What are the material characteristics of powder foam and silicone outer electronic conductive strips?

In the display manufacturing process(Especially during the design process of COB module), powder foam and silicone outer electronic conductive strips (zebra strips) are two commonly used types. The properties of these two materials are different. The following table clearly summarizes the two types from multiple dimensions. Material properties.
