Many users often cannot distinguish the difference between thermal conductive silicone and thermal conductive silicone grease, and do not know how to choose when purchasing, making it easy to confuse silicone and silicone grease. Although silicone and silicone grease are only literal differences and both are thermal conductive materials, their characteristics still have significant differences. The following series will promote the difference between thermal conductive silicone and thermal conductive silicone grease.
Thermal conductive silicone is a single component dealcoholized room temperature cured silicone rubber that has the effect of cooling and bonding electronic devices. This product can be cured into a high hardness elastomer in a short period of time. After curing, it closely adheres to the contact surface to reduce thermal resistance, which is beneficial for the heat source to conduct heat to the surrounding heat sink, motherboard, metal shell, and outer shell. In addition to thermal conductivity, this product also has a certain bonding strength, making it suitable for applications that require fixation and no displacement. This type of product can generally dry quickly or solidify quickly under heating conditions, in order to accelerate customer production processes and reduce the characteristics of fixed production industries.
Thermal conductive silicone grease is in the form of oil, without adhesive properties, will not dry and solidify, and is produced using a special formula. It is composed of metal oxides with good thermal conductivity and insulation properties and organosilicon oxides. This type of product has excellent thermal conductivity, good electrical insulation, a wide range of operating temperatures, and good stability during use.
