In the production of plastic films and sheets, maintaining material integrity throughout the manufacturing process and during end-use is paramount. Polymers used in these applications must withstand processing heat and environmental exposure without significant degradation. NINGBO INNO PHARMCHEM CO.,LTD. offers specialized antioxidant solutions that are vital for achieving optimal performance in film and sheet applications.

The manufacturing of plastic films and sheets typically involves high-temperature extrusion and calendering processes. During these operations, polymers can undergo thermal oxidation, leading to chain scission, cross-linking, and the formation of undesirable by-products. These changes can manifest as reduced molecular weight, loss of tensile strength, increased brittleness, and discoloration, all of which negatively impact the final product quality. Antioxidants are critical for mitigating these issues. Antioxidant 697, with its favorable thermal stability and low volatility, plays a key role in safeguarding polymers during these processes.

As a polymer stabilizer, Antioxidant 697 works by neutralizing free radicals that are generated at elevated temperatures. This prevents the propagation of degradation reactions, ensuring that the polymer retains its intended molecular weight and properties. Its non-discoloring nature is particularly advantageous for films and sheets where clarity and color are essential attributes, such as in packaging or display applications. The focus on high purity antioxidant additive ensures consistent results.

The metal deactivating capabilities of Antioxidant 697 also contribute to its effectiveness in film and sheet manufacturing. Metal ions present from catalysts or equipment can significantly accelerate degradation. By chelating these metal ions, Antioxidant 697 inhibits their catalytic activity, providing an added layer of protection and contributing to the overall anti-yellowing performance and weather resistance of products.

Furthermore, the compatibility of Antioxidant 697 with a wide range of polymers, including polyolefins like polyethylene and polypropylene, as well as ABS and polyesters, makes it a versatile choice for diverse film and sheet applications. It can be effectively incorporated into formulations to improve processing stability, reduce gel formation, and enhance the final product's mechanical properties, such as tensile strength and elongation. Its utility in antioxidant 697 polymer stabilizer applications is well-recognized.
