In the precise world of industrial manufacturing, the performance of rubber materials directly determines the stability and lifespan of end products. Ordinary rubber often falls short when faced with multiple challenges, including alternating high and low temperatures, oil corrosion, and mechanical wear. However, the emergence of high-resilience fluorosilicone compounds, combining the advantages of fluororubber and silicone rubber, has become a key material for solving the problems of harsh operating conditions.
The core competitiveness of fluorosilicone compound lies in its unique composition design. It uses fluorosilicone polymers as the base rubber, combined with reinforcing agents, antioxidants, and other additives through precise mixing. This process inherits the excellent oil, solvent, and chemical resistance of fluororubber while maintaining the outstanding high and low temperature resistance and flexibility of silicone rubber, achieving a performance breakthrough where "1+1>2". Compared to traditional silicone rubber, its oil and solvent resistance is significantly improved; compared to fluororubber, it has superior cold resistance and compression set, and its tensile strength retention is more stable at high temperatures.
Its wide temperature adaptability is a significant highlight, allowing it to operate stably within a range of -60℃ to 200℃, and even withstand short-term high temperatures of 230℃. It does not become brittle even in extremely cold environments, nor does it easily deform or age at high temperatures. This full-temperature stability enables it to handle extreme conditions in aerospace, automotive, and other industries, preventing material failure due to temperature fluctuations. Simultaneously, it possesses high mechanical strength and resilience, with different grades offering hardness ranging from Shore A20 to 90, tensile strength up to 11MPa, and excellent tear resistance, capable of withstanding long-term mechanical vibration and pressure impacts.
Its dual advantages of oil resistance and dielectric properties make it stand out in specialized fields. When exposed to various oily media such as engine oil, fuel, and transformer oil, it maintains an extremely low volume change rate. After immersion for 168 hours, the volume change remains within a reasonable range. Its low reactivity with transformer oil extends its sealing life by three times compared to ordinary materials. Furthermore, its low transformer oil dielectric loss and excellent insulation properties provide safety assurance for electrical equipment. It boasts an ozone aging resistance rating of 5, enabling an ultra-long service life of 15 years, and effectively resists environmental corrosion from humidity, heat, and ultraviolet radiation.
Its ease of processing makes it highly favored in industrial production. After being refining on an open mill and adding a vulcanizing agent, it can be adapted to various molding processes such as compression molding, injection molding, and extrusion. The standardized process of single-stage and two-stage vulcanization allows for precise control of product performance, reducing processing losses and lowering production costs. Low-hardness products can be produced without the addition of plasticizers, further expanding the flexibility of product design and meeting the customized needs of different scenarios.
From aircraft fuel system seals and integral fuel tank gaskets in the aerospace industry, to engine oil pan gaskets and fuel pump diaphragms in the automotive industry, to corrosion-resistant valve seals in the petrochemical industry and transformer sealing components in the power industry, high-resilience fluorosilicone compound has penetrated into many core aspects of high-end manufacturing. In the medical and health field, it can also be used in medical catheters, artificial valves, and other devices, ensuring safe use due to its environmentally friendly and low-permeability properties.
