Fluorosilicone rubber (FVMQ) falls into a unique class of silicone polymers that add enhanced chemical resistance to the excellent temperature performance characteristic of silicone rubber technology. These distinct materials can withstand long term exposure to aggressive chemicals, automotive fluids, fuels and oils and maintain their performance from temperatures as low as -65 C up to 225 C or higher. Their wide use temperature range and enhanced chemical resistance make them ideal materials of choice in Automotive, Aerospace, Industrial and Chemical Processing applications where extreme temperatures and chemical resistance are required. Recent advances in fluorosilicone rubber technology have led to the development of two new fluorosilicone bases, LS-4940 and LS-4960. These bases result in compounds delivering higher fuel and temperature resistance while exhibiting better handling and process. Development efforts also focused on balancing improved temperature performance with resistance to acid gas media. While these bases were specifically developed for use in turbocharger hose applications due to their improved temperature and fluid resistance, they are also finding broader use in applications beyond turbocharger hoses and their balance of properties make them good candidates for a variety of applications. This paper will present an overview of recent fluorosilicone rubber technology improvements, review the new base technology available for improved high temperature performance and better chemical resistance, and review the new fluorosilicone compound technology which can enable new sealing solutions for advanced transmission applications.
