Leverkusen, Germany - Speciality chemicals group Lanxess has developed Nanoprene, a new high-performance rubber additive for tyres, which it claims can cut the wear of the tyre.
Lanxess said in a 14 Jan statement that the additive does not in any way impact on rolling resistance or wet grip â€œBoosting tyre service life without losing other key tread properties,â€
â€œThe wear properties of a tyre rubber are linked to its wet grip and rolling resistance through the 'magic triangle' of tyre technology,â€ said Proffesor Werner Obrecht, the developer of Nanoprene and a rubber expert at the Lanxess Technical Rubber Products business unit.
â€œTo put it simply, it is not possible to have everything at once, for example low fuel consumption, reliability on dry and wet roads and a tyre that lasts forever. If improvement is desired for one of these properties, this is not feasible without making concessions on the others,â€ he added.
According to Obrecht, Nanoprene reduces this conflict of objectives. The additive consists of particles of only around 50 nanometers made from polymerised styrene and butadiene -- traditional tyre rubber raw materials.
The difference with this product is the minimal size and surface functionality as a result of the production process used to make them.
According to Lanxess, the nanoparticles have a swell-resistant, highly cross-linked core with special anchor points on their surface, enabling the Nanoprene particles to be perfectly linked with silica and silanes, said the company.
