In the pursuit of extreme material performance, fluorosilicone rubber is reshaping industry perceptions with its revolutionary advantages. As a cutting-edge fusion of fluororubber (FKM) and silicone rubber (VMQ), it perfectly inherits the core advantages of both, becoming the ultimate solution for extreme working conditions.

Pushing the Limits, Unlimited Performance
Fluorosilicone rubber offers impressive temperature resistance: it maintains its elasticity down to -60°C, with some special formulations extending this to -80°C. At high temperatures, it can withstand temperatures of 200°C for extended periods, with short-term temperatures exceeding 250°C. This ultra-wide temperature range makes it suitable for applications ranging from polar research equipment to high-temperature engine systems. Its chemical resistance is also exceptional, with its molecular barrier impervious to oily media like fuel and hydraulic oil, as well as strong acids, bases, and polar solvents like acetone and toluene. While resistance may pose a challenge with certain fluorinated solvents, this underscores its reliability in a wide range of chemical environments.

Excellent performance in both static and dynamic applications
In terms of mechanical properties, fluorosilicone rubber exhibits high tensile strength and excellent resilience, with a dynamic fatigue life far exceeding that of conventional materials, making it particularly suitable for sealing applications involving high-frequency movement. Its low compression set ensures that it maintains sealing integrity even under prolonged pressure, providing long-term protection for equipment. Furthermore, its low smoke and low toxicity properties meet safety standards, and its resistance to UV and ozone degradation provides excellent weather resistance, ensuring stable performance even in the harshest environments.

Cross-industry applications define industry heights. From the automotive industry to aerospace, from chemical energy to cutting-edge medical technology, fluorosilicone rubber is ubiquitous. Turbocharger pipes, fuel system seals, rocket fuel lines, nuclear power plant valves—all of these fields, with their demanding material performance requirements, have become a platform for its value. High-temperature tubing in medical devices and high-temperature connectors in electronic and electrical applications all rely on its unique advantages to push performance boundaries.

Comparison highlights advantages, cost demonstrates value.

Compared to fluororubber (FKM), fluorosilicone rubber offers superior low-temperature elasticity and processing flexibility, while its chemical resistance is superior to silicone rubber (VMQ). Although slightly more expensive than standard rubber, its comprehensive performance benefits, resulting in extended equipment life and improved reliability, more than offset the initial investment. The only challenge to consider is vapor barrier performance, but permeability to specific gases like hydrogen can be addressed through targeted formulation optimization.

Ingenious processing creates quality products.
Fluorosilicone rubber can be molded through compression, extrusion, and injection molding. Despite its lower fluidity, complex structures can be easily achieved through optimized mold design. Platinum or peroxide compounds are recommended as curing systems, and chlorine-containing accelerators should be avoided to ensure stable performance. It is recommended to store away from high temperatures and humidity to prevent moisture absorption that may affect the final quality.
