Description

Perfluoropolyether CAS NO 76415-97-9 is a high-performance synthetic fluorinated fluid characterized by its exceptional chemical inertness, thermal stability, and low surface tension. This unique combination of properties makes it an indispensable material in demanding industrial and high-tech applications where conventional lubricants and fluids fail. It is primarily sought after by manufacturers in the aerospace, semiconductor, and precision engineering sectors for its reliability under extreme conditions.

Application

• High-Vacuum Lubricants & Greases: Used as a base fluid for lubricants in vacuum pumps, space mechanisms, and semiconductor fabrication equipment due to its extremely low vapor pressure.
• Electronic & Electrical Fluids: Serves as a dielectric coolant and heat transfer fluid in high-voltage transformers and advanced electronics.
• Aerospace & Defense: Employed in oxygen systems, inertial guidance systems, and as a lubricant for components exposed to aggressive fuels and oxidizers.
• Chemical Processing Industry (CPI): Acts as a non-reactive sealing and damping fluid in pumps and valves handling corrosive chemicals.
• Precision Instrument Lubrication: Ideal for fine mechanisms in analytical instruments, watches, and optical devices where long-term stability is critical.
• Release Agents & Mold Lubricants: Used in plastic, rubber, and composite manufacturing for its excellent anti-stick properties.

Quality Control

Our Perfluoropolyether is manufactured under stringent quality management systems. Each batch is subjected to rigorous analytical testing, including viscosity, density, acidity, and infrared spectroscopy for structural confirmation, to ensure it meets precise performance specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your technical requirements.

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, strong bases, and reactive metals. Ensure containers are kept tightly sealed to prevent moisture absorption and contamination.
