High-temperature, oil-resistant, flame-retardant sealing materials, cylinder diaphragm linings, and aerospace/aeronautic products, such as anti-static flame-retardant rubber sheets, are functional materials optimized through the selection of flame-retardant agents, anti-static agents, and fillers. They are produced through processes including blending, mixing, re-melting, calendering into sheets, and vulcanization. Their physical and mechanical properties comply with the GB5574-85 standard for rubber sheets, with a volume resistivity of 3.3×10³Ω·cm and flame-retardant performance that extinguishes immediately upon removal of the flame. This material is primarily used for manufacturing industrial components such as seals and cylinder diaphragm linings, and is also applied in aerospace and aeronautic fields.
