What is Bis(2-ethylhexyl) sebacate CAS 122-62-3?

Diisooctyl sebacate is an excellent low-temperature plasticizer, a colorless or slightly yellow oily liquid. It has good antioxidant and hydrolysis stability, and is an indispensable additive in the plastics industry. It can be used as a toughening agent and low-temperature plasticizer for plastics, and is also used in lubricant synthesis.

Bis(2-ethylhexyl) sebacate CAS 122-62-3 Use

I. Core use: high-performance cold-resistant plasticizer

Ultra-low temperature PVC products:

Used for polyvinyl chloride (PVC) cable sheaths, automotive cold zone sealing strips, polar equipment shells, etc., and still maintains flexibility at -60℃ (better than ordinary plasticizers).

Special synthetic rubber modification:

Added to nitrile rubber (NBR) and chloroprene rubber (CR), it improves the brittle crack resistance of elastomers in severe cold environments (such as spacecraft seals).

Food/medical grade soft products:

Comply with FDA 21 CFR 175.300 standards, used for food packaging films, medical infusion tubes, etc. (low migration, non-toxic exudation).

II. Special industrial additives

Aviation lubricant base oil:

As the core component of synthetic ester lubricants, it is used in jet engines and helicopter rotor systems (-50℃ low-temperature start-up, high-temperature stability up to 200℃).

Military explosive stabilizer:

Reduces sensitivity in nitroglycerin (NG)-based explosives to prevent accidental detonation during transportation/storage (such as propellant modification).

Polymer material processing aid:

Improve the melt fluidity of engineering plastics (such as nylon) and reduce injection molding defects.

III. Functional material synthesis intermediates

Synthetic advanced grease:

React with lithium soap/complex aluminum-based thickener to prepare high and low temperature resistant grease (-40℃~180℃).

Preparation of environmentally friendly coating film-forming agent:

After hydrolysis to sebacic acid, it synthesizes water-based polyester resin, which is used for automotive primer (enhanced adhesion and salt spray resistance).

Bis(2-ethylhexyl) sebacate CAS 122-62-3 safety

Explosive Hazard Characteristics: Can react with oxidants. Flammable Hazard Characteristics: It is more flammable when exposed to open flames, high temperatures, and strong oxidants; Combustion emissions stimulate smoke. Storage and transportation characteristics: Complete packaging, light loading and handling; Warehouse ventilation, away from open flames, high temperatures, and stored separately from oxidants.
