Silicone‐Free Thermal Pad: CPVS Series
Soft (ASKER C 18) silicone-free thermal pad
Many optical, medical, and sensor applications cannot allow silicone particles to be located within their enclosures. To meet the needs of these industries, KITAGAWA INDUSTRIES America offers a line of non-silicone based thermal pads/Thermal Interface Materials (TIM) to eliminate any worries regarding siloxane gasses. These are available in thermal conductivity between 2.0 W/m*K. Like silicone based thermal pads, self-tackiness on both sides and one side self-tackiness are available as options. Available thicknesses range from 0.5 – 2.0 mm.
Structure
CPVS-F Series:
One side PET, one side naturally tacky
CPVS Series:
Both sides naturally tacky
Features
Soft type thermal pads provide low thermal resistance, while conforming well to uneven surfaces.
Soft type thermal pads more evenly distribute pressure.
