DINP is a C9 phthalate plasticizer, produced from INA (Isononyl Alcohol) and PA (Phthalic Anhydride). It appears as a clear, colorless, and almost odourless oily liquid with solubility in most organic solvents. Compared with DOP, DINP typically requires a slightly higher dosage to achieve similar plasticizing efficiency. However, it offers superior electrical insulation, durability, migration resistance, and low-temperature flexibility. The longer carbon chain structure improves stability and reduces volatility. At the same Phr level, DINP-plasticized products generally demonstrate improved tensile strength, elongation, durability, and low-temperature flexibility than DOP-plasticized products.
