Material Notes:

Made from flexible graphite, eGRAFÂ® SPREADERSHIELDâ„¢ products function as both a passive heat spreader and heat shield. SPREADERSHIELDâ„¢ material can be die-cut, press-formed, or laminated with plastics, metals, adhesives, and other materials. Every SPREADERSHIELDâ„¢ part is customized to meet specific application needs and improve thermal performance within a limited space and weight. SPREADERSHIELDâ„¢ products have provided thermal solutions in a variety of industries and applications, including displays (PDP, LCD CCFL, LED BLU, OLED), cell phones, laptop and ruggedized computers, handheld gaming devices, batteries, projectors, set-top boxes, and automotive electronics. Each application is specialized to require different characteristics of SPREADERSHIELDâ„¢ products. Grade SS400 is designed specifically for large displays, notebook PCs, and handsets.
