  • Applications

    Pentaerythrityl Tetraethylhexanoate (CAS 7299-99-2) is a pentaerythritol tetrakis ester used primarily as a plasticizer for PVC and other polymers, improving flexibility and processability in coatings, inks, and adhesives. It is commonly employed as a processing aid and flow modifier in resin formulations and alkyd-based coating systems. In cosmetics and personal care, it can function as an emollient and a lightweight solvent in formulations. It may also serve as a lubricant additive or viscosity modifier in industrial lubricants and grease formulations. Additionally, it can act as an intermediate in the production of specialty esters for coatings and resin products.
