Uniplex DOS

Technical DataSheet | Supplied by Lanxess

Uniplex DOS is Di-(2-Ethylhexyl) Sebacate. Acts as a plasticizer. It exhibits an advantageous blend of properties such as an excellent low temperature flexibility combined with a low volatility. It has a low viscosity, which, in combination with its weak ability to solvate PVC, has a positive effect on the initial viscosity and storage stability of plastisols, a lower volatility compared to the corresponding adipate. It help imparts a very good low-temperature resistance to suitably plasticized compounds; this effect is clearly noticeable even when Uniplex DOS is used in combination with other plasticizers, very good light stability to PVC compound. Compatible with polyvinyl chloride (PVC), polystyrene (PS), cellulosics (cellulose acetate), and rubber (chloroprene, nitrile, butadiene). It has a shelf life of at least 12 months.
