Polyurethanes (PUs) are valued for their versatility and performance, finding applications in everything from coatings and adhesives to foams and elastomers. However, a common challenge in PU formulations is yellowing, often caused by exposure to light and heat, particularly nitrogen oxides (NOx). To combat this, formulators rely on effective antioxidants, and phosphite esters like Poly(dipropyleneglycol)phenyl phosphite (CAS 80584-86-7) are indispensable. As a specialized manufacturer and supplier, we provide this advanced solution to enhance PU durability.

Poly(dipropyleneglycol)phenyl phosphite serves as a potent secondary antioxidant. Its unique molecular structure, characterized by high molecular weight and high phosphorus content, makes it particularly effective in decomposing hydroperoxides that initiate degradation pathways. Crucially for PU applications, it exhibits a significant inhibitory effect against phenol yellowing and NOx yellowing. This property is vital for maintaining the aesthetic appeal and functional integrity of polyurethane products over time.

When you consider purchasing this essential additive, here’s what makes it a valuable component for your polyurethane systems:

  • Anti-Yellowing Performance: It effectively prevents the yellowing that can occur in polyurethanes due to environmental factors, ensuring products maintain their original color.
  • Improved Thermal Stability: Beyond color protection, it enhances the overall thermal stability of polyurethanes, crucial for applications involving elevated temperatures during processing or use.
  • Synergistic Effects: It works harmoniously with other stabilizers, such as UV absorbers and hindered amine light stabilizers (HALS), to create a comprehensive protection system for your PU formulations.
  • Liquid Form for Easy Handling: The liquid nature of Poly(dipropyleneglycol)phenyl phosphite facilitates straightforward incorporation into various polyurethane systems, from coatings to flexible foams.
