Description

Didodecyl Sebacate is a high-molecular-weight diester of sebacic acid and dodecyl alcohol, valued for its excellent performance as a synthetic lubricant and plasticizer. Its primary value lies in its exceptional thermal stability, low volatility, and compatibility with a wide range of polymers and elastomers. This compound is essential for manufacturers in the plastics, lubricants, and specialty chemical industries seeking reliable, high-performance additives.

Application

• Synthetic Lubricant Base Stock: Used in high-temperature lubricants, compressor oils, and aviation fluids due to its outstanding thermal and oxidative stability.
• Polymer Plasticizer: Imparts flexibility and low-temperature performance to PVC, polyurethane, and other specialty polymers.
• Functional Fluid: Serves as a component in heat transfer fluids, hydraulic fluids, and dielectric fluids.
• Elastomer Processing Aid: Acts as a processing aid and softener in synthetic rubber formulations to improve flow and mold release.
• Cosmetic & Personal Care Ingredient: Functions as an emollient and skin-conditioning agent in high-end cosmetic formulations.
• Adhesive & Sealant Formulation: Used as a plasticizer and viscosity modifier to enhance the performance of adhesives and sealants.
