SI Group to produce antioxidant in China

SI Group, a leading performance additives company, is set to start production of its proprietary antioxidant WESTON 705 in China by May 2021. With the additional capacity, 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 stabilisation. 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 utilised in variety of elastomers, such as SBR, BR, NBR, SBC and EPDM, to preserve their processability, colour, 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.
