In the competitive landscape of polymer manufacturing, maximizing product lifespan and performance is crucial. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of advanced additives designed to meet these challenges, with our Phosphite Antioxidant 4500 being a standout solution. This additive leverages the power of synergistic effects to deliver superior protection and economic benefits.

Antioxidants are essential for preventing polymer degradation caused by oxidation. While primary antioxidants, such as hindered phenols, act as radical scavengers, secondary antioxidants like phosphites play a complementary role. Phosphites are particularly effective at decomposing hydroperoxides, which are key intermediates in the oxidation chain reaction. By breaking down these peroxides, phosphites prevent further oxidative damage to the polymer structure.

The true strength of Phosphite Antioxidant 4500 lies in its ability to work in harmony with primary antioxidants. This synergistic effect with primary antioxidants means that when used together, the overall antioxidant protection is significantly enhanced compared to using either type of antioxidant alone. This elevated performance allows for lower overall additive loadings, contributing to significant cost reduction in polymer additives without compromising the final product's quality. Manufacturers can achieve superior protection more efficiently and cost-effectively.

This antioxidant excels in providing excellent heat resistance for thermoplastics and improving hydrolysis resistance. These properties are vital for polymers that are processed at high temperatures or are exposed to humid environments. By mitigating degradation pathways related to heat and moisture, Phosphite Antioxidant 4500 helps maintain the mechanical integrity and appearance of the final products, thereby improving polymer stability.

Furthermore, the additive plays a critical role in preserving the visual appeal of polymers, contributing to excellent color retention in plastics. This is particularly important in applications where aesthetics are a key selling point. Whether used in PVC formulations or other plastic and rubber applications, the ability of Phosphite Antioxidant 4500 to prevent discoloration ensures that products retain their desired look throughout their lifecycle.

At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to providing innovative solutions that empower our customers. Phosphite Antioxidant 4500 is a testament to this commitment, offering a powerful combination of performance enhancement and economic advantages through its synergistic capabilities and efficient decomposition of hydroperoxides.
