Siloxane-free heat-conductive sheet

Electronic equipment can generate a lot of heat, and heat-conductive sheet is one way to dissipate it.

But conventional heat-dissipating sheets made of silicone have often caused problems: due to the high-volatility of the low-molecular weight siloxane contained in the material, it adhered to electrical contacts in the equipment, producing silicon dioxide, an electrical insulator. And this, of course, eventually caused defective electrical contacts in the equipment.

For that reason, Furukawa Electric has recently developed 'F-CO Sheet', a heat-conductive sheet that contains no low-molecular weight siloxane. The new sheet is made using acrylic rubber.

Standard products range in thickness from 0.09 to 4 mm, but other products are also available, including a type that uses an aluminium and carbon graphite sandwich.
