For professionals in the polymer industry, understanding the precise technical specifications of additives is crucial for successful formulation and processing. Composite Antioxidant B225, a vital component for polymer stabilization, offers a unique combination of properties that significantly enhance processing efficiency and product quality. This article delves into the key technical data associated with Composite Antioxidant B225, providing insights valuable to R&D scientists and production engineers seeking to optimize their material performance.

Composite Antioxidant B225 is a physical blend of Antioxidant 1010 and Antioxidant 168, typically in a 1:1 ratio, designed to offer a synergistic protection mechanism. From a technical standpoint, its performance is often quantified by several key parameters, including appearance, transmittance, volatile content, and ash content. As a manufacturer, we ensure that our Composite Antioxidant B225 consistently meets these high-standard specifications.

Appearance: The product is typically described as a White Powder. This consistent appearance is indicative of a well-controlled manufacturing process and high purity.

Transmittance: Transmittance is a critical measure, especially for applications where color is important. Composite Antioxidant B225 usually exhibits high transmittance values, typically around ≥97% at 425nm and ≥98% at 500nm. These figures demonstrate its minimal impact on the color of the final polymer product, a key requirement for many applications. For those looking to buy additives with good optical properties, these metrics are vital.

Volatile Content: Low volatile content (typically ≤0.3%) is another significant technical advantage. This means that during high-temperature processing, minimal amounts of the antioxidant will evaporate, ensuring that the intended concentration remains in the polymer matrix and reducing potential issues related to volatile organic compounds (VOCs) or plate-out in processing equipment. This characteristic highlights its suitability for demanding industrial use.

Ash Content: A low ash content (typically ≤0.1%) indicates a high degree of purity, with minimal inorganic residue. This is important for applications where contaminants could affect performance or final product quality.

These technical attributes translate directly into practical processing benefits. The high transmittance ensures clarity and color fidelity, while the low volatile content simplifies processing and reduces emission concerns.
