Very soft thermal gap filler pads
Fujipoly's Sarcon PG25A is said to be one of the company’s softest and best performing thermal gap filler pads for applications that have delicate components and high compression rates. When it is sandwiched between components of varying shapes and sizes and a nearby heat sink or spreader, this compliant 2.5 W/m°K material exhibits a thermal resistance as low as 0.42°Cin2/W at 14 PSI.
This formulation is claimed to be great for applications that require material compression between 30% and 50%. Sarcon PG25A is available in four thicknesses ranging from 1 to 5mm with a maximum sheet dimension of 300mm x 200mm. Sarcon PG25A can also be ordered in die-cut form to fit almost any application shape. Fujipoly’s new material is well-suited for environments with operating temperatures that range from -40 to +150°C and exhibits a UL94 flame retardant rating of V-0.
