Chemical Properties & Typical Applications
Colourless,transparent oily liquid,b.p.280℃,freezing point -65～-80℃,viscosity 8 c.p.（20℃）,refractive index 1.444（25℃）.
Used as an interior plasticizer,may be copolymerized with monomers like vinyl chloride, vinyl acetate,styrene,etc. These copolymers are usually used in preparing coatings,films,adhesives,rubbers and fixing agent for pigments. When it used for the PVC ware,it can make ware soft,lucency,high transparence.
