SONGWON starts production of SONGNOX 5650 at plant in India

To ensure the availability of SONGNOX 5650 worldwide, SONGWON has started to manufacture the product at its Panoli plant in Gujarat, India.

SONGNOX 5650 is a high molecular weight, multifunctional phenolic antioxidant primarily used as a post-polymerization process stabilizer for unsaturated elastomers. Placing strong emphasis on reliable supply, SONGWON began manufacture of SONGNOX 5650 in Panoli last September. This additional, in-house production capacity enables SONGWON to ensure reliable supply of SONGNOX 5650 worldwide. The Panoli site was acquired from Sequent in 2014.

“In the last three years, SONGWON has continuously invested in the Panoli site to develop it into a hub for specialty chemicals, including SONGNOX® 5650,” said Elena Scaltritti, Leader Polymer Stabilizers.

Phenolic antioxidants are highly effective, non-discoloring stabilizers for organic substrates that are prone to oxidation, including plastics, synthetic fibers, elastomers and waxes. They act as free radical scavengers, and are mainly used to protect the finished product.

“Thanks to its unique properties, SONGNOX 5650 can match the performance of stabilizers that have to be used in much larger amounts,” said Thomas Schmutz, Leader Technical Service & Application Development. “And as a result of its very low volatility, there is virtually no product loss during polymer processing, drying or storage. These features make it highly cost effective.”

This non-staining antioxidant is suitable for a variety of elastomers, including polybutadiene, polyisoprene, emulsion styrene butadiene, nitrile rubber, carboxylated styrene-butadiene-rubber latex and styrene copolymers. It can also be used in hot melt, solvent-based adhesives as well as natural and synthetic tackifier resins.

SONGNOX 5650 has broad food contact approval, making it especially suitable for pressure sensitive adhesives. Besides high protection against oxidation, it provides good long term thermal stability.
