Plasticizer blends comprise a triblend of diethylene glycol dibenzoate, dipropylene glycol dibenzoate, and 1,2-propylene glycol dibenzoate, in specified ratios, useful in combination with a multitude of thermoplastic polymers, thermosetting polymers, and elastomeric polymers and numerous applications, including but not limited to plastisols, adhesives, sealants, caulks, architectural coatings, industrial coatings, OEM coatings, inks, overprint varnishes, polishes, and the like. The advantages rendered by the use of the triblend depend on the type of polymer and application in which it is utilized and include among other advantages higher solvating power and lower processing time, low VOC's, reduced plasticizer freeze point, improved gelation and fusion characteristics, higher tensile strength, superior stain and extraction resistance, and improved rheology over traditional diblends of diethylene glycol dibenzoate and dipropylene glycol dibenzoate. |

1. A plastisol composition, comprising:
a. a polymeric dispersion; and b. a non-phthalate, high solvating plasticizer triblend comprising diethylene glycol dibenzoate present in an amount of at least about 60 wt. %, dipropylene glycol dibenzoate present in an amount of at least about 15 wt. %, and 1,2-propylene glycol dibenzoate present in an amount of at least about 20 wt. %, based upon the total weight of the triblend, wherein the processing viscosity of the plastisol composition is better than expected when compared to the viscosities of its components and at least comparable to that achieved with traditional dibenzoate diblends, and wherein the plastisol has superior stain resistance as compared to phthalate plasticizers. |
