Characters and uses: This product is a colorless transparent micro *** oily liquid with a slight aroma and boiling point of 283.7 C. It can be miscible with general organic solvents such as ethanol and *** and insoluble in water and petroleum ether. This product is a kind of plasticizer with strong solubility to many kinds of resins. It can be compatible with many kinds of cellulose resins, rubber and vinyl resins. It has good film-forming, adhesion and waterproofing properties. It is often used in the manufacture of cellulose acetate film, transparent paper and moulding powder with diethyl phthalate. It is also a solvent in the manufacture of insulating paint and varnish. A small amount is used in the production of nitrocellulose. It can also be used as a plasticizer for NBR. Mixing with other plasticizers can overcome the shortcomings of high volatility and low temperature crystallization. It can also be used as a solvent for mosquito repellent oil (crude oil), polyvinyl fluoride paint, methyl ethyl ketone peroxide and DDT. Solvent for toy chemiluminescent rod (fluorescent rod).
Packaging and storage: net content 200 kg/drum, white iron or plastic-coated iron drum. This product should be stored in indoor ventilation and drying place to avoid fire source, and should be protected from violent impact during transportation.
