五、Product description 

Thermally conductive silicone sheets fill the air gap between the heating element  the heatsink  metal base,  their flexible, elastic properties allow them to be used to cover very uneven surfaces. Heat is transferred  the separator  the entire PCB to the metal housing  diffusion plate, thus improving the efficiency  service life of the heating electronic component.


Shelf Life: 12 months  

Storage conditions: room temperature, cool  dry place   

Relative humidity:RH<70%
