一、国内外合成橡胶在轮胎中的应用动态据有关资料介绍,日本生产的轮胎产品主要橡胶耗用比例约是:天然胶占45%、丁苯胶占30%、顺丁胶占10%,美国丁苯胶与顺丁胶在轮胎中应用比例也是约3∶1,俄罗斯轮胎产品中丁苯胶应用比例最大。国内轮胎工业的丁苯胶使用比例相对较低,与国外有
First, the application of synthetic rubber in the tire at home and abroad According to the relevant information, the main rubber consumption ratio of the tire products produced in Japan is about 45% of natural rubber, 30% of SBR, 10% of butadiene rubber, US SBR and butadiene rubber in the tire application ratio is about 3: 1, the Russian tire products, the largest proportion of styrene-butadiene rubber applications. Domestic tire industry, the use of styrene-butadiene rubber is relatively low, with foreign countries
