Description

Dimethyl Perfluoroazelate is a high-performance fluorinated diester, a key intermediate in the synthesis of advanced materials. Its fully fluorinated carbon chain imparts exceptional chemical resistance, thermal stability, and low surface energy properties. This compound is essential for manufacturers in the specialty polymer, surface treatment, and high-performance lubricant industries seeking to enhance product durability and performance under extreme conditions.

Application

• Fluoropolymer Synthesis: A critical monomer for producing high-performance fluorinated polyesters and polyurethanes with enhanced chemical and thermal resistance.
• Specialty Lubricants & Greases: Used as a base fluid or additive to formulate lubricants for extreme environments (high temperature, corrosive atmospheres).
• Surface Modifiers & Coatings: Imparts oil, water, and stain repellency to textiles, leather, paper, and non-woven fabrics.
• Release Agents & Mold Lubricants: Provides excellent non-stick properties in industrial molding processes for plastics, rubber, and composites.
• Fire-Fighting Foams (Historical/Formulative): Serves as a precursor or component in the development of fluorosurfactants for aqueous film-forming foams (AFFF).
• Electronic & Electrical Materials: Used in the formulation of dielectric fluids, heat transfer fluids, and protective coatings for sensitive components.

Quality Control

Our Dimethyl Perfluoroazelate is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR), to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key physical properties are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and organic solvents. Recommended storage temperature is between 15°C and 25°C. The container must be kept tightly sealed to prevent moisture absorption and contamination.
