Songwon (Songwon) has developed and launched a new antioxidant, Songnox 5057. Songnox 5057 complements Songwon's extensive line of amino, phenolic, phosphite and thioester antioxidants. This new liquid butyloctyl ammoniated antioxidant is suitable for a wide range of substrates, including polyols. It is designed for use in flexible polyurethane block foams, elastomers and hot melt adhesives. Foams are widely used in many different industries such as furniture, bedding, auto parts and sporting goods.

Songnox 5057 is used in combination with hindered phenols such as Songnox 1135 or Songnox 1076 to protect polyols from degradation during storage and transportation. In addition, this combination prevents charring, i.e., discoloration in the center of the foam, during the manufacture of the polyurethane soft foam.

Songnox 5057 is manufactured at Songwon's world-class facility in Ulsan, South Korea. As other industry-standard amino acids and phenolic (Songnox 1135) antioxidants are already produced there, the new product helps to further add economic value through increased production efficiency and scale.

" Due to its low volatility and liquid form, Songnox 5057 is suitable for a wide range of substrates and applications. In many industries, the quality standards required for foams have become more stringent. Since Songnox 5057 contains almost no residual diphenylamine, we can meet the specific needs of our customers in demanding polyurethane applications, "says Thomas Schmutz, who is responsible for technical service and application development. Elena Scaltritti, Polymer Stabilizers Leader of the

Business Unit, said: "Songwon's focus on, and continued investment in, critical and cutting-edge solutions that meet today's high standards once again underscores our long-term commitment to the plastics additives industry. In addition to polyolefin, the additional in-house production capacity enables Songwon to successfully expand its production capacity by developing additives for other products."
