Ulsan, South Korea – Songwon has added a new stabiliser for polyols and polyurethanes to its product range. Songnox 5057 has applications in PU slabstock foams, elastomers and hot melt adhesives.
The product is a liquid butylated octylated aminic antioxidant. When applied in combination with hindered phenols, the company says it protects polyols against degradation during storage and transportation.
It also prevents discoloration in the centre of the foam during the manufacture of flexible PU foams.
‘Thanks to its low volatility and its liquid form, Songnox 5057 is suitable for numerous substrates and applications,’ explained Thomas Schmutz, leader for technical service & application development at the company.
‘In many industries, the quality standards required for foams are becoming more rigorous. Since it contains very little residual diphenylamine, it allows us to address specific customer needs in demanding polyurethane applications.’
The product is manufactured at the same facility in Ulsan where the company also makes aminic and phenolic antioxidants.
