For professionals in the plastics industry, a thorough understanding of chemical specifications is vital for formulating high-performance PVC products. Plasticizers, essential additives that impart flexibility, have specific technical parameters that dictate their suitability for various applications. This article aims to demystify these specifications and guide you in selecting the optimal plasticizer from reputable manufacturers and suppliers.

Key specifications for plasticizers include Ester Content, Freezing Point, Acid Value, Loss on Heating, Flash Point, Density, and Color (often measured on the Pt-Co scale). For instance, a high Ester Content (e.g., ≥99%) typically indicates higher plasticizing efficiency. The Freezing Point is crucial for determining a plasticizer's performance in low-temperature environments; a lower freezing point (e.g., -25°C or below) signifies better cold resistance. Acid Value, measured in mg KOH/g, indicates the presence of free acids, with lower values generally preferred for stability and reduced corrosion potential.

The Loss on Heating (or moisture content) should be minimal to ensure consistent performance and prevent issues during processing. A high Flash Point (e.g., ≥160°C) indicates lower volatility and improved safety during handling and processing. Density provides information on the product's mass per unit volume, which is important for volume-based dosing. Color, often assessed using the Platinum-Cobalt (Pt-Co) scale, indicates the degree of discoloration, with lighter colors (e.g., 20-50 Pt-Co) generally preferred for clear or light-colored PVC products.

Our advanced composite plant ester plasticizer, for example, boasts an Ester Content of ≥99%, a low freezing point of -25°C min, and a low Acid Value (≤0.5 mg KOH/g), alongside excellent low color properties. These specifications make it an ideal candidate for demanding PVC applications requiring superior low-temperature flexibility, stability, and minimal visual impact. When you choose to buy from us, a leading manufacturer and supplier in China, you are assured of products that meet stringent quality criteria.
