    What is the FVMQ Rubber ?

    FVMQ rubber, known as Fluorosilicone Rubber, is a high-performance synthetic rubber that combines the properties of fluoroelastomers and silicone rubber.FVMQ rubber is made by copolymerization of fluorinated silicone monomers, and it has good resistance to oils, heat, and a certain degree of chemical resistance.

    Chemical structure and synthesis

    Monomer: The main monomers of FVMQ rubber include fluorine-containing siloxane monomers, such as fluorine-containing methyl siloxane, fluorine-containing ethyl siloxane and so on.

    Polymerization method: The synthesis of FVMQ rubber usually adopts the solution polymerization method. During the polymerization process, monomers are polymerized in organic solvents to form high molecular weight polymers.

    Polymerization initiator: Commonly used polymerization initiators include peroxides, azo compounds and so on.

    Our CBD Seals FVMQ Compounds information：

    Oil resistance: FVMQ rubber has good oil resistance and can resist petroleum-based oils, lubricants and fuels.

    Heat resistance: FVMQ rubber maintains good performance at high temperatures (usually up to 180°C or more).

    Chemical resistance: FVMQ rubber has a certain degree of chemical resistance, able to resist the erosion of some acids, alkalis and solvents, but not as extreme as pure fluoroelastomer.

    Weather resistance: FVMQ rubber has good UV and ozone resistance.

    Mechanical properties: FVMQ rubber has good tensile strength, tear strength and abrasion resistance.

    Electrical insulation: FVMQ rubber has good electrical insulation properties and is suitable for use as seals in the electrical and electronics industries.

    Processing and vulcanization

    Processing method: FVMQ rubber can be processed by traditional rubber processing methods such as extrusion, calendering, injection molding, and molding. Due to its high viscosity and high melting point, processing is difficult and requires special equipment and technology.

    Vulcanization: Vulcanization of FVMQ rubber usually uses peroxide as the vulcanizing agent. During the vulcanization process, the free radicals generated by the decomposition of peroxide react with the rubber molecular chains to form a cross-linked network.

    Areas of application

    Automotive industry: used to manufacture oil and heat resistant automotive seals, hoses, belts, etc.

    Petrochemical industry: used to manufacture chemical-resistant seals, gaskets, etc.

    Aerospace: used to manufacture high temperature and chemical resistant aerospace seals.

    Semiconductor industry: for the manufacture of chemical-resistant, high-temperature-resistant seals for semiconductor manufacturing equipment.

    Medical industry: for the manufacture of chemical-resistant, non-toxic medical equipment seals.

    Sustainability

    Recycling: FVMQ rubber can be recycled and reused to reduce the impact on the environment. Some advanced recycling technologies can convert waste FVMQ rubber into new rubber products or other useful materials.

    FVMQ rubber excels in a wide range of industrial applications with its good resistance to high and low temperatures, weathering and chemicals, as well as good electrical insulation and mechanical properties, and good processability.

    FVMQ rubber outperforms traditional fluoroelastomers in terms of high temperature resistance, low temperature resistance and weatherability, but not in terms of chemical resistance and cost.

    FVMQ rubber is superior to silicone in terms of high temperature resistance, chemical resistance and weatherability, but inferior to silicone in terms of cost and some processability.
