Product Description Product ParametersProduct Category: SS series Product Overview SS series are natural graphite products. A variety of in-plane thermal conductivity options from 300 to 600 W/m·K and through-plane thermal conductivity from 2.8 to 4.1 W/m·K. A broad range of thicknesses from 0.040mm to 0.94m. SS series are a unique line of products capable of cooling a hot component, protecting a temperature-sensitive component, reducing a thermal gradient, or preventing a surface hot spot. Product Application SS series products are ideal for all kinds of range of electronics applications, including smartphones, tablets, displays, set-top boxes, enclosed electronics, and medical devices, transportation and aerospace application.
