Tris(nonylphenyl) phosphite
Tris(nonylphenyl) phosphite (CAS 26523-78-4) is a versatile chemical compound with the linear formula (C9H19C6H4O)3P and a molecular weight of 689.00 g/mol. Primarily employed as a heat stabiliser, it plays a crucial role in enhancing the thermal stability and longevity of various polymeric materials. Its phosphite structure contributes to its effectiveness in preventing degradation during processing and end-use applications.
Polymer Heat Stabilisation
Acts as an effective secondary antioxidant and heat stabiliser for a wide range of polymers, including polyolefins, PVC, and elastomers. It protects materials from thermal degradation during high-temperature processing and service life.
Antioxidant Additive
Functions as a secondary antioxidant, synergising with primary antioxidants to provide comprehensive protection against oxidative and thermal breakdown. This extends the useful life of plastic components and finished goods.
Processing Aid for Plastics
Improves the processability of polymers by reducing viscosity and preventing chain scission at elevated temperatures. This leads to more consistent production and improved surface finish of moulded or extruded articles.
