  • Applications

    Chemical name: Diisocetyl Dodecanedioate, CAS number: 131252-83-0, is commonly used as a non-phthalate plasticizer for a range of polymers, notably PVC and polyurethane systems, to impart flexibility and reduce hardness with low volatility. It also serves as a processing aid and lubricant during industrial manufacturing, improving mixing, extrusion, and film formation. In coatings and inks, it functions as a plasticizer/flow modifier that enhances flexibility and workability. In cosmetics and personal care formulations, it can act as an emollient and solvent, contributing to skin feel and formulation performance. In electronics and related adhesive or encapsulation applications, it may be used as a plasticizer or compatibility agent to improve film properties and durability, subject to local regulations and formulation limits.
