DOA Eco-friendly Plasticizer can be used together with DOP and DBP in cold-resisting agricultural plastic film, freezing food, packing film, cable, electric wire, imitation paper, planet, outdoor water pipe. 
While DOA Eco-friendly Plasticizer is used in, initial viscosity is low and stable. 

However, DOA Eco-friendly Plasticizer should be used with care for it has high volatility, and is poor in water-proof, migratory aptitude property and electric insulating property.
DOA is an organic compound with the formula (CH2CH2CO2C8H17)2. 

As well as related diesters derived from 2-ethylhexanol, decanol, isodecanol, etc., DOA is used as a plasticizer.
DOA, also known as DOA, is a light colored, oily liquid. 

DOA is flexible at low temperatures, has good electrical properties, good resistance to weathering, and good stability to heat. 
DOA, or DOA, is an oily liquid that is most frequently used as a plasticizer for PVC. 

DOA’s light in color and may be used in combination with other plasticizers or by itself. 
DOA is soluble in oil but not water. 

Because of DOAs low cost, suitable properties and manufacturing by many companies, DOA goes by many names, including bis (2-ethylhexyl) phthalate and adipic acid di(2-ethylhexyl) ester.
DOA is most commonly used as a plasticizer thanks to its extreme flexibility, low temperature and good electrical properties. 

DOA also has a strong resistance to weathering and good heat stability. 
There are many uses for DOA, but you’re most likely to find it being used as clear films for food packaging.

DOA is an effective plasticizer that provides the utmost flexibility and stability at low temperatures. 
In DOAs solid state, the organic compound is a clear liquid that can be easily added to other plasticizers such as DOP and DOTP. 

DOA’s also compatible with nitrocellulose, ethyl cellulose, high-butyryl cellulose acetate butyrates and most synthetic rubbers.
DOA is a clear, almost colourless liquid with a barely noticeable odour. 

DOA is an ester produced by reacting adipic acid with 2-ethyl hexanol. 
DOA has low viscosity, is easy to process and has a long shelf life.

DOA 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.
DOA is a colorless, odorless, transparent oily liquid that is mostly used as a PVC plasticizer. 

DOA is compatible with a wide variety of materials such as nitrocellulose, ethyl cellulose, most synthetic rubbers, cellulose acetate butyrate, PVC, chloroethylene polymer and cellulose nitrate. 
DOA can be used alone or with other plasticizers such as Dioctyl Phthalate (DOP) and Dibutyl Phthalate (DBP), cold resistant agricultural plastic film, freezer food, packaging film, cable, electrical wire, and more.
DOA can also be used as a Group V Synthetic base oil, especially in applications where low temperature performance is required, and can be mixed with Group III and Group IV base oils to improve its properties.

USES OF DOA:
The product is an excellent cold resistant plasticizer of PVC, which gives the product excellent low softness, light thermal stability and water resistance. 
In the plastisol, the initial viscosity is low and the viscosity stability is good. 

DOA is often used with DOP and other main plasticizers for cold resistant agricultural film, wire, sheet, artificial leather, outdoor water pipe and packaging film of frozen food.
DOA can also be used as a low temperature plasticizer for many synthetic rubbers and for resins such as nitrocellulose and ethyl cellulose. 

DOA can be used as a cold resistant plasticizer for a variety of resins, especially PVC and vinyl chloride copolymers. 
DOA can also be used as the raw material of aviation grease. 

DOA can be used as stationary liquid for gas chromatography (the highest operating temperature is 135 ℃, and the solvent is ether).
DOA is used alone or together with other plasticizers as a softener in all PVC paste and dough mixtures. 

DOA is used in the production of Stretch Film, in the production of phthalate-free goods (in the toy industry, in the production of skin cloth, in the production of some special hoses, in the production of tablecloths, etc.), in the production of artificial leather, in the production of cables, in the production of PVC mats, in the production of tarpaulin.
DOA is a versatile compound that has many uses. Here are some of the applications that you can find DOA in.

DOA can be used on cold resistant agricultural plastic film, freezer food, packaging film, cable, electrical wire, imitation paper, planet and outer water pipe. 
DOA provides good low temperature flexibility, good heat stability, weatherability properties, high plasticizing efficiency and good electrical properties, making it particularly suitable for use in flexible coatings and PVC colorants.

DOA can be used in food contact applications such as food packaging films and sealants as well as to disperse pigments in paint. 
DOA can be found in many commercial products such as shoes, slippers, synthetic leather, door mats, and more.
