Industrial Grade DOS Dioctyl Sebacate Liquid Low Volatility Cold Resistant PVC Plasticizer
Dioctyl Sebacate (DOS) is an excellent cold-resistant plasticizer known for high speed-up efficiency, low volatility, and superior stability. It is an essential additive for high-performance synthetic materials requiring flexibility in low-temperature environments.
- Cold-Resistant Performance: Ideal for wire and cable materials
- Versatile Use: Suitable for high-end food and meat preservation films
- Industrial Applications: Used in artificial leather, films, conveyor belts, plates, and sheets
- Compatibility: Easily combined with phthalate esters; no interference with synthetic rubber vulcanization
DOS is an excellent cold-resistant plasticizer with high growth efficiency, low volatility, and superior stability. It exhibits not only excellent cold resistance but also good heat resistance, light resistance, and electrical insulation properties.
Suitable for various resin esters including polyvinyl chloride, nitrocellulose, ethyl cellulose, and synthetic rubber. Particularly ideal for manufacturing cold-resistant wire and cable materials, high-end food packaging, meat preservation films, artificial leather, films, transport belts, boards, and sheets. Often used in combination with phthalates.
As a low-temperature plasticizer for various synthetic rubbers, DOS has no adverse effect on the vulcanization process of rubber.
