THERM-A-GAP 1641 | Parker Chomerics

    therm-a-form-1641

    Parker Chomerics THERM-A-FORM™ 1641 is a one-component, RTV silicone elastomer with high operating temperature range and 0.9 W/m-k thermal conducti

    THERM-A-FORM™ thermally conductive silicone elastomer products are dispensable form-in-place compounds designed for heat transfer without excessive compressive force in electronics cooling applications. These versatile liquid reactive materials can be dispensed and then cured into complex geometries for cooling of multi-height components on a PCB without the expense of a molded sheet. Each compound is available in ready-to-use cartridge systems, eliminating weighing, mixing, and degassing procedures.
