    What is the Aflas FEPM Rubber ?

    Aflas rubber is a special type of fluoroelastomer, Aflas being the abbreviation for “Asahi Fluoro Rubber”, and is characterized by its combination of a copolymer of tetrafluoroethylene (TFE) and propylene, as well as a certain percentage of a sulfur vulcanization system. sulfur vulcanization system. This unique combination gives Aflas rubber some unique properties.

    What is the Aflas FEPM Rubber ?

    Monomers: The primary monomers of Aflas rubber are tetrafluoroethylene (TFE) and propylene.

    Polymerization method: Aflas rubber is usually synthesized by solution polymerization. During the polymerization process, monomers are polymerized in an organic solvent to form a high molecular weight polymer.

    Polymerization initiators: Commonly used polymerization initiators include peroxides, azo compounds, etc.

    Our CBD Seals FEPM Compounds information：

    Chemical resistance: Aflas rubber has excellent chemical resistance and can resist most acids, alkalis, solvents and oxidizers.

    Heat resistance: Aflas rubber maintains good performance at high temperatures (usually up to 175°C or more).

    Oil and Fuel Resistance: Aflas rubber has good resistance to petroleum-based oils, lubricants and fuels.

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

    Mechanical Properties: Aflas rubber has good tensile strength, tear strength and abrasion resistance.

    Sulfur Vulcanization: A distinctive feature of Aflas rubber is that it can be vulcanized by a sulfur vulcanization system, which is different from the peroxide vulcanization system used in most other fluoroelastomers. Sulfur vulcanization makes Aflas rubber more cost-effective and easier to process in some applications.

    Processing and vulcanization

    Processing Methods: Aflas rubber can be processed by extrusion, calendering, injection molding, molding and other traditional rubber processing methods. Due to its high viscosity and high melting point, processing is difficult and requires special equipment and techniques.

    Vulcanization: Vulcanization of Aflas rubber usually uses sulfur and accelerators as vulcanizing agents. During sulfur vulcanization, sulfur reacts 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: Aflas rubber can be recycled and reused to reduce the impact on the environment. Some advanced recycling technologies can convert waste Aflas rubber into new rubber products or other useful materials.

    With its unique chemical resistance, high temperature resistance and improved low temperature performance, Aflas rubber meets the needs of a wide range of industrial applications while being cost effective.

    Aflas rubber outperforms traditional fluoroelastomers in low-temperature performance and processability while being less costly, but may be slightly less effective in extreme chemical resistance and high-temperature performance.

    Aflas rubber is superior to NBR in terms of chemical resistance, high temperature resistance and low temperature performance, but less so in terms of cost and certain mechanical properties.
