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-polymerisation process stabiliser 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, according to Elena Scaltritti, Leader Polymer Stabilisers.
Phenolic antioxidants are highly effective, non-discolouring stabilisers for organic substrates that are prone to oxidation, including plastics, synthetic fibres, elastomers and waxes. They act as free radical scavengers, and are mainly used to protect the finished product.
With its unique properties, SONGNOX® 5650 can match the performance of stabilisers that have to be used in much larger amounts and as a result of its very low volatility, there is virtually no product loss during polymer processing, drying or storage making it highly cost effective, added Thomas Schmutz, Leader Technical Service & Application Development.
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.
