Antioxidant Solutions for Thermal & Oxidative Stability
Quick Answer: Siya Polymer's antioxidant additives protect the polymer from thermal and oxidative degradation during extrusion, injection moulding and recycling, preventing yellowing, odour, and loss of mechanical properties.
Every time a polymer is melted — during extrusion, injection moulding, or repeated recycling — it is exposed to heat, shear and oxygen, all of which cause thermo-oxidative degradation. This shows up as yellowing or discolouration, a burnt or plasticky odour, loss of molecular weight, brittleness, and a drop in mechanical properties like impact and tensile strength. It's especially common in high-shear processing, multiple recycling passes, and light-coloured or natural (uncoloured) products where any yellowing is instantly visible. Left unmanaged, this problem quietly eats into your product's quality and shelf life. Siya Polymer & Speciality Chemicals helps processors protect the polymer from the inside with the right antioxidant package.
Siya Polymer's antioxidant additives (primary and secondary antioxidant combinations) protect the polymer against thermal and oxidative degradation during processing and in service.
