Lanxess to introduce new products for tyre-makers at Tire Tech Expo 2017

LanxessLanxess Rhein Chemie Additives, a business unit of Germany-based specialty chemicals group Lanxess, is introducing a range of its latest solutions for tyre-makers all over the world at the upcoming Tire Technology Expo 2017 that will be held from February 14 to 16, 2017 in Hanover, Germany.

The company is presenting a comprehensive portfolio of eco-friendly Rhenodivtyre release agents, Rhenomarktyre marking paints, Rheno shape tyre curing bladders and Rhenogran aramid fibre masterbatches.

In order to enable tyre producers to apply very low quantities of inside lube onto the green tyre, Lanxess has developed new a new range of unfilled single-release inside lubes for cleaner tyre production: the Rhenodiv BP-337 and Rhenodiv BP-3091.

In combination with robotic spraying equipment, a precise coating procedure without contamination of tyre areas beside the inner liner is assured and the workplace is kept cleaner. As an extra benefit, Rhenodiv BP-337 is based on hydrogen-free cross linking chemistry.

There is an increasing demand for the absence of migrating silicones in the tyre molding process. This is especially the case if a clean, silicone-free tyre surface after vulcanisation is necessary. Rhein Chemie Additives is responding to this trend with two new single-release inside lubes:Rhenodiv BP-166 (low-filled, silicone-free) and Rhenodiv BP-9500 (unfilled, silicone-free).

Lanxess has also steadily upgraded operations at its different bladder production sites with automated processes to ensure quality aspects in accordance with customer requirements.

Rheno shape tyre curing bladders equipped with Rhenodiv permanent coatings enable tyre manufacturers to produce tyres without using an additional release agent. This is particularly important for the production of high-value tyres such as run-on-flat, sealant and noise-reduced tyres – wherever the absence of migrating silicone from traditional release agents is mandatory.

The company will also be showcasing the Rhenogran P91-40 that offers versatile mechanical reinforcement options for tyres. Itincorporates the highly resilient and very lightweight Twaron aramid short-fibre pulp evenly in the rubber compound under extreme mechanical, dynamic and thermal stresses. It also provides excellent reinforcement performance for tyre compounds.

In addition to polymers typically used in tyres such as NR, IR, BR and SBR, Rhenogran P91-40 is suitable for many other rubber grades including EPDM, CR, NBR and HNBR.
