Thermal paste is a paste compound of thermal interface material that does not dry out; it can transfer heat from the heating device to the heat sink and the chassis. The product can still be insulated if the thermal metal oxide is filled. Thermal conductivity has low permeability, good temperature resistance and low fluidity. It is also very stable at high temperatures. Even if the temperature reaches200 °C, it will not crack due to drying. It can be manually operated and screen printed.
