Dioctyl adipate (DOA) is a clear, almost colourless liquid with a barely noticeable odour. It is miscible with most organic solvents and compatible with other monomeric plasticizers used in PVC but it is not soluble in water. DOA is an ester produced by reacting adipic acid with 2-ethyl hexanol. It has low viscosity, is easy to process and has a long shelf life.
It has several advantages over some other plasticizers in that it is more economical; it provides the desired changes to physical and mechanical properties without causing changes to the chemical structure of the polymer; it jellifies quickly; in lacquer applications it serves to eliminate cracks, increase resistance and provide a smooth surface.
Synonyms: Adiimoll DO; Dioctyladipat; Dicaprylyl adipate; Adipic acid dioctyl; Dioctyl hexanedioate; Adipic Acid,Octylester; Adipic acid dioctyl ester; Hexanedioic acid dioctyl ester; Dioctyl ester of hexanedioic acid
Applications of Dioctyl Adipate Suppliers
Dioctyl adipate is used in the manufacture of a wide range of plastics and coating products. It is especially suitable for use in flexible coatings and PVC colorants and in any plasticized products which require good low temperature properties. It is used as a plasticizer in PVC paste and pulp mixtures and as an additive in many other processes.
Dioctyl adipate can be found in many end products including PVC soles for shoes and slippers, synthetic leather, waterproof membranes, paints, varnishes, floor coverings, door mats and hoses. It is also used in the calendaring process of paper finishing and in the production of PVC granules.
As dioctyl adipate meets the requirements for food-contact materials (FCM), it may also be used in the manufacture of flexible PVC films used for food packaging.
Storage and Handling
Dioctyl adipateshould be stored in tightly-closed containers below 40°C, in a well-ventilated place. The exclusion of atmospheric moisture is recommended in order to prevent deterioration of the product. In these conditions it can be stored for periods of up to one year.
This material should be handled in accordance with good industry safety and hygiene practices. Relevant engineering controls should be implemented. Personal protective equipment should be worn as deemed necessary by appropriate risk assessments.
