Product Description

Product Introduction

DOP, short for Dioctyl Phthalate, is a widely - used member of the phthalate ester family. It is a colorless to light - yellow, transparent, and viscous liquid at room temperature. It has a faint, characteristic odor that is often negligible in its applications.

 

DOP is primarily produced through the esterification reaction of phthalic anhydride and 2 - ethylhexanol. This chemical synthesis process allows for the large - scale manufacturing of DOP to meet the demands of various industries.

 

As a plasticizer, DOP plays a crucial role in modifying the physical properties of polymers. It works by inserting itself between the polymer chains, reducing the intermolecular forces. This results in increased flexibility, softness, and workability of the polymers, especially in polyvinyl chloride (PVC) products.

Product Application

• Plastic Industry: The most significant application of DOP is in the plastic industry, especially in the production of PVC products. It is used to make a wide range of PVC items, including flexible PVC films for packaging food, agricultural products, and industrial goods. In PVC pipes, DOP helps to improve the flexibility of the pipes, making them more resistant to cracking during installation and use. It is also used in PVC flooring, artificial leather, and wire and cable insulation, enhancing their flexibility and durability.
• Rubber Industry: DOP can be used as a softening agent in the rubber industry. It helps to improve the processing properties of rubber compounds, such as reducing viscosity and increasing plasticity. This makes it easier to mold and shape rubber products. Additionally, it can enhance the low - temperature performance of rubber, making it more flexible in cold environments.
• Paint and Coating Industry: In paints and coatings, DOP can act as a coalescing agent. It helps the polymer particles in water - based paints to fuse together during the drying process, resulting in a smooth and continuous film. It also improves the flexibility and adhesion of the paint film, making it more resistant to cracking and peeling.
• Adhesive Industry: DOP is used in adhesives to improve their flexibility and adhesion properties. It can adjust the viscosity of the adhesive, making it easier to apply, and also enhance the bonding strength between different materials. For example, in contact adhesives used for bonding plastics, rubbers, and textiles, DOP can play a crucial role in achieving a strong and durable bond.
