Application Guide:
1. DOS is an excellent cold-resistant plasticizer. It has high growth efficiency, low volatility, and higher stability. It has both excellent cold resistance, good heat resistance, light resistance and electrical insulation. Used in various resins such as polyvinyl chloride, nitrocellulose, ethyl cellulose and synthetic rubber.
2. Especially suitable for making cold-resistant wire and cable materials, high-end food, meat cling film, artificial leather, film, transportation belt, sheet, sheet, etc. Often used with phthalates.
3. As a low-temperature plasticizer for various synthetic rubbers, it has no effect on the vulcanization of rubber.
