Description

2,2-Dimethyl-1,3-Propanediyl Dioleate is a diester compound derived from neopentyl glycol and oleic acid, valued for its excellent stability and hydrophobic character. This chemical serves as a high-performance intermediate and functional additive, offering enhanced resistance to hydrolysis, heat, and oxidation compared to standard esters. It is primarily utilized in the formulation of advanced lubricants, plasticizers, and specialty polymers where long-term performance under demanding conditions is required.

Application

• Synthetic Lubricant Base Stock: Used as a core component in high-temperature, hydrolytically stable synthetic lubricants and compressor oils.
• Polymer Plasticizer: Acts as a secondary plasticizer in PVC and other polymer systems to improve flexibility and low-temperature performance.
• Metalworking Fluid Additive: Incorporated into formulations to provide lubrication, corrosion inhibition, and stability in water-based and neat cutting oils.
• Cosmetic & Personal Care Emollient: Functions as a non-greasy, stable skin-conditioning agent and emollient in creams and lotions.
• Co-additive for Stabilizers: Enhances the efficacy of primary stabilizers (e.g., in PVC) by improving compatibility and processability.
• Specialty Chemical Intermediate: Serves as a building block for the synthesis of more complex esters, surfactants, and functional fluids.

Quality Control

Our 2,2-Dimethyl-1,3-Propanediyl Dioleate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, acid value, hydroxyl value, and color determination, to ensure it meets precise specifications for industrial and specialty applications. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and consistent quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and oxidizing agents. For long-term storage, consider under an inert atmosphere (e.g., nitrogen) to minimize oxidation.
