Product Overview

Bis(2-ethylhexyl) sebacate is a clear, oily liquid plasticizer often abbreviated as DOS. It is valued for outstanding low-temperature performance, excellent permanence and very good resistance to extraction. In formulation systems, DOS helps improve flexibility, durability and processing behavior, especially in applications where cold resistance is important.

Colorless to pale yellow liquid. Relative density: 0.910(25℃), melting point: -55℃, boiling point: 248℃(4×133.322Pa), refractive index: 1.447(20℃).

It is insoluble in water but soluble in organic solvents such as ethanol, ether and benzene. It can be mixed and used with ethyl cellulose, polystyrene, polyethylene, polyvinyl chloride, vinyl chloride-acetate copolymer, etc. Good cold resistance.

Performance Benefits

Excellent cold resistance: ideal for flexible products exposed to low temperatures.
Low volatility: supports long-term permanence in finished goods.
Good plasticizing efficiency: improves softness and flexibility.
Reliable processing: works well in extrusion, calendaring and compounding.

Typical Applications

Wire and cable compounds
Flexible PVC films and sheets
Synthetic leather and coated fabrics
Seals, gaskets and low-temperature flexible parts
Specialty formulations requiring durable cold flexibility

It can be used as a low-temperature plasticizer and also in synthetic lubricating oil for jet engines. It is applicable to polyvinyl chloride, vinyl chloride copolymers, nitrocellulose, ethyl cellulose and synthetic rubber, etc. It has a high plasticizing efficiency and low volatility. It not only has excellent cold resistance, but also good heat resistance, light resistance and electrical insulation. Moreover, it has good lubricity when heated, making the appearance and hand feel of the products good. It is particularly suitable for making cold-resistant wire and cable materials, artificial leather, films, plates, sheets, etc.
