DOS Plasticizer For Pvc Wire

Dioctyl Sebacate (DOS), also known as di(2-ethylhexyl) sebacate (DEHS or BEHS), is a high-performance cold-resistant PVC plasticizer renowned for its exceptional plasticizing efficiency and low volatility. This colorless or light yellow transparent oily liquid not only performs well in cold environments but also maintains stability at high temperatures. Thanks to its superior insulation properties and strong resistance to weathering, DOS is an excellent choice for manufacturing cold-resistant wire and cable materials, artificial leather, films, planks, and sheets.

Often used in combination with phthalate plasticizers, DOS serves as a low-temperature plasticizer for synthetic rubbers and is widely utilized in the production of PVC toys. Beyond its role as a plasticizer, DOS is employed as a lubricant in jet engines and in solid propellant systems, where it enhances mechanical properties, reduces the glass transition temperature (Tg), and increases elongation at low temperatures. It also improves the fluidity and leveling of propellant paste during processing, with typical usage ranging from 10% to 40% by weight of the binder.

DOS Plasticizer For Pvc Wire (DOS)'s versatility extends to other industries as well. It is used in Dot 5 brake fluid, ester-based engine oils and additives, and even as a seed particle for particle image velocimetry (PIV). Additionally, it serves as a model compound for creating stable aerosols. Compliant with FDA CFR 21 for food contact materials, Dioctyl Sebacate is also a valuable ingredient in personal care products like deodorants, antiperspirants, makeup, skin conditioners, lotions, and sunscreens, where it imparts a silky feel and smooth application.
