New data reveals you can improve vinyl baby pants while you cut costs.
Trimellitates [monomerics made with AMOCO® Trimellitic Anhydride] have always been recognized as outstanding plasticizers for baby pants. They hold up against hot soapy water. And even the heat of automatic dryers. But until now, everyone generally believed trimellitates were too expensive. Not so. And the proof is in this table. Two trimellitates [TOTM—Trioctyl, and NHTM—Tri-n-hexyl] are compared to two typically used commercially available polymeries. [The ingredients and parts of the test formulation are: Vinyl Resin/100; DIDP/25;Test Plasticizer/as indicated; EpoxyTallate Plasticizer/3; Liquid Stabilizer/4; Stearic Acid/0.5.] TOTM
