Hi-G Thermal Grease
by YAHAM | Jun 29, 2018 | Company news | 461


Hi-G thermal grease is a thermal conductive silicone grease complex. This product introduces the nano-graphene of excellent thermal conductivity as the main thermal filler, greatly reducing the thermal resistance of the material to enhance the overall thermal conductivity of the product. Products are featured by low oil bleeding, being resistant to high and low temperature, anti-aging, insulative etc. which is designed for power amplifiers, transistors, tubes, CPU and other electronic devices heat conduction and heat dissipation, so as to ensure that electronic equipment, instruments and other electrical performance stability.


Graphene is an allotrope of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It is a non-metallic crystalline material, which achieves the heat conduction by the mutual restraint and mutual harmonic vibration of crystal structure units. Its thermal conductivity can reach 5300W/mK, so graphene materials can be used as excellent super-high thermal conductivity materials.


Hi-G thermal grease fills the graphene into the silicone compound, and the graphene particles and the organic silicon particles contact each other to form an unobstructed mesh-like or chain-like heat conduction network, which greatly reduces the thermal resistance. It can rapidly spread lateral heat in the center of the interface between electronic components and heat sinks, and then conduct heat from the longitudinal direction to the radiator, thereby achieving high efficiency and even thermal dissipation.


In addition to the high thermal conductivity values, the two-dimensional geometry of graphene, strong coupling with the matrix material, and low cost make graphene an ideal filler for the interface material.



Graphene Application Technology Center


Yaham established Graphene Application Technology Center on December,2015.At the beginning of establishment, Yaham and Department of Physics of Xiamen University build up research cooperation. Combining Yaham’s products features, through using Graphene’s thermal conductivity, Yaham Graphene Application Technology Center aim at develop and produce graphene thermal conductive polymer composites. On the one hand it meets the company’s products’ thermal requirements; on the other hand, it can also provide most favorable thermal management solution for the high heating products in the market.
Graphene Application Technology Center has set up three laboratories: graphene power laboratory, graphene film laboratory and graphene application laboratory. At present the technology center accumulated R&D investment of about 300 million, introduced a variety of graphene power and film preparation equipment, polymer composite materials processing equipment and the corresponding detection equipment.
