DOP dioctyl phthalate, full name dioctyl phthalate, is a commonly used plasticizer with a chemical formula of C24H38O4. In its molecular structure, there are two ester groups that interact with each other through the conjugation of phthalic acid. It is a colorless, transparent liquid with good solubility and plasticizing properties. It is often used as a plasticizer for various synthetic resins such as PVC (polyvinyl chloride). It can improve the flexibility and processability of plastics through dissolution and penetration.
DOP dioctyl phthalate is the most widely used plasticizer. In addition to cellulose acetate and polyvinyl acetate, it has good compatibility with most synthetic resins and rubbers used in the industry. This product has good comprehensive properties, good mixing properties, high plasticizing efficiency, low volatility, good low-temperature flexibility, water extraction resistance, high electrical properties, good heat resistance and weather resistance. As a main plasticizer, this product is widely used in the processing of various soft products of polyvinyl chloride, such as films, sheets, artificial leather, cable materials, and molded products. This product is non-toxic and can be used for packaging materials in contact with food, but it is not suitable for fatty food packaging materials because it is easily extracted by fat. It can also be used in nitrocellulose paint to make the paint film have elasticity and high tensile strength. Among various synthetic rubbers, DOP dioctyl phthalate also has a good softening effect. In addition, DOP is also used as a condensing agent, antifriction agent, organic solvent, gas chromatography stationary liquid, etc.
