DOA is more volatile, and has certain deficiencies in water resistance, mobility, and electrical insulation.
The United States, France, Italy, Japan, the Netherlands and other countries have approved this product for use in food packaging materials.
Relative molecular mass: 371
Application Guide:
1. As a typical cold-resistant plasticizer, DOA has high growth efficiency and little discoloration due to heat. It is suitable for various resins such as polyvinyl chloride, vinyl chloride copolymer, polystyrene and synthetic rubber.
2. It can give the product good low temperature flexibility and light resistance, and the product feels good.
3. Mainly used with DOP, DBP and other main plasticizers and used in cold-resistant agricultural films, frozen food packaging films, wire and cable coatings, artificial leather, plates, outdoor water pipes, etc.
4. When used for plasticizing paste, the initial viscosity of the paste is low and the viscosity stability is good.
