Diisodecyl Phthalate (DPHP) is an organic compound belonging to the phthalate class of plasticizers.
The following are its main features:
The physical characteristics of Diisodecyl Phthalate (DPHP):
DPHP is a viscous liquid at room temperature.
The boiling point is up to 420℃ and the flash point is 232℃.
The relative density is 0.97 (20℃).
Insoluble in water, but soluble in most organic solvents.
The environmental protection features of Diisodecyl Phthalate (DPHP):
Low volatility: Compared with some other plasticizers, DPHP is less volatile, which means that it does not evaporate into the air in large amounts during product use, thus reducing pollution to the surrounding environment.
Good migration resistance: DPHP has good migration resistance, which means that it is not easy to migrate from plastic products to other substances, such as soil or water, thus reducing the potential impact on the ecological environment.
Excellent electrical properties: DPHP has good electrical properties, which makes its application in many electrical products possible, such as cable and wire insulation.
Aging resistance: DPHP has good aging resistance and can maintain stable performance in long-term use, which extends the service life of products made of DPHP.
The application field of Diisodecyl Phthalate (DPHP):
DPHP plays a crucial role in the plastics industry, especially as a plasticizer for polyvinyl chloride (PVC).
High temperature and aging resistance: Because of its excellent high temperature and aging resistance, DPHP is often used in products requiring higher use temperatures, such as wire and cable sheaths, agricultural films, transportation belts, etc.
Electrical insulation performance: DPHP has good electrical insulation and is suitable for products requiring electrical insulation, such as automotive interior decoration materials.
Application of plasticizing paste: DPHP as a plasticizer of plasticizing paste, can give the paste good fluidity, long-term storage viscosity change is small.
Synthetic rubber plasticizer: used as a plasticizer for synthetic rubber, which has no adverse effect on the vulcanization of rubber compound.
In the rubber industry, used as a rubber softener to improve the processing and physical properties of rubber, such as tensile strength, wear resistance and aging resistance. The addition of Diisodecyl Phthalate (DPHP) makes rubber products more soft, elastic, and has better cold resistance and heat resistance, so it is widely used in automobile tires, conveyor belts, seals and other products.
In the field of paints and coatings, used as an additive for paints and coatings to improve their leveling, adhesion and weather resistance. The addition of Diisodecyl Phthalate (DPHP) makes paints and coatings easier to apply, smoother and more uniform, and has better durability and weather resistance.
