DOP Production Line

What is DOP?

DOP is a common plasticizer primarily used to plasticize PVC resins. It is widely used in cables, hoses, artificial leather, floor coverings, adhesives and coatings.

DOP Production Line Equipment Configuration

1. Reactor: Core equipment for the esterification reaction.
2. Condenser: Condenses water vapor or unreacted alcohol produced during the reaction.
3. Water separator: Separates water and alcohol, promoting equilibrium in the esterification reaction.
4. Vacuum system: Lowers the boiling point, facilitates the removal of by-product water, and increases the reaction rate.
5. Neutralization and washing unit: Uses alkali solution to neutralize by-product acid, improving product stability.
6. Filter: Removes impurities and catalyst residues.
7. Storage tank: Raw material tanks and finished product tanks.

Relationship Between DOP and Resin

1. Imparts flexibility

Resin molecular chains interact strongly, making them less mobile. DOP molecules penetrate the intersegmental gaps between resin chains, weakening the intersegmental forces and making them more flexible.

2. Improves processability

DOP lowers the resin's glass trasition temperature and viscosity, making it easier to flow and shape during processing. This facilitates processes such as extrusion, injection molding, and calendering.

3. Enhances low-temperature resistance

Resins tend to become brittle at low temperatures. DOP maintains their flexibility and improves low-temperature performance.

4. Adjusts performance balance

While DOP improves flexibility, it also reduces the resin's hardness and strength. In practical applications, DOP is often used in combination with other plasticizers to achieve a balanced performance balance.
