 ? Properties and Uses: This product is colorless transparent light yellow oily liquid, slightly aromatic flavor, boiling point 283.7 ℃. With ethanol, ether and other common organic solvents, insoluble in water and petroleum ether. This product is a solution for a variety of resin has a very strong force in the plasticizer, with a variety of cellulose resin, rubber, vinyl resin compatibility, good film-forming, adhesion and water resistance. Often used with diethyl phthalate cellulose acetate film, transparent paper and molding powder production. Is insulating paint, varnish solvent production. A small amount of nitro-cellulose for the production. Nitrile rubber plasticizers can also be used. Mixed with other plasticizers, can overcome the large and low-temperature crystallization of volatile and other shortcomings. This product is also used as insect repellent oil (crude oil), polyvinyl fluoride coatings, methyl ethyl ketone peroxide, and DDT solvents. Toys chemical glow sticks (light sticks) making the solvent. 

 ? Packaging and storage: Net content of 200 kg / drum, tin or plastic coated metal pail. This product should be stored in a room ventilated dry place, avoid fire, in the transport process should be to prevent crashing.
