The low-volatile thermal pad is a kind of heat-conducting medium which is made of a specially treated silicone gel as a base material and added with various polymer materials with excellent thermal conductivity and synthesized by a special process. It can fill the gap and complete the heat transfer between the heat-generating part and the heat-dissipating part.
At the same time, it also plays the role of insulation, shock absorption, sealing, etc., which can meet the design requirements of miniaturization and ultra-thinness of equipment.
LSK series thermal silicone pad is environmentally friendly, soft and easy to compress; high efficiency, high insulation, high flame retardant, high compression; high and low temperature resistance, no oxidation, low oil and weather resistance. It is suitable for various demanding applications as it has good thermal conductivity and is suitable for filling the gap of the mechanism, improving the heat transfer efficiency between the heating element and the metal heat sink.
