While developing a low rolling resistance tire compound, the YH-75 silane coupling agent and specialty Carbon Black N330 supplied by Yuanhe Hengsheng showed outstanding performance in preliminary tests—especially in wet grip and durability. Beyond providing samples, they also shared multiple sets of application data, which greatly accelerated our R&D process.

Since 2023, we have adopted Carbon Black N550 from Yuanhe Hengsheng. Not only is the product cost-effective, but their technical team also provided tailored optimization advice based on our production conditions, improving our mixing efficiency by approximately 8%. Throughout our cooperation, product quality has been stable and deliveries always on time, providing strong support for our cost reduction and efficiency improvement goals.

We have been using YH-69 silane coupling agent from Yuanhe Hengsheng for three years. The product offers excellent batch consistency and compatibility, significantly enhancing the anti-aging performance of our tire compounds. Their technical team is highly responsive and has assisted us multiple times with on-site process optimization. They are a reliable strategic supplier.
