  • Applications

    Pentanedioic acid, 1,5-diisodecyl ester (CAS number: 29733-18-4) is commonly used as a non-phthalate plasticizer and processing additive for polymers such as PVC and other thermoplastics, improving flexibility and low-temperature performance. It also serves as a lubricating processing aid during compounding and extrusion, reducing friction and heat buildup. In coatings and inks, it functions as a plasticizer and flow modifier, promoting film formation and adhesion. It is used in adhesive formulations as a flexibilizer and tack enhancer, and may be employed as an emollient or solvent in cosmetic/personal care formulations where a long-chain ester is suitable. It can also act as a chemical intermediate in the synthesis of specialty lubricants or polymer modifiers. Subject to local regulations and formulation limits.
