Perfluoropolyethers
Perfluoropolyethers (PFPE) are synthetic polymers that are liquids at room temperature and have unique physical and chemical properties. Lubricants have been used as lubricants for space machinery components for decades, and their physical, chemical and tribological properties have been recognized.
Perfluoropolyether is a special perfluorinated polymer compound, with an average molecular weight ranging from 500 to 15000, and only three elements in the molecule: C, F and O. It has many superior physical and chemical properties, including high temperature resistance, oxidation resistance, non-combustible, non-volatile, non-toxic, low pour point, low surface tension, excellent dielectric and lubricatability, chemical inertness and biological inertness, etc.
In terms of chemical structure, there are no carbon-hydrogen bonds in the perfluoropolyether molecule, so it has high thermal and chemical stability. In a high-temperature environment, perfluoropolyether can maintain its original physical and chemical properties, so it is widely used in various fields that require high temperature resistance.
In addition, perfluoropolyethers have the characteristics of low surface tension, low viscosity, high wettability, high permeability and high diffusion, making them widely used in various fields that require lubrication and cleaning. Due to its high dielectric constant and low dielectric loss, perfluoropolyethers are also used as protective materials for electrically insulating dielectrics and radio parts.
In general, perfluoropolyether is a special compound that has a wide range of applications in many fields. Due to its excellent physical and chemical properties, perfluoropolyether has become one of the indispensable materials in many fields.
