Liquid; [MSDSonline]
Index of refraction = 1.4867 at 20 °C/D
Phthalate esters would be expected to have UV maxima in the 230 nm and 270 nm regions. /Phthalate esters/
The lower esters are colorless, mobile, and highly volatile liquids that usually have pleasant odors. As the molecular mass increases, volatility decreases and the consistency becomes waxy, then solid, and eventually even brittle, often with formation of lustrous crystals. /Esters, organic/
... Resistance to migration from polymers, low temperature flexibility ... compatibility with polar polymers and additives over a wide range of compositions. /Phthalate esters/
