DOA is a typical cold-resistant plasticiser, with high growth rate efficiency, high heat plasticising efficiency and small heat discolouration, it is suitable for a variety of resins such as PVC, vinyl chloride copolymer, polystyrene and synthetic rubber. It can give the products good low-temperature softness and light resistance, and the products have better handfeeling. It is mostly used together with DOP, DBP and other main plasticisers in cold-resistant agricultural films, frozen food packaging films, wire and cable coverings, artificial leather, plates, outdoor water pipes and so on. When used in plasticising paste, the initial viscosity of the paste is low and the viscosity stability is good. The United States, France, Italy, Japan, the Netherlands and other countries have licensed this product to be used in food packaging materials.
