    What is the Silicone Rubber ?

    Silicone Rubber, known as Silicone Rubber, is a polymer material made by polymerizing siloxane monomers. Silicone rubber is known for its excellent heat and cold resistance, electrical insulation and chemical stability, and is widely used in several industries.

    Chemical structure and synthesis

    Monomer: The main monomers of VMQ rubber include methyl silicone (MeSiO), phenyl silicone (PhSiO) and so on.

    Polymerization method: VMQ rubber is usually synthesized by solution polymerization or emulsion polymerization. In the process of polymerization, siloxane monomer carries out ring-opening polymerization reaction under the action of catalyst to form high molecular weight polysiloxane.

    Polymerization catalysts: Commonly used polymerization catalysts include platinum (Pt), tin (Sn) and so on.

    Our CBD Seals VMQ Compounds information：

    Heat resistance: VMQ rubber has excellent heat resistance and can maintain good performance at high temperatures (usually up to 200°C or more).

    Cold resistance: VMQ rubber has good cold resistance and can maintain flexibility at very low temperatures.

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

    Chemical stability: VMQ rubber has good chemical resistance and can resist the erosion of some acids, alkalis and solvents.

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

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

    Physiological inertness: VMQ rubber has good physiological inertness and is suitable for use in the medical and food industries.

    Processing and vulcanization

    Processing methods: VMQ 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: VMQ rubber is usually vulcanized using a peroxide or platinum catalyst as the vulcanizing agent. During vulcanization, the vulcanizing agent reacts with the rubber molecular chains to form a cross-linked network.

    Areas of application

    Automotive industry: Used to manufacture heat-resistant and cold-resistant automotive seals, hoses, belts, etc.

    Electronic industry: used to manufacture high temperature resistant and electrically insulated electronic component seals.

    Medical industry: used to manufacture chemical-resistant, non-toxic medical equipment seals.

    Food industry: used to manufacture high temperature resistant, non-toxic food processing equipment seals.

    Aerospace: for the manufacture of high-temperature, chemical-resistant aerospace seals.

    Sustainability

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

    VMQ rubber excels in a wide range of industrial applications with its excellent high temperature resistance, low temperature resistance, weatherability and chemical stability, as well as good electrical insulation and physiological inertness.

    VMQ rubber outperforms fluoroelastomer in terms of high temperature resistance, low temperature resistance and chemical stability, but is inferior to fluoroelastomer in terms of oil resistance, mechanical properties and cost.

    VMQ rubber is superior to NBR in terms of high temperature resistance, low temperature resistance and chemical stability, but inferior to NBR in terms of oil resistance, mechanical properties and cost.
