In the realm of polymer science, maintaining material integrity against degradation is paramount. Antioxidants play a crucial role in this, and Antioxidant GA-80 stands out as a high-performance solution. This high molecular weight hindered phenolic antioxidant, readily available from reputable manufacturers in China like NINGBO INNO PHARMCHEM CO.,LTD., offers a compelling combination of properties and applications that benefit a wide range of polymer-based products.

Antioxidant GA-80 (CAS No. 90498-90-1) is characterized by its appearance as a white to off-white powder. Its purity, with an assay typically above 97.00%, ensures effective performance. Key specifications include low volatility (max 0.50%), minimal ash content (max 0.10%), and a melting point range of 110.00°C to 125.00°C, all indicative of its thermal stability. Furthermore, its high transmittance at visible wavelengths (e.g., ≥98% at 500nm) suggests excellent optical clarity when incorporated into polymers, a vital trait for many applications.

The primary function of Antioxidant GA-80 is to protect polymers from oxidative degradation. It is particularly effective in materials like polypropylene (PP), high-density polyethylene (HDPE), low-density polyethylene (LDPE), acrylonitrile butadiene styrene (ABS), and polyethylene terephthalate (PET). Its role as a hindered phenolic antioxidant makes it a robust free radical scavenger, interrupting the auto-oxidation cycle and preventing the deterioration of mechanical properties, color, and overall material integrity. This makes it a staple in advanced plastic stabilizers.

Its application rate typically ranges from 0.1% to 0.5%, depending on the specific polymer and the desired level of protection. The compound is also noted for its synergistic performance when combined with secondary antioxidants, such as thioethers, which enhances its long-term heat stability. This makes it an excellent choice for polymer processing enhancement where materials undergo demanding thermal conditions.
