Tailor made Silica/Silane-Systems

Precipitated Silica – Morphology Control

Precipitated silica, especially in combination with bifunctional organosilanes, is one of the most important active filler, filler system respectively, that is used in the rubber industry and especially in passenger car tire tread compounds. Despite the fact that there are already many different silica having a broad range of different specific surface areas, the variety of cluster sizes in the nanometer range is rather low in contrast to the broad range of available carbon black structure variations. more...

Crack Propagation of Vulcanized Rubber

Ozone-Resistivity of Isoprene Rubber mixed with a Wax as an Antiozonant at below Freezing

Effect of wax on the ozone resistance of vulcanized natural rubber (NR) and vulcanized isoprene rubber (IR) was investigated by observing crack propagation of the vulcanized rubbers at 40°C and -30°C under 50 pphm ozone atmosphere. The ozone exposure test for the vulcanized rubbers was performed, after the wax bloomed at 40°C under a strain of 0.2. more...

Self-sealing tires make spare wheels redundant .(Bildquelle: Lanxess)

Arlanxeo at Tire Technolgy Expo 2018

Rubber Compound for self-sealing Tires

Arlanxeo has developed a rubber compound that can be used in the future to seal tires. This solution for so-called self-sealing tires replaces the spare wheel and also presents an alternative to a repair kit or run-flat tire. An appropriate rubber compound, which is applied on the interior of the vehicle tire, enables holes occurring in the tire to be automatically sealed, so the driver can continue driving. Arlanxeo is presenting the development at Tire Technolgy Expo 2018, Booth 4014. more...
