SI Group and Shengxiao Group Establish Joint Venture to Accelerate Biphenol Capacity Expansion in China

On June 25, 2026, SI Group and Shengxiao Group announced the formation of a joint venture named Shengnova Advanced Materials, aimed at enhancing the supply of Biphenol in China. While the financial details of the deal remain undisclosed, this collaboration seeks to leverage Shengxiao Group's manufacturing capabilities alongside SI Group's advanced technology to meet the increasing demand for Biphenol across various sectors, including electronics, automotive, and medical.

Shengnova Advanced Materials will be based in Sichuan, China, and will combine the established manufacturing assets of Shengxiao Group with SI Group's proprietary expertise in Biphenol production. Biphenol is a critical monomer utilized in the production of liquid crystal polymers (LCP), polyphenylenesulfone (PPSU), and other high-performance materials. This joint venture is strategically positioned to bolster local supply chains and reduce reliance on imports, addressing a growing need for these materials in the Asia Pacific region.

The partnership reflects a broader trend in the specialty chemicals sector, where localized production capabilities are becoming increasingly essential. As industries such as electronics and automotive continue to evolve, there is a heightened demand for high-performance materials that can meet stringent specifications. By establishing Shengnova Advanced Materials, both SI Group and Shengxiao Group aim to capitalize on this demand, ensuring they can deliver quality products to their customers in a timely and efficient manner.

The joint venture is also indicative of SI Group's growth strategy, which focuses on expanding its operational footprint to better serve global customers. David Bradley, President and CEO of SI Group, emphasized that the formation of Shengnova Advanced Materials not only enhances the company's ability to supply Biphenol competitively in Asia but also reinforces the security of supply through a diversified production approach. This strategy aligns with the increasing emphasis on supply chain resilience in the face of global market fluctuations.

Overall, the establishment of Shengnova Advanced Materials highlights the ongoing evolution within the specialty chemicals sector, particularly in response to rising demand for advanced materials in key industries. As companies like SI Group and Shengxiao Group invest in local production capabilities, the implications for market dynamics could be significant, potentially leading to increased competition and innovation in the Biphenol supply chain. This joint venture marks a strategic move that could reshape the landscape of high-performance materials in the Asia Pacific region.
