Properties
DOP is almost colourless and odourless oily liquid, free of foreign materials
which is, slightly soluble in water( 0.285mg/L at 240c ) but soluble in alcohols, hexane etc. and is miscible and compatible with all the monomeric plasticizers of PVC
compounding.
Advantages :-
I) It is almost smell less.
Ii) Its volume resistivity is much higher than any other DOP.
Iii) It has less volatility due to less % of moisture & residual alcohol.
Application
95% of DOP is used as a Plasticizer in PVC resins for fabricating flexible vinyl Product like :- vinyl upholstery, tablecloth, shower, curtain, raincoat, shoes, garden hoses, swimming pools liners, polymeric coating, cable coating, component of paper & paperboard, defoaming agents, surface lubricants, in order of importance.
The only significant non-plasticizer use for DOP is an replacement for polychlrinated biphenyls in dielectric fuild for electric capacitors. The miscellaneous use for DOP are :- as the solvent in erasable ink, as an acaricide for use in orchards, as an inert ingredient in pesticides, as an vacuum pump oil, in detecting leaks in respirators.
Packing & Storage Shelf Life
DOP is packed in 200/225 Kg iron drum/HDPE drum, 20-22 MT in Flexi tank / ISO tank / road tanker. It is stored in tightly closed container, in a cool & dry, ventilated. Original characteristics remain intact for 24 month, if kept in recommended storage.
