Flame-Retardant and Heat-Conducting Potting Compound
InquiryFlame-retardant and heat-conducting potting compounds are specialized materials used in the encapsulation of electronic components to enhance safety and reliability. These compounds are engineered to resist ignition and slow down the spread of flames, thus providing a crucial barrier in environments where fire hazards are a concern. Additionally, their heat-conducting properties allow for efficient thermal dissipation, helping to manage the heat generated by electronic devices and preventing overheating. Our flame-retardant and thermally conductive potting compound is a two-component, condensation-curing silicone sealing material that can cure at room temperature. During the curing process, it releases ethanol molecules, which ensure that it does not corrode materials such as polycarbonate (PC), polypropylene (PP), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), polyvinyl chloride (PVC), copper wire, aluminum, tin, and other common substrates.
