| Application | This product is an excellent cold-resistant plasticizer for polyvinyl chloride, which endows the product with excellent low-temperature flexibility, and has a certain photothermal stability and water resistance. In the plastisol, the initial viscosity is low and the viscosity stability is good. It is often used with main plasticizers such as DOP for cold-resistant agricultural films, electric wires, thin plates, artificial leather, outdoor water pipes and packaging films for frozen foods. It can also be used as a low temperature plasticizer for many synthetic rubbers and a plasticizer for resins such as nitrocellulose and ethyl cellulose. It is used as a stationary liquid for gas chromatography in laboratory work. The toxicity of di (2-ethylhexyl) adipate is very low, the lethal dose to humans is about 500000mg/kg, and the LD50 of oral administration to rats is 3000-6000mg/kg, and the irritation to skin and eyes is also slight. The cold-resistant plasticizer used as a variety of resins, especially polyvinyl chloride and Vinyl Chloride Copolymer, can also be used as a raw material for aviation Grease gas chromatography stationary liquid (maximum use temperature 135 ° C., solvent ether). Plasticizers. Solvent. |
