Dioctyl adipate is an excellent cold resistant plasticizer for polyvinyl chloride, which endows products with excellent low tenderness and smoothness, as well as certain light, thermal stability, and water resistance. The pressed and rolled products of dioctyl adipate exhibit excellent lubrication performance during production, and the product has a good hand feel. In plastisols, the initial viscosity is low and the viscosity stability is good.

DOA is usually used in conjunction with plasticizers such as DOP in cold resistant agricultural films, wires, artificial leather, outdoor water pipes, and packaging films for frozen food. DOA can also be used as a low-temperature plasticizer for many rubbers, as well as a plasticizer for resins such as nitrocellulose and ethyl cellulose.

Dioctyl adipate is a typical cold resistant industrial plasticizer with high growth efficiency and is widely used in industries such as sheet metal and synthetic leather. Have you ever understood its working principle? Today, let's introduce it to everyone.

1) When dioctyl adipate is melted with resin, small molecules of the plasticizer's action principle will be inserted between polymer molecular chains, weakening the attraction between polymer molecular chains. The action principle of the plasticizer increases the distance between them, resulting in an increase in the possibility of polymer molecular chain movement, a decrease in entanglement between polymer molecular chains, and a glass transition of the resin at lower temperatures, This increases the plasticity of the plastic.
From this, it can be seen that the principle of action of dioctyl adipate is due to the attraction and entanglement between polymer molecular chains, which is a major reason for the anti plasticization effect.

2) The molecular structure of polymers also affects the attraction between polymer chains, especially the properties of the functional groups on the polymer chains. Molecular chains with strong polar groups have high intermolecular forces, while those with non polar groups have low intermolecular forces. In order to make polymers with strong polar groups easy to form, plasticizers can be added. The polar group of dioctyl adipate will interact with the polar group of the polymer, This weakens the gravitational force between polymers, thus achieving the goal of plasticization.

As a plasticizer, Dioctyl adipate is mainly used for polyvinyl chloride, vinyl chloride copolymers, nitrocellulose, ethyl cellulose, and synthetic rubber. It is particularly suitable for making cold resistant wire and cable materials, artificial leather, films, sheets, and other products. As a low-temperature plasticizer for various synthetic rubbers, Dioctyl adipate has no effect on rubber vulcanization.
