Tris(nonylphenyl) phosphite (TNPP)
Additive
TNPP is a secondary antioxidant widely used in polymer stabilization, especially in PVC and polyolefins. It acts as a peroxide decomposer, protecting the material against thermal and oxidative degradation during processing.
Its use helps maintain the material’s properties, improve color stability, and extend the service life of the final product.
