In the world of polymer manufacturing, ensuring the longevity and performance of materials is paramount. Manufacturers constantly seek additives that can protect polymers from degradation caused by heat, light, and oxygen. One such critical additive is Diisodecyl Phenyl Phosphite, commonly known as PDDP. As a leading supplier of specialty chemicals, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-quality PDDP to meet these industry demands.

PDDP is a sophisticated organophosphite characterized by its high phosphorus content, which provides it with a superior ability to decompose hydroperoxides (ROOH) compared to many other phosphite antioxidants. This function is vital because hydroperoxides are key intermediates in the oxidative degradation of polymers, leading to loss of mechanical strength, discoloration, and reduced service life. By efficiently neutralizing these compounds, PDDP acts as an effective secondary antioxidant.

The benefits of using PDDP are extensive. It significantly improves the thermal stability of polymers, making them more resilient during high-temperature processing techniques like extrusion and molding. Furthermore, PDDP contributes to improved clarity and color retention, ensuring that the final products maintain their aesthetic appeal. This makes it particularly valuable for applications where visual quality is as important as functional performance.

PDDP is widely recognized for its synergistic effect when used in combination with primary antioxidants, such as hindered phenols, and UV absorbers. This synergistic action means that when combined, these additives provide a more robust stabilization package than each additive could achieve individually. This allows manufacturers to optimize their formulations, potentially reducing the overall additive load while achieving superior results.

Key applications for PDDP include its use in Polyvinyl Chloride (PVC), where it acts as an excellent secondary antioxidant and chelating agent, helping to maintain transparency and inhibit color change, especially when used with metal soap stabilizers. In Polyurethane (PU) systems, PDDP is utilized in films and adhesives to enhance resistance to oxidative stress. Its utility also extends to rubber, latex, rosin, and unsaturated resins, where it safeguards against environmental degradation.
