Thermal Pad Vs Paste

Thermal Pad Vs Paste

Many customers often can’t tell the difference between thermal pad and thermal paste, and do not know how to choose when purchasing? Friends who have not contacted this line believe that they may think that thermal pad and thermal paste are the same product, but they are not. Although there is only one word difference, the difference is a thousand miles away. Although thermal pad and thermal paste are both thermal gap filler, but the performance is still different, let’s distinguish the difference between thermal pad and thermal paste.

Thermal paste and thermal pad have similar properties and similar production processes, except that a viscous substance is added to the formula to make it have better bonding properties.

Thermal gel is a one-component dealcoholized room temperature curing silicone rubber. The condensation reaction of moisture in the air releases low molecules to cause cross-linking and curing. It can be cured into an elastomer with high hardness in a short time. It has the functions of cooling and bonding electronic devices. After curing, it is closely attached to its contact surface to reduce thermal resistance, which is beneficial to the heat conduction between the heat source and its surrounding heat sinks, motherboards, metal shells and outer casings. Thermal silicone series products have the advantages of high thermal conductivity, good insulation performance and easy to use. Thermal silicone products have good adhesion to metals including copper, aluminum, stainless steel, etc. Does not produce corrosion.

And what we usually call thermal grease is a kind of grease paste, which has no adhesive properties and will not dry. It is produced with a special formula, using metal oxides and organosiloxane with good thermal conductivity and insulation. compound. Thermal grease has excellent thermal conductivity, good electrical insulation, wide operating temperature (working temperature -50 ℃ ~ 200 ℃), stable heat dissipation, low consistency and good construction performance, thermal grease is non-toxic , Non-corrosive, odorless, non-drying, insoluble.

Through the introduction of the above content, I believe that everyone has a certain understanding of the difference between thermal pad and thermal paste. Although silicone grease and silicone are only literally one word apart, and they are both thermal conductive materials, they are completely different. Two things. Relatively speaking, silicone grease has a wider scope of application and is almost suitable for the heat dissipation conditions of any electronic product; and thermal pad is difficult to remove once attached, so it is mostly used in some occasions that only require one-time bonding .
