Aromatic oils eliminated from Aeolus TBR production
China’s Aeolus Tyre reports the phasing out of aromatic oil in the production of its truck and bus radial tyres. The Henan province-based manufacturer says that as of May 2011 it has ceased using the rubber accelerator NOBS, curing agent DTDM and antioxidants in the manufacture of TBR tyres intended for the domestic market; tyres intended for export markets have been produced using environmentally-friendly oils for more than two years now. In announcing its total changeover to low-PAH (polycyclic aromatic hydrocarbon) substances, Aeolus Tyre states it the first 100 per cent environmentally-friendly TBR tyre manufacturer in China.
The tyre maker’s decision to eliminate aromatic oils during the production of its TBR tyres was taken in the absence of any domestic industry standard. Aeolus says it aims achieve environmental friendliness in both the manufacturing process and in the tyres themselves; the company says it has worked to lower the rolling resistance of its TBR tyres and currently utilises a high proportion of silica in place of carbon black plus a self-developed technology to achieve a well-dispersed mixture of nano-silicate filler.
