LANXESS will present its new high-performance additives for the tire industry at the Tire Technology Expo 2026.

The solutions help tire manufacturers to stabilize and improve the safety and material efficiency of their processes, reduce their ecological footprint, and enhance the efficiency of modern tires.

Sustainable alternative to 6PPD: Vulkanox 4060

As there are stricter regulatory requirements for the antioxidant 6PPD in the US and Europe, LANXESS developed Vulkanox 4060 (N,N'-dicyclohexyl-1,4-phenylenediamine, CCPD) as an alternative with an optimized environmental profile.

In tire compounds and finished tires, laboratory and application tests have demonstrated that the product provides comparable protection against oxidative aging.

LANXESS is preparing to register the product in accordance with the European REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulation for volumes exceeding 1,000 tons. Commercial production is scheduled to begin in the middle of the year.

Aflux SD: Efficient processing agent for silica dispersion

Aflux SD is a processing agent for silica that improves the flow behavior of compounds and the dispersion of fillers, especially when used with functionalized polymers. This additive is made from sustainable raw materials, is free of Substances of Very High Concern (SVHC), and significantly improves silica dispersion.

Among other things, this reduces the Payne effect, i.e., the rolling resistance of tires, their wear resistance, and wet grip are improved.

Regulation as a driver of innovation

Talc is used in the rubber industry as both a release agent and a filler. However, regulatory pressure on talc is increasing. LANXESS now offers the entire Rhenogran and Rhenoslab portfolio talc-free.

Cohedur RA is a safe alternative to resorcinol in coupling agent systems for textiles or steel cord. It contains no resorcinol, disperses easily, and prevents the blooming effects that typically occur with resorcinol-containing products.

Solutions for the production process

Rhenodiv BO-3900 Pearls Cool is a mineral-free, cold-water-dispersible batch-off release agent that significantly reduces deposits on plant surfaces. Thanks to its pearl form, the product can be dosed reproducibly and processed completely dust-free. Additionally, Pearls Cool impresses with its sustainable, resource-saving formulation.

The filler-free interior spray solution Rhenodiv BP-338 ensures that the vulcanized tire can be cleanly and without defects removed from the bladder after vulcanization. Although the product is not chemically reactive, it achieves the release effect of reactive systems. It requires significantly less material consumption than conventional solutions, and unlike traditional reactive systems, it does not release hydrogen during processing.
