and bisphenol-S," explains Lars Butenschön, Head of the Iglidur Plain Bearings business unit at Igus. "We want to make the transition easier for design engineers. Many have told us that the new EU Regulation 2024/3190 is causing major challenges in the procurement of suitable components."

High Stability With Low Weight

The material has a density of around 88.6 lb/ft³. This gives it high stability and low weight compared to metal solutions. At the same time, the material achieves a compressive strength of around 78 MPa, meaning that components can work reliably even under higher surface pressures. Another advantage is the low moisture absorption of around 0.6 percent. This ensures dimensional accuracy and functional reliability even in damp production environments. Furthermore, Iglidur A351 is designed for continuous temperatures between 148°F and 356°F. The material can therefore withstand high process temperatures in the food industry and intensive cleaning cycles.

Self-Lubricating Effect for More Economical Machines

As part of the Iglidur product family, Iglidur A351 also relies on integrated solid lubricants. Unlike metal bearings, they enable hygienic dry running without external lubricants. "This self-lubricating effect significantly reduces maintenance work, making machines both more economical and more reliable," says Lars Butenschön. Another characteristic is the blue color of the material. In the food industry, it increases detectability via optical systems and therefore product safety.
