Green thumb rules in the tyre industry Fluctuating supply and prices of latex

(TDAE) oil, used as a raw material for tyres; and is designed especially for high performance summer tyres, according to Arlanxeo, a joint venture of German speciality firm Lanxess and state-owned petrochemical company Saudi Aramco. The other product, Buna FX 5000, a high vinyl SSBR, features Arlanxeo´s second generation functionalisation technology. It is also designed to interact with silica fillers to boost fuel economy. This product contains 7 phr TDAE oil extension, which offers the compounder the chance to optimise rolling resistance through the reduction of filler loadings, Arlanxeo states.

rubber and a growing demand for more eco-friendly technologies are antecedent to the development of a flourishing green tyre sector, says Angelica Buan.


lobal demand for both synthetic rubber and natural rubber is set to grow to almost 40 million tonnes by 2020, according to Singapore-headquartered trade organisation International Rubber Study Group. This projection may encounter a few hiccups as 2017 unfolds since, currently, season-related latex rubber shortage, especially from major Asian producers, is tightening rubber supply, the Association of Natural Rubber Producing Countries (ANRPC) cited in its report published in January. It mentioned that the global supply of natural rubber will be short of demand by 350,000 tonnes during the year. Likewise, synthetic rubber materials are more expensive this year, stated ANRPC, in anticipation of higher feedstock prices, driven by a call from the Organisation of Petroleum Exporting Countries (OPEC) to cut oil output by 1.2 million barrels/day for the first six months of 2017. The non-OPEC countries, led by Russia and Mexico, also pitched in by staving off an additional 558,000 barrels/ day in oil production. Apart from the volatile prices, sustainability of tyres is becoming relevant at this time that pollution, climate change and waste management are critical issues.

Arlanxeo’s new Buna SSBRs are designed to interact with silica fillers for low resistance and fuel efficient tyres

Turning over a new leaf with green tyres reen tyre’s eco-friendly edge is having low rolling resistance – the friction between the tyres and the surface. On the contrary, traditional rubber tyres have higher rolling resistance, which require more energy to overcome the friction and so resulting in more pollutants being released. In the green tyre segment, Netherlandsheadquartered synthetic rubber company, Arlanxeo, has recently introduced new solution styrene butadiene rubbers (SSBR), Buna FX 3234A-2 and Buna FX 5000, that feature first and second generation functionalisation technologies, respectively. Buna FX 3234A-2, a high styrene SSBR is designed to interact with silica fillers in order to reduce rolling resistance in passenger tyre treads. The product contains 37.5 phr of treated distillate aromatic extract

Meanwhile, parent company Lanxess also offers a range of eco-friendly tyre solutions through its additives business unit, Rhein Chemie Additives. The products were showcased at the Tire Technology Expo held in Hannover, Germany, recently. Rhein Chemie Additives has developed a new range of Rhenodiv range of unfilled single-release inside lubes for cleaner tyre production. First to mention are the Rhenodiv BP-337 and Rhenodiv BP-3091 that enable tyre producers to apply very low quantities of inside lube onto the green tyre. The company furthered that in combination with robotic spraying equipment, this allows for a precise coating procedure to be carried out with the assurance that no area of the tyre outside the inner liner will be contaminated. An additional benefit is that Rhenodiv BP-337 is based on hydrogen-free crosslinking chemistry.
