Thermal Grease
Basic performance of thermal grease/thermal grease "Jiadi New Material:
1Insulation, high thermal conductivity
2 Low sedimentation, low oil permeability, good thixotropy
3Superior high and low temperature resistance, excellent weather resistance, radiation resistance and superior dielectric properties
5 Superior chemical and mechanical stability
6Store at room temperature
The liquid part of thermal grease is composed of silica gel and silicone oil. Most of the products on the market use simethicone as raw material, and the boiling point of simethicone is between 140°C and 180°C, which is prone to volatilization. , There will be oil leakage, there will be traces of grease on the circuit board. The grease detachment phenomenon will make the customer feel that the silicone grease is dry. The raw materials of Jiadi New Materials do not contain solvents or low molecular weight silicone oils. Therefore, the products of Jiadi New Material will not evaporate after drying and heating.
Thermally conductive silicone grease is prone to instability in long-term use: thermally conductive silicone grease is sandwiched between the chip and the heat sink to maintain a liquid state and will not solidify to fill the gaps between the interfaces cheaply. Thermally conductive silicone grease is difficult to apply without any bubbles. Many electronic components will have a temperature cycle (temperature from low to high and then from high to low, such as PC). Thermal expansion and contraction will cause bubbles in the silicone grease The volume changes and the silicone grease is extruded out of the gap after thermal cycling.
The solution of Jiadi's new material is to control the low-molecular-weight siloxane in the silicone grease to keep the silicone grease non-volatile and non-oily at high temperatures. At the same time, strictly control the viscosity range so that the silicone grease maintains good operability. Will there be silicone grease extrusion. After 20,000 power cycle experiments, the thermal conductivity of the LS series remained basically stable. Users can use Jiadi's new material products with confidence.
The thermal conductive silicone grease of Jiadi New Material has good thixotropy and low sedimentation characteristics. Easy to store and apply
