 ? Properties and Uses: colorless transparent light yellow oily liquid, slightly aromatic flavor, boiling point is 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 of plasticizer, with a variety of cellulose resins, rubber, vinyl resin compatibility, good film-forming, adhesion and water resistance. Often meet with diethyl phthalate cellulose acetate film for the transparent paper and molding powder production. Is insulating paint, varnish production of solvents. A small amount of nitro-cellulose for the production. Nitrile rubber may also be used as a plasticizer. Mixed with other plasticizers, can overcome the large and volatile disadvantages such as low temperature crystallization. This product is also used as a mosquito repellent oil (crude oil), polyvinyl fluoride coatings, methyl ethyl ketone peroxide, and DDT solvents. Toy chemical light stick (light stick) making the solvent. 

 ? Packaging and storage: Net content 200 kg / barrel, stainless steel or plastic coated metal pail. This product should be stored in dry indoor air, to avoid fire, in the transport process should prevent crashing.
