China’s high-performance rare-earth rubber faces a commercial test as manufacturers seek to expand its use in electric vehicle (EV) and heavy-duty tyres, with market data suggesting it commands a higher price than conventional synthetic rubber.
Rare-earth cis-butadiene rubber grade ND9106 was quoted at 22,500 yuan (US$3,400) per tonne in China during the week from October 26 to November 1, compared with 16,660 yuan per tonne for conventional BR9000 in Shandong province, according to market data published by the China Rubber Industry Association on November 2.
For tyre manufacturers, rare-earth rubber offers better wear resistance, greater strength and lower rolling resistance. The expansion of domestic production could help make the material more widely available.
