Arlon 85HP’s unique blend of pure polyimide resin and micro-fi ne proprietary fi llers results in superior performance for demanding applications. Compared to conventional polyimide systems, 85HP has a lower Z-axis expansion and twice the thermal conductivity. 85HP reduces resin cracking and wicking in designs with high density plated through holes and vias. 85HP prepreg has resin fl ow characteristics and pressed thickness matching standard polyimides.
