Silicone-Base Thermal Pad: IMTH70 Series – High Performance Type

KITAGAWA INDUSTRIES America’s IMTH series, silicone-based thermal pads are popular items for many applications such as cell phones, display, laptop, routers, network servers, smart meter, car navigation, printer, digital camera etc.

IMTH70 series thermal pads have a high conductivity of 7.0 W/m*K and is available in 0.5 mm to 10 mm thicknesses. They are also the superior and longer lasting solutions in comparison to thermal grease. Thermal grease or paste can be very difficult to handle. Its liquid form makes it messy to apply, and unless once completely covers an entire surface evenly, areas with less thermal grease will have less performance.
