Why pounds ?为何要发展白炭黑胎面?
By applying silica instead of carbon black in tire pounds the following results can be achieved : 用白炭黑代替炭黑具有如下优越性能:
much lower rolling resistance of the tire 轮胎滚动损失降低很多
much better ice and snow performance 抗冰滑和抗雪滑行能优越很多
much better wet skid behaviour 抗湿滑性能改善很多
at similar tread wear patterns 具有相近的耐磨性
ABS-brake works only with silica on the wet road

History of silica technology
白炭黑技术发展简史
1974 Blue silica tire developped by Metzeler / Germany High loading of silica and BR, no S-SBR available, insufficient processing equipment and know how
1975 Metzler stopped production of blue tire
1980- several developments: silanes, rubbers,
1990 processing equipment and processing know how
1992 Patent on Green Tire of Michelin / France S-SBR, less silica and BR, improved processing equipment and procedures
2000 State of the art silica tire achieves up to 30 % improvement of physical properties but has remarkable processing deficiencies

Up to 35 % reduced rolling resistance with silica
Up to 5 % less fuel consumption per car
or approx. 2 billion litres of fuel savings per year in Germany alone
Green Tire Concept: Economic Benefit
绿色轮胎的概念:获得经济效益
使用白炭黑可使滚动阻力最多可降低35%
每辆轿车的耗油量最多可节省5%
仅在德国,每年可以节省20亿升的燃料
Green Tire Target for Economic Benefit
绿色轮胎的目标是获得经济效益
