Diethyl Phthalate（DEP）
Properties
●Colourless,transparent oily liquid,slight aromatic odour,viscosity 13 c.p.（20℃）,refractive index 1.499～1.502（20℃）.
●Good compatibility with most of ethylenic and cellulosic resins.
Plasticizer for cellulosic resins granting a good softening and
long-lasting property at low temperature. If combined with DMP
together,it may increase the water-durability and elasticity of the
product.
