Uses This product is an excellent cold plasticizer of PVC, giving products excellent low temperature flexibility, and has a certain light and heat stability and water resistance. In the plastisol, the initial viscosity is low, viscosity stability is good. Often used with DOP and other primary plasticizers and for cold-resistant agricultural films, wires, sheet, leather, outdoor water pipes and frozen food packaging film. Also can be used as many low-temperature synthetic rubber plasticizer and nitrocellulose, ethyl cellulose and other resin plasticizer. In the laboratory work for gas chromatography stationary phase. Di-2-ethylhexyl adipate is very toxic and has a lethal dose of about 500,000 mg / kg. The oral LD50 is 3000-6000 mg / kg in rats. The skin and eye irritation is also mild.
Use as a variety of resins, especially polyvinyl chloride and vinyl chloride copolymer cold plasticizer, can also be used as aviation grease raw materials
Use gas chromatography stationary phase (the maximum temperature of 135 ℃, solvent ether). Plasticizer. Solvent.
