NINGBO INNO PHARMCHEM CO.,LTD. provides essential chemical products with detailed specifications to ensure optimal application performance. Epoxidized Soybean Oil (ESBO) is a vital additive for the PVC industry, and understanding its technical parameters is key to successful formulation. The specifications of ESBO, such as its epoxide value, acid value, purity, and physical appearance, dictate its effectiveness as a plasticizer and stabilizer.

The epoxide value of ESBO is a critical parameter, typically ranging from 6.0% or higher. A higher epoxide value indicates a greater degree of epoxidation, which directly correlates with its efficiency as both a plasticizer and a secondary heat stabilizer for PVC. Coupled with a low iodine value (≤ 6.0%), which signifies minimal unsaturation remaining, ESBO demonstrates excellent stability. Furthermore, a low acid value (≤ 0.50 mgKOH/g) is indicative of minimal free fatty acids, preventing unwanted reactions and ensuring product longevity.

The purity of ESBO, often around 99.9%, ensures consistent performance and minimizes the presence of impurities that could negatively affect PVC properties or processing. Visually, ESBO is a transparent light yellow oil liquid at normal temperatures, though it can solidify below 5°C. Its density is typically between 0.988-0.998 g/cm³ at 20°C, and it possesses a high flash point (≥ 280°C), indicating good thermal stability and safety during handling and processing.

Manufacturers looking to buy epoxidized soybean oil for their PVC formulations can rely on the detailed specifications provided by NINGBO INNO PHARMCHEM CO.,LTD. These technical details are crucial for predicting the performance of ESBO in various applications, from films and cables to automotive parts. Understanding these parameters allows for precise formulation adjustments, ensuring that the final PVC products meet all required standards for flexibility, durability, and stability. Exploring the buy options for high-quality ESBO with these specifications is a strategic step for any PVC manufacturer.
