What Is Dioctyl Phthalate DOP
Oct 24, 2024| 1. The Definition of dop
DOP (Dioctyl Phthalate) is a combustible non-toxic colorless oily liquid with slight odor. It is a clear, colourless liquid which is slightly more dense than water with a slight but characteristic odour. Dioctylphthalate is miscible with most organic solvents but not soluble in water.
2. Dioctyl Phthalate DOP Plasticizer Uses
It is mainly used in the processing of polywinyl chloride resin.lt can also be used in the procesing of high polymers such as chemicalfiber resin, acetate resin, ABS resin and rubber, as well as paint making, dves, dispersants, etc.Diocy phthalate DOP, an organic ester compound, is one of the mostcommonly used plasticizers. As the most widely used plasticizerin industrny, DOP as good compatlbitywithmost synthetic resins and rubbers usd in industry.It has good comprehensive performance, good mixing performance, high plasticizing eficiengy,low volatlity, good lowtemperature flexibility, water extraction resistance, high electrical performance, good heat resistance and weather resistance.
It has several advantages over some other plasticizers in that it is more economical; it provides the desired changes to physical and mechanicalproperties without causing changes to the chemical structure of the polymer; it jellifies quickly; in lacquer applicaions it serves to eliminatecracks,increase resistance and provide a smooth surface.
3. Applications of Dioctyl Phthalate
Dioctyl phthalate is a phthalate ester which is used in the manufacture of a wide range of plastics and coating products.Dioctyl phthalate is used as a plasticizer in PVC paste and pulp mixtures and as an additive in many other processes.Dioctyl phthalate can be found in many end products including Pvc soles for shoes and slippers, synthetic leather, waterproof membranes,paints, varnishes, floor coverings, door mats and hoses.Dioctyl phthalate is also used in the calendaring process of paper finishing, to produce Pvc granules, as a hydraulic or dielectric fuid incapacitors, in toxicology studies and in risk assessment studies on food contamination.
Plastic industry
Plasticizers
Dioctyl phthalate can be used as a softening agent , such as to make the product easier to rebound and harder to undergo form change underpressure, without affecting of the plastics. DoP possesses its good plasticizing properties thanks to the ability to make the long polimersmolecules to slide against one another.
It is extensively used in processing polyviny choride and ethyicellulose resins to produce plastic film, imitation leather, electric wire, cablewearer, sheet, planet, mould plastic products and used in nitrocelulose paints. it has the applications in the industry ofautomotive, buildingand construction material, flooring, medical device.
Wood coating
It is used in the industrial wood coating to enhance the performance properties of the wood coatings formulations.
Medical devices
Dioctyl phthalate is used a plasticiser in the manufacture of medical and sanitary products, such as blood bags and dialysis equipment. it has atuther and unioue role in blood bags because it actualy helns to prolong the ife ofthe blood itself DEHe also stablises the membranes ofrerblood cells enabling blood product storage in Pvc blood bags for several weeks.
Plastics may contain from 1% to 40% of DOP.
Other uses:
It is also used as a hydraulic fluid and as a dielectric fluid in capacitors.
DOP also finds the application as a solvent in lightsticks.
