Shanghai Zhubi Ronghui Trading Co., Ltd

We supply the HSD type Viscosity Index Improver (VII), a high-performance, star-shaped Hydrogenated Styrene-Isoprene (SIP) polymer. This "Made in China" product, available as a white foam or powder, is an essential lubricant additive for advanced formulations. It is comparable to grades like SV260, offering superior performance in viscosity management.

Specifically engineered as a viscosity modifier, our HSD VII provides a significant thickening effect combined with excellent shear stability. This robust shear resistance makes it the ideal choice for formulating high-grade, wide-span multi-grade oils, including premium gasoline engine oils and industrial lubricants.

Its advanced polymer structure ensures that the lubricant maintains optimal viscosity under varying temperatures and high-stress conditions, enhancing engine protection and efficiency. As a B2B supplier, we provide this key component to lubricant manufacturers seeking to create top-tier products with extended durability.
