Introduction
The tris nonylphenyl phosphite (TNPP) market is expanding steadily as industries rely on high-performance stabilizers to improve polymer durability and processing efficiency. According to Stratview Research, the tris nonylphenyl phosphite market is projected to reach US$459.7 million by 2028, growing at a CAGR of 5.8%. This growth is driven by increasing demand for plastics across packaging, automotive, construction, and industrial applications.

Key Features
TNPP is a highly effective secondary antioxidant widely used to enhance thermal stability and prevent polymer degradation during high-temperature processing. Its strong hydrolytic stability, color protection capability, and compatibility with various polymer systems make it one of the most preferred phosphite stabilizers. TNPP also improves melt flow, helping manufacturers achieve smoother and more efficient processing.
