About Wynca

Zhejiang Xinan Chemical Industrial Group Co., Ltd. (known as Wynca Group) was founded in 1965, and listed in Shanghai Stock in Sept. 2001.

 

Wynca is primarily engaged in three core businesses: crop protection, silicon-based new materials and phosphorus-based new materials.The company has established a comprehensive silicone industry chain, encompassing the smelting of silicon metal, synthesis of monomers, and the production of silicone downstream products. This has led to the creation of four major product series: silicone rubber, silicone oil, silicone resin and silane coupling agents. All of those have contributed to the company’s superiority of whole industrial chain in the industry.

 

Wynca is dedicated to a global strategy, pursuing development that is high-end, intelligent, and environmentally sustainable. Its products are distributed across numerous countries and regions worldwide. The company has established subsidiaries in North America, South America, Africa, Europe, and Malaysia, and and has established strategic partnerships with Momentive and Evonik. These alliances have played a pivotal role in the sustained enhancement of Wynca's global brand popularity and market shares.
