最近,有新闻称,世界最大的轮胎供应商普利斯通将从银胶菊和俄罗斯蒲公英中提取橡胶,并有可能在2015年就投入商业生产。怎么,蒲公英里面也会有橡胶?目前几乎所有的天然橡胶都是从一种原产南美的橡胶树上采集的。这种天然橡胶有很独特的性质,至今也不能被合成橡胶所替代。实际上,天然橡胶在橡胶供应中所占的比例,已经从上世纪七八十年代的百分之三十逐渐上升到现在的超过百分之四十,年产量已经超过一千万吨。它广泛应用到超过四万种产品中,成为人们日常生活不可或缺的必需品。不过,天然橡胶一直存在着供应危机。
Recently, there is news that Bridgestone, the world’s largest tire supplier, will extract rubber from gutta-percha and Russian dandelion, and it may be put into commercial production in 2015. How can there be rubber in dandelion? Almost all natural rubber is currently collected from a rubber tree native to South America. This natural rubber has very unique properties and it has not been replaced by synthetic rubber so far. In fact, the proportion of natural rubber in the rubber supply has gradually increased from 30% in the 1970s to the current more than 40%, and the annual output has exceeded 10 million tons. It has been widely used in more than 40,000 kinds of products and has become an indispensable necessities for people’s daily life. However, natural rubber has always had a supply crisis.
