SI Group and Shengxiao Group establish JV to expand Biphenol capacity in China
SI Group, a leading global manufacturer of performance additives, process solutions, and chemical intermediates, and Shengxiao Group, a global leader in liquid crystal polymer (LCP) monomers and specialty chemicals, have formed joint venture – Shengnova Advanced Materials – to accelerate additional capacity of Biphenol in China.

The Joint Venture agreement signing ceremony.
“As a leading supplier of monomers for liquid crystal polymers (LCP), Biphenol is a key component of our portfolio. Our customers appreciate in-region supply and bringing SI Group’s Biphenol expertise to China will benefit the growing end markets in the region,” said Guo Xiaozhong, Chairman of Shengxiao Group.
Based in Sichuan, China, Shengnova Advanced Materials combines Shengxiao Group’s established Biphenol manufacturing asset and regional market access with SI Group’s proprietary technology and global Biphenol expertise. By bringing these capabilities together, the joint venture is designed to increase local supply of this unique molecule.
“Through the formation of Shengnova Advanced Materials, we are expanding our ability to competitively supply Biphenol to customers in Asia while continuing production at our Newport, Tennessee facility. This positions SI Group to better serve global customers, support growing regional demand, and reinforce security of supply through a multi-region production footprint,” added David Bradley, President and CEO of SI Group.
Biphenol is an important monomer used in liquid crystal polymers (LCP), polyphenylenesulfone (PPSU), and other applications. The venture positions both partners to support growing demand across sectors including electronics, automotive, and medical, where high-performance materials are essential to next-generation applications.
