Stick-it Flexible is a novel sticker-type heat radiation material for dissipating heat generated from electronic equipment during operation. The Stick-it Flexible, developed by Oki with the collaboration with Ceramission Co, is quite flexible, and can be cut by scissors and stuck to even curved metallic surfaces. This product is based on the technology of heat-radiating liquid ceramic paint, which was also developed by two companies.

Oki will begin the shipment of the heat radiation sticker this month.

“The development of Stick-it Flexible and heat-radiating liquid ceramic paint are epoch-making because they can replace heatsinks, which occupy space in electronic equipment.

I believe these products match the market requirements for efficient downsizing and power-saving of electronic equipment”, said Harushige Sugimoto, President of Manufacturing Service Company at Oki Electric.

The new jointly developed Stick-it Flexible is an inorganic sticker coated with liquid ceramic paint.

This paint is environmentally friendly inorganic liquid, which dissipates the heat generated by electronic equipment using the excellent radiation characteristics of ceramics.

By painting a 50 to 150um thin coating on electronic devices and parts at room temperature, it realises a high radiation ratio of between 0.9 and 0.95 at around 80C, which reduces the heat of an operating electrical device by 5 to 20%.

The heat radiation sticker offers the same characteristics as those of the liquid ceramic paint.

It contains none of the chemicals required to register to a local government under the Pollutant Release and Transfer Register (PRTR) regulation.

The sticker is only 0.3mm thick, and so can be easily cut with scissors and stuck to even curved surfaces.

It can be stuck on aluminium, stainless steel, or even copper, nickel-plated steel sheet and epoxy resin - surfaces which are not easily coated with liquid ceramic paint.

It has a heat resistance of 120C, which is compliant with UL510 flame retardancy (FR), the flameproof standard for insulating tape.

The Stick-it Flexible and the ceramic paint can be used for wide range of devices, including power supplies, lighting equipment, and automobiles, replacing existing metal-plate heatsinks.

As a result, they minimise the size, extend the life cycle, and reduce the noise and power consumption in electronic equipment.
