The application of DMI in the field of plastic manufacturing

DMI is widely applied in the field of plastics. DMI can be used not only as a solvent or plasticizer to improve the processability and flexibility of plastics but also as a BTX extractant to purify raw materials, play a significant role in the preparation of special polymers, and enhance the surface properties of plastics. Here are the specific applications of DMI in the plastic field:

1.Organic solvent or plasticizer

DMI, as a strongly polar aprotic solvent, possesses excellent solvency and thermal stability. With these characteristics, DMI is often used as a solvent or plasticizer in polymer synthesis and processing. During polymer production, DMI can promote the mixing of raw materials and catalysts, enhancing the chemical and mechanical properties of the polymer. Additionally, as a plasticizer, DMI can improve the flexibility of plastics.

2.Plastic film processing

DMI plays a significant role in the processing of plastic films. For example, during the film-forming process of polyimide resins and polysulfone resins, the use of DMI can make plastic films more uniform and improve their quality and performance.

3.BTX extractant

DMI can dissolve aromatic compounds and unsaturated hydrocarbons but not alkanes, making it an excellent BTX extractant. In plastic production, aromatic hydrocarbons such as BTX are often used as raw materials or solvents. DMI's extraction capability can indirectly increase the production capacity and quality of plastics.

4.Improving the surface properties of plastics

DMI can be used as a surface treatment agent to improve the adhesion strength between ABS, polyimide, polyphenylene sulfide resin, polytetrafluoroethylene, and other materials with epoxy resin adhesives. This property of DMI can enhance the adhesion and reliability of plastic products during the processing and compounding process.
