For procurement managers, R&D scientists, and formulation chemists, understanding the precise specifications of chemical raw materials is fundamental to ensuring product consistency, performance, and safety. Epoxy Fatty Acid Methyl Ester (EFAME) is a critical plasticizer for the PVC industry, and its quality is directly tied to its specific technical parameters. As a manufacturer of high-quality EFAME, we believe in transparency and providing our clients with the detailed information they need to make informed decisions.

EFAME, derived from plant oils, is valued for its eco-friendly profile and its ability to enhance PVC properties. However, not all EFAME grades are created equal. Variations in purity, epoxy value, and other physical characteristics can significantly impact its performance in your specific applications. Our manufacturing process is optimized to consistently deliver EFAME that meets rigorous industry standards.

Key Specifications of EFAME and Their Importance:

• Appearance: Our EFAME is typically described as a yellowish to colorless transparent oily liquid. This visual characteristic is an initial indicator of purity and proper processing. Deviations can suggest impurities or inconsistent production.
• Purity (Ester Content): A high purity level, often specified as ≥ 99%, is crucial. High purity ensures that the plasticizer performs as expected without the interference of unwanted by-products, leading to predictable and reproducible results in your formulations.
• Epoxy Value: This parameter, often measured in mol/100g or percentage of oxirane oxygen, indicates the degree of epoxidation. A higher epoxy value generally correlates with better plasticizing efficiency and improved thermal stability for the PVC product. Our EFAME grades offer epoxy values of ≥ 4.0 mol/100g, with specific grades reaching up to 4.5 mol/100g, providing excellent plasticization.
• Acid Value: A low acid value (e.g., ≤ 1.0 mgKOH/g) is essential. High acidity can lead to undesirable side reactions, reduced product lifespan, and potential corrosion issues. Our manufacturing processes ensure very low acid values in our EFAME products.
• Iodine Value: This indicates the level of unsaturation remaining in the ester. A low iodine value (e.g., ≤ 5 gI2/100g) suggests effective epoxidation and greater saturation, contributing to better stability and reduced odor.
• Flash Point: A high flash point (e.g., ≥ 170 °C) is a safety indicator, signifying lower flammability and safer handling during storage and processing.
• Moisture Content: Minimal moisture content (e.g., ≤ 0.5%) is critical, as excess water can negatively affect processing and product quality.
