Polyolefins, such as Polyethylene (PE) and Polypropylene (PP), are ubiquitous in modern manufacturing due to their versatility, cost-effectiveness, and excellent physical properties. However, these polymers are susceptible to degradation during high-temperature processing, which can lead to reduced molecular weight, cross-linking, and undesirable discoloration. For R&D scientists and procurement managers working with polyolefins, Antioxidant 168 (CAS 31570-04-4) is an essential additive for ensuring optimal processing stability and end-product quality. As a leading manufacturer in China, we specialize in providing high-purity Antioxidant 168 to meet these critical industry demands.

Antioxidant 168 is a highly effective phosphite ester, functioning as a secondary antioxidant. Its primary role in polyolefins is to decompose hydroperoxides formed during melt processing. These hydroperoxides, if left unchecked, can initiate chain scission or cross-linking reactions, compromising the mechanical properties and processing characteristics of PE and PP. By acting as a potent hydroperoxide decomposer, Antioxidant 168 safeguards the polymer's molecular structure, maintaining its integrity through demanding extrusion and molding operations.

The synergistic effect of Antioxidant 168 with primary antioxidants, such as hindered phenols, is particularly beneficial for polyolefins. This combination provides comprehensive protection against thermo-oxidative degradation, extending the service life of the finished products. For procurement managers looking to buy Antioxidant 168, our direct sourcing from a China-based manufacturer ensures access to competitive pricing and a reliable supply of grades with ≥99% purity. This is crucial for achieving consistent product performance in applications ranging from films and fibers to pipes and automotive parts.

Incorporating Antioxidant 168 into polyolefin formulations not only enhances processing stability but also contributes to better color retention. This means that products made from stabilized polyolefins are less prone to yellowing, maintaining their aesthetic appeal over time. Whether you are developing packaging materials, consumer goods, or industrial components, our Antioxidant 168 offers a proven solution for material stabilization. We offer tailored support to help you integrate this additive effectively into your manufacturing processes.

To ensure you are using the most effective additive package for your polyolefin applications, consider the benefits of sourcing Antioxidant 168 directly from a trusted Chinese manufacturer. We are committed to delivering exceptional quality and value.
