Product Introduction:
Dioctyl Phthalate (DOP), commonly referred to by its acronym, is an ester compound widely utilized as an additive plasticizer in plastic and rubber industries – especially polyvinyl chloride plastics. It possesses both two octyl (C8H17) substituents and thus belongs to its ester family of compounds.
Dioctyl Phthalate (DOP) is an insoluble, colorless or pale yellow oily liquid at room temperature with an aromatic scent, insoluble in water but soluble in many organic solvents such as alcohols, ethers and benzene.
Dioctyl Phthalate boasts excellent physical and chemical properties. With a boiling point of around 386degC and melting points as low as 50degC, as well as good heat resistance and cold resistance properties. As it remains liquid over an extensive temperature range it makes an ideal plasticizer material. Furthermore, its density of around 0.986g/cm3 paired with excellent electrical insulating properties means its use in products like cables or insulation materials has increased considerably in recent years.
Chemical stability-wise, Dioctyl Phthalate has proven itself remarkably stable to oxidation, acid and alkali attacks and high temperatures; it may however volatilize or degrade at higher temps but its volatility remains relatively low allowing its plasticizing effects in plastic products to continue for an extended period.
Dioctyl Phthalate can slowly migrate or volatilize over time, altering physical properties of materials. Due to poor light stability and UV radiation exposure, Dioctyl Phthalate’s plasticizing effect could become compromised over time and eventually lose all plasticizing effect altogether.
Dioctyl Phthalate’s stable properties and relatively reasonable cost make it widely applicable across a range of fields, not just PVC plastics plasticizing effects. As well as PVC plastic plasticization effects it also serves as an ingredient or solvent in cosmetics, paints, coatings textiles and agricultural products – as well as providing plasticizing properties in PVC plastics themselves.

Dioctyl Phthalate (DOP) is a widely used plasticizer and is widely used in many fields due to its low cost and good plasticizing properties.
1. Plastic processing field
Dioctyl Phthalate is most widely used in the field of plastic processing, especially in the processing of polyvinyl chloride (PVC) resin. PVC is one of the most commonly used plastics. It can significantly improve the flexibility, ductility and processing performance of PVC, allowing PVC to be made into plastic products of various shapes and uses.
These products include construction pipes, films, plates, artificial leather, agricultural films and packaging materials, etc., which are widely used in construction, agriculture, packaging and other industries. By adding Dioctyl Phthalate, the glass transition temperature of PVC decreases and the plastic becomes softer, making it suitable for making a variety of soft products such as hoses and cable sheaths.
2. Polymer processing
In addition to PVC resin, Dioctyl Phthalate is also widely used in the processing of other polymers, such as chemical fiber resin, acetate resin, ABS resin and rubber. In these materials, it not only increases the material’s softness but also improves its processing properties.
For synthetic fibers, polyester fibers and fabrics, the addition of Dioctyl Phthalate helps improve their feel and tear resistance, making the fabrics more elastic and durable. In rubber processing, it can be used as a plasticizer to improve the softness, elasticity and durability of rubber products, and is widely used in industrial fields such as automobiles and aviation.
3. Coatings and paints
In the coating and paint industry, Dioctyl Phthalate is used as a plasticizer to improve the fluidity, flexibility and adhesion of coatings, especially in some coating products with higher elasticity. It can improve the flexibility of the coating, making it less likely to break during use. It is suitable for coating surfaces such as wood, metal, and plastic.
It can also increase the gloss, water resistance and pollution resistance of the coating, extending the service life of the coating. However, because it may be harmful to the environment, some environmental regulations require its use to be reduced in coatings, which has promoted the research and development of alternative plasticizers.
4. Electrical field
Electrical grade Dioctyl Phthalate has good electrical insulation properties, ensuring the safety and reliability of wires and cables during use. The outer layer of the cable usually needs to maintain a certain degree of flexibility and anti-aging properties. By improving the physical properties of the cable, the cable is less likely to be brittle or cracked during long-term use, especially in low-temperature environments. It can still maintain good flexibility. It is commonly used in the production of power cables, communication cables and other electronic equipment.
5. Food packaging and medical hygiene
In the food and medical industries, Dioctyl Phthalate also has certain applications as a plasticizer. Under strict control of usage amount and conditions, it is used in non-fat food packaging materials (such as flexible packaging films, food bags, etc.) to help packaging materials maintain softness and ductility.
In the medical field, Dioctyl Phthalate is mainly used to manufacture disposable medical devices (such as infusion tubes, catheters, etc.) and medical packaging materials to ensure their durability and ease of use.
6. Other applications
In addition to the main applications mentioned above, Dioctyl Phthalate is also used in many other fields. For example, in the production of synthetic rubber, it is used as a softener to help improve the rubber’s resilience and reduce compression set, thereby improving the rubber’s wear resistance and comfort. In other chemical applications, it also serves as a solvent, condensing agent, antifriction agent, etc., and is widely used in the manufacture of paints, coatings, lubricants, and gas chromatography fixatives.
1. Efficiency
Dioctyl phthalate is a highly efficient plasticizer with excellent plasticizing properties and is known for significantly increasing the flexibility and ductility of other materials such as plastics, rubber and wood. By lowering the glass transition temperature of the polymer, it is able to maintain flexibility at low temperatures without losing softness/ductility; making this plasticizer suitable for manufacturing a variety of flexible products such as cables/hoses/artificial leather/ Film, etc.
2. Ease of use
Dioctyl phthalate’s broad compatibility enables it to form stable solutions with a variety of polymers, especially polyvinyl chloride (PVC), making it one of the most widely used plasticizers in the PVC industry. In addition, its plasticizing effect is also suitable for polyester, acetate resin, ABS resin, chemical fiber resin, etc., and can achieve better plasticizing effect on various materials.
3. Good processability
Dioctyl phthalate can enhance the processing properties of polymers by lowering processing temperatures, reducing mechanical loads during processing and improving processing efficiency. Because it is in liquid form, dioctyl phthalate can be easily added during the production process for even distribution; thus ensuring consistent product quality.
4. Excellent insulation
Dioctyl phthalate has excellent electrical insulation properties and is often used in electrical fields. This versatile compound can be used in wire and cable production to improve the quality of electrical insulation and ensure safe use during use. It is often used to enhance safety measures such as high-voltage cables and communication lines to prevent aging or embrittlement problems.
5. Low cost
Dioctyl phthalate’s low production costs give it an advantage in price-sensitive markets. Due to this combination of properties and low price, dioctyl phthalate is a plasticizer widely used in industries such as plastics, rubber and coating production.
6. Long-lasting plasticizing effect
Dioctyl phthalate has an excellent long-term plasticizing effect, allowing plastic and rubber materials to remain flexible and ductile for a longer period of time. This makes it suitable for applications requiring consistent performance, such as cables, pipes and packaging materials such as electrical cables that require a long-term plasticizing effect.
