SI Group and Shengxiao Group to boost biphenol production in China

SI Group and Shengxiao Group, a global leader in liquid crystal polymer (LCP) monomers and specialty chemicals, announced the formation of a joint venture to accelerate additional capacity of Biphenol in China.

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.

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.

“We are pleased to partner with SI Group to form Shengnova Advanced Materials to supply Biphenol to customers in Asia,” said Guo Xiaozhong, Chairman of Shengxiao Group. “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.”

“This joint venture advances SI Group’s growth strategy and strengthens our ability to serve customers in key markets around the world,” said David Bradley, President and CEO of SI Group. “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.”
