Main Performance:
 

1. DOS is an excellent plasticizer with good cold resistance. It has a high plasticizing efficiency, low volatility, and higher stability. It not only has excellent cold resistance but also good heat resistance, light resistance, and electrical insulation properties. It is suitable for various resins such as polyvinyl chloride (PVC), nitrocellulose, ethyl cellulose, and synthetic rubber.
2. It is especially suitable for the production of cold-resistant wire and cable compounds, high-grade food and meat cling films, artificial leathers, films, conveyor belts, plates, sheets, etc. It is often used in combination with phthalate esters.
3. As a plasticizer for various synthetic rubbers at low temperatures, it has no impact on the vulcanization of rubber.

Use

1. PVC Products: It is widely used in the production of PVC films, sheets, and cables. It can improve the flexibility, low - temperature resistance, and durability of PVC products, making them more suitable for use in different environments.
2. Rubber Industry: In the rubber industry, it can be used as a processing aid to improve the processing performance of rubber and enhance its physical properties such as tensile strength and elongation at break.
3. Fibers: It is used in the production of some synthetic fibers to improve the softness and handle of the fibers.
4. Other Applications: It can also be used in coatings, adhesives, and inks to improve their performance, such as enhancing the flexibility and adhesion of coatings.
