In the vast world of plastics, durability and performance are paramount. From everyday packaging to high-stress automotive components, the ability of plastics to withstand degradation is key to their utility. Oxidation, driven by heat and exposure to oxygen, is a primary cause of plastic failure, leading to discoloration, embrittlement, and loss of mechanical properties. Antioxidants are essential for combating this, and Antioxidant 1520 offers a highly effective solution for enhancing plastic durability and processing.

Antioxidant 1520 is a liquid phenolic antioxidant designed to provide robust processing and long-term thermal stabilization for a wide range of plastics. Its unique chemical structure allows it to effectively neutralize free radicals generated during high-temperature processing, such as extrusion and injection molding. This prevents thermal degradation, ensuring that the plastic maintains its intended melt flow characteristics, mechanical strength, and appearance. The quest for improved plastic processing efficiency often leads to the adoption of advanced stabilizers like this.

A significant advantage of Antioxidant 1520 is its non-staining and non-discoloring properties. This is particularly crucial for plastics used in visible applications or in conjunction with other colored materials where color integrity is essential. By preventing the formation of chromophores that cause discoloration, it helps maintain the aesthetic appeal of plastic products, from consumer goods to high-tech electronic casings. Its suitability for food contact approved plastics further broadens its application scope.

The low volatility of Antioxidant 1520 ensures its persistent presence within the plastic matrix throughout both processing and end-use. This sustained protection is vital for long-term thermal stability, safeguarding the plastic against gradual degradation over time. Its excellent compatibility with various polymer types, including polyolefins, styrenics, and engineering plastics, makes it a versatile additive for a broad spectrum of plastic formulations. This makes it a go-to for plastic durability enhancement.

Incorporating Antioxidant 1520 at recommended dosages (0.05-0.3%) can significantly extend the service life of plastic products, reduce scrap rates during processing, and ensure consistent product quality. It can also be used in combination with other stabilizers to create synergistic blends that offer even greater protection against various degradation pathways.
