Description
Dioctyl azelate (DOA, CAS 103-24-2) is a diester plasticizer derived from azelaic acid and 2-ethylhexanol, supplied under trade names including Truflex DOX, Staflex DOX, and Plastolein 9058. It carries no assigned E-code and is identified under EC 203-091-7 with HS code 29171390.
In PVC and synthetic rubber compounding, dioctyl azelate functions as a primary plasticizer, lowering the glass transition temperature to maintain flexibility at low service temperatures, making it suitable for cable sheathing and cold-weather seals. It also serves as a synthetic base fluid and lubricity additive in metalworking formulations, where its ester structure reduces friction between metal surfaces under moderate load conditions.
Dioctyl azelate is supplied in liquid form and is subject to REACH registration requirements for EU market supply. Procurement quantities are typically available in drums and IBC containers. Buyers should confirm grade specification and purity documentation directly with the supplier prior to order placement.
