MEET THE FUTURE- READY LUBRICANTS Perfluoropolyether (PFPE) lubricants are a class of synthetic lubricants originally developed for military and aerospace use. Their long- chain polymer structure confers on them excellent thermal and chemical stability, low volatility, and unmatched lubricity, even at extreme temperatures. PFPEs provide excellent lubrication within a wider temperature range (from -70°C to more than 300°C) than most other lubricant types. PFPE lubricants’ unique chemistry

properties. As a lightweight sealant and insulator, dielectric grease has long been a crucial tool for protecting vehicles’ electric connections against corrosion and heat/water damage. It also reduces the amount of force and friction required to mate electrical connections, increasing their strength and longevity. These qualities are essential in ICEs, and even more so
also makes them inert, which helps them protect and maintain mechanical performance even in the presence of highly reactive chemicals. In many cases, warranties on critical vehicle engine parts and structural parts can be extended thanks to the durability of these lubricants. Another cost-saving factor of PFPEs is their “once-and-done” benefit. Less product is required, and performance is long-lasting, eliminating the need for relubrication. Moreover, PFPE lubricants exhibit excellent compatibility with a variety of plastics and elastomers. They are nonflammable and have low toxicity. PFPE lubricants provide numerous
benefits in a variety of automotive applications, including extreme temperature performance. PFPE
The benefits of PFPE lubricants explained
lubricants maintain their lubricity from -73°C to greater than 360°C (-99°F to 680°F), depending upon operating conditions and product grade. Regarding inertness, PFPE lubricants won’t harm painted surfaces, plastics, or elastomers. They are compatible with nearly every material they might contact and resist migration. Additionally, PFPE lubricants offer
chemical stability, withstanding exposure to fuels, coolants, brake fluid, engine oil, washer solvent, and even battery acid for dependable long- term performance. PFPE lubricants also deliver outstanding dielectric properties, due to the fact they are excellent insulators and have become the lubricant of choice for many automotive electrical applications.
THE ONE CONSTANT Whatever the changes ahead for automotive technology, one constant remains: the importance of premium lubricants for delivering the performance and reliability OEMs stake their reputations on. The right choice in lubricants can help maintain the expected levels of safety, efficiency, reliability, and comfort in advanced auto designs—both today and for the road ahead.
