Dioctyl Phthalate (DOP), systematically named bis(2-ethylhexyl) phthalate and identified by CAS 117-81-7, is the most widely consumed general-purpose phthalate ester plasticizer in the global polymer processing industry. As a premier DOP manufacturer and supplier, we deliver high purity (≥99.5% ester content) industrial-grade dioctyl phthalate manufactured under rigorous quality control protocols to ensure consistent plasticizing efficiency, excellent low-temperature flexibility, and outstanding compatibility with a broad range of resin systems. |
DOP remains the benchmark plasticizer for flexible PVC compounding worldwide, valued for its exceptional balance of performance, processability, and cost-effectiveness. With good mixing performance, high plasticizing efficiency, low volatility, excellent low-temperature softness, superior water resistance, high electrical performance, and robust heat and weather resistance, DOP CAS 117-81-7 delivers reliable, predictable results across diverse polymer processing operations. |
Our DOP plasticizer is a colorless transparent oily liquid with tightly controlled acid value (≤0.01 mg KOH/g), minimal moisture content (≤0.05 wt%), and excellent volume resistivity (≥1 × 10⁹ Ω·m) — critical parameters for high-quality flexible PVC production. Available for bulk supply and wholesale procurement, our factory-direct pricing structure eliminates intermediary markups, providing PVC compounders, rubber processors, and industrial distributors with a decisive cost advantage. |
