Perfluoropolyether is also used in the field of medical devices, such as artificial joint lubricants, pacemakers, etc.It has good biocompatibility, will not cause adverse reactions to the human body, and can provide long-term lubrication and stability.
Surface coating：
The low surface tension and excellent chemical stability of perfluoropolyether make it an ideal surface coating material.It can form a uniform and smooth coating on metal, glass, plastic and other surfaces to improve the corrosion resistance and wear resistance of the surface.
Aerospace：
In the aerospace field, perfluoropolyethers are used in the manufacture of high-temperature and corrosion-resistant sealing materials and lubricants.It can withstand extreme temperature and pressure conditions to ensure the normal operation of aerospace equipment.
