3. Application: DOA is a typical cold-resistance plasticizer with high plastifying efficiency and no thermochromatic effect. It has been applied widely to the resins such as PVC, vinyl chloride co-polymers, PS and synthetic rubber.
It has been applied with DOP and DBP in cold-resistance agricultural thin membrane, frozen food packaging film, wire and cable coating layer, artificial leather, panel, etc. It has been used as the thickener to achieve the low viscosity and good stability of the product.
