Abstract: This article focuses on the effect of replacing SBR1723 with SBR152 in the application of ultra-
high performance tread formulations. The results showed that the physical properties of rubber compound in
the semi steel tire tread formula were significantly improved, including the constant tensile stress (50%, 100%,
300%), tensile strength, elongation at break, permanent deformation, tear strength and other indicators. In
terms of vulcanization performance, the Mooney viscosity of rubber compound after replacement decreased,
while the scorch time remained basically unchanged, which was conducive to improving the plasticizing
effect of rubber compound, thus enhancing the processing performance of tread rubber compound. In terms
of finished product performance, there were no significant changes in the strength, durability, and high-speed
performance of the test tires. However, from a cost perspective, this alternative solution helps to reduce the
production and operation costs of enterprises and has a positive impact on their profit margins.

晓星新材料拟建立印度帘线工厂
Xiaoxing New Materials plans to establish an Indian cord factory
近日，晓星新材料公司与印度马哈拉施特拉邦政府，签署谅解备忘录。
这家韩国企业，计划在当地建设一座轮胎帘线工厂。晓星新材料公司首席执行官成洛阳，与当地官员一同出
席签约仪式。
据了解，该项目总投资额，为 174 亿卢比（约合人民币 14.5 亿元）。为建设工厂，晓星新材料公司，计划收
购 70~100 英亩士地。目前，土地转让手续已经准备好，只需要最后签字完成。
数据显示，晓星新材料公司，占印度轮胎帘线市场份额的 56%。截至 2021 年，印度汽车拥有率全球最低，
每 1 000 人拥有 22 辆汽车。
自 2022 年起，该国汽车销量开始暴增，每年增长超过 20％。
2024 年，晓星新材料公司表示，要培育印度轮胎帘线生产基地。
