K-FLEX PG (propylene glycol dibenzoate) is a grade of dibenzoate designed primarily for use in PVC compositions. K-FLEX PG is a very high solvator for vinyl so it is particularly useful in blends of plasticizers to allow the tailoring of performance characteristics. K-FLEX PG imparts outstanding stain resistance in vinyl compositions as well as excellent durability properties.
