SI Group to Add China Location to Manufacture WESTON™ 705

Local team on-site at Chinaplas to meet with the industry while observing all necessary safety precautions 

Schenectady, N.Y. – April 14, 2021 – SI Group, a leading performance additives company, will begin producing its proprietary antioxidant WESTON™ 705 in China by May 2021. The additional sourcing point for this strategic antioxidant product will further increase security of supply for SI Group’s global customer base and will enable quicker expansion of the product in China and the rest of Asia Pacific region through compressed lead time and simplified logistics.

WESTON™ 705 is a modern liquid phosphite antioxidant that offers global regulatory compliance combined with a superior performance profile compared to the incumbent solutions. It represents an industrially proven drop-in substitute to TNPP in most of its applications and can be deployed in a broad range of Polyolefins and other Plastics and Elastomers that require stabilization. For example, to polyethylene producers, WESTON™ 705 brings much improved control of gels and plate-out in their resins relative to the common solid phosphite antioxidants. It also delivers significantly enhanced gas fading resistance. WESTON™ 705 can be beneficially utilized in variety of elastomers, such as SBR, BR, NBR, SBC and EPDM, to preserve their processability, color, and mechanical properties.

“This is a prime example of our investment in the Asia Pacific region,” said David Lu, SI Group’s VP & Managing Director – Asia Pacific. “We are committed to developing leading solutions that meet our customers’ needs with the global footprint to support reliable supply.”

SI Group’s local team is currently on-site at Chinaplas in Hall 15, Stall D39 to meet with industry partners and further explain the benefits of WESTON™ 705. The newly added manufacturing location in China will be equipped to produce both WESTON™ 705 and WESTON™ 705T in multiple packaging types based on customer needs.
