Polyurethane (PU) foams are ubiquitous in modern life, found in everything from comfortable furniture and automotive seating to insulation and packaging. Their versatile properties, including flexibility and cushioning, are highly valued. However, like many organic polymers, PU foams are susceptible to degradation caused by oxidation, which can manifest as discoloration, loss of mechanical strength, and brittleness over time. NINGBO INNO PHARMCHEM CO.,LTD. understands the importance of preserving these valuable materials, and our Antioxidant 1135 plays a vital role.

Antioxidant 1135, also known by its chemical name Octyl-3,5-di-tert-butyl-4-hydroxy-hydrocinnamate, is a liquid hindered phenolic antioxidant specifically formulated to address the challenges of polymer stabilization. Its unique structure allows it to effectively neutralize free radicals that initiate oxidative degradation processes. For polyurethane systems, this translates into tangible benefits, particularly in preventing the formation of peroxides within polyols during storage. Peroxide formation can compromise the quality of the PU product and lead to processing issues.

Furthermore, the practical application of antioxidant 1135 for polyurethane foam stabilization extends to the manufacturing process itself. During the foaming stage, elevated temperatures and chemical reactions can accelerate degradation. Antioxidant 1135 helps to prevent 'scorching' – a common issue where the foam darkens or discolors due to thermal degradation. This ensures that the final foam product retains its intended color and structural integrity, meeting aesthetic and performance standards.

The convenience of Antioxidant 1135 as a liquid additive cannot be overstated. Unlike solid additives, it can be easily pumped and metered, simplifying handling and ensuring homogeneous dispersion throughout the PU formulation. This ease of use is a significant advantage in high-volume manufacturing. The low volatility antioxidant for polymers also ensures that it remains effective throughout the material's lifecycle, providing lasting protection against oxidative attack.

When considering the selection of stabilizers, the concept of antioxidant 1135 synergistic effects is critical. Often, Antioxidant 1135 is used in combination with other additives, such as phosphites or UV stabilizers, to create a comprehensive protection package. This multi-pronged approach can offer superior performance compared to single additive systems. NINGBO INNO PHARMCHEM CO.,LTD. advocates for this holistic approach to material protection, ensuring that our customers receive the most effective solutions.

In summary, for manufacturers seeking to enhance the durability and processing characteristics of their polyurethane foams, the inclusion of Antioxidant 1135 is a strategic choice. Its efficacy in preventing oxidation and scorching, coupled with its convenient liquid form and compatibility, makes it an indispensable tool in the pursuit of high-quality, long-lasting PU products.
