DOP has excellent plasticizing properties that significantly improve the flexibility of polyvinyl chloride (PVC) and other plastics, making the materials easier to process and mold.
DOP's low volatility ensures that harmful substances are minimized during high-temperature processing, making it suitable for use in products that require high processing stability.
DOP's low production cost makes it widely used in large-scale industrial production, especially in construction materials, household goods and industrial products.
DOP has good heat and cold resistance, which ensures that the material maintains its flexibility and service life under different temperature conditions, and is widely used in wire and cable insulation materials.
Soluble in general organic solvents and hydrocarbon. Slightly soluble in glycerol and ethylene glycol.
Used in industies such as plastics, rubber, paint, lubricant, and emulsifier, etc.
