Dioctyl Phthalate (DOP) is a colorless or light yellow transparent oily liquid with a special odor and one of the most widely used plasticizers in plastic processing.

Dioctyl Phthalate (DOP) has the following characteristics:

Insoluble in water, soluble in most organic solvents and hydrocarbons, slightly soluble in glycerol, ethylene glycol.
Good overall performance, high growth efficiency, low volatility, UV resistance, cold resistance, so that it can improved the product’s softness and electrical properties.
It has good compatibility with most industrial resins, especially neoprene rubber, butyl rubber, nitrile rubber and polyvinyl chloride.

The application of Dioctyl Phthalate (DOP) in building materials:

As a plasticizer, widely used in the manufacture of floor, sound insulation materials and other building materials. The addition of DOP can significantly increase the flexibility and durability of these materials, improve their processability, and make them more suitable for various environmental conditions.
The use of DOP in building materials can enhance the resistance of the material to ultraviolet light, thus improving the durability and aesthetics of the building. This is particularly important for external wall materials, waterproof materials, etc.

The application of Dioctyl Phthalate (DOP) in food packaging:

DOP can increase the heat and cold resistance of packaging materials, so that food packaging can better adapt to various storage and transportation conditions.
By adding DOP, the packaging material is softer and less prone to breakage, enhancing the overall durability of the package.
Improved packaging material properties help maintain the freshness and quality of food, thereby extending the shelf life of food.

The application of Dioctyl Phthalate (DOP) in medical field:

In the field of medicine, mainly used in the production of medical materials such as soft capsules and infusion bags. This substance has good stability and plasticity, which can effectively improve the flexibility and durability of medical materials.
In addition, the use of DOP as a plasticizer in medical control equipment is also more widespread, especially in equipment requiring steam disinfection, and is more ideal than some other plasticizers.

The application of Dioctyl Phthalate (DOP) in cosmetics:

Used in a variety of cosmetics, mainly including moisturizers, lipsticks and other products. Its main function is to increase the smoothness and ductility of the product and improve the use experience of the product.
In addition, DOP in perfume manufacturing also contributes to the stability and durability of perfumes.

The application of Dioctyl Phthalate (DOP) in rubber industry:

Through the plasticizing action of DOP, the flexibility of rubber has been significantly improved, and the material is not easy to break during stretching and bending. At the same time, the ductility of the rubber is also improved, allowing it to withstand greater deformation without causing structural damage.
DOP can also improve the wear resistance of rubber materials and extend the service life of rubber products in high-friction environments. Especially in automobile tires and industrial rubber products, the addition of DOP significantly improves the wear resistance of products and reduces the degree of wear during long-term use.

The application in cable sheath and electronic device protective sleeve:

The application of DOP in cable materials is mainly reflected in improving the flexibility and electrical insulation properties of cable. Due to its good softness and electrical insulation, DOP plasticized cable material can show low electrical conductivity and excellent insulation effect in high electric field environment.
In addition, DOP can also reduce the glass transition temperature of the cable material, so that the cable still maintains good elasticity and flexibility under low temperature conditions, suitable for use in cold climates.

In electronic devices, mainly used to improve the aging resistance and chemical resistance of materials. Its plasticizing effect can improve the wear resistance and service life of rubber materials, which is particularly important for electronic devices that need to work in harsh environments for a long time.
In addition, DOP enhances the flexibility and ductility of the device, making it less vulnerable to damage when subjected to physical stress.
