At present, 5g can be said to be the focus of various industries. 5g brings convenience and hope to people, but also brings a series of problems, such as more power consumption and more heat.
5g heating problem is very serious, at the same time, 5g construction is also in urgent progress, in this case, heat dissipation materials and heat-resistant materials will also usher in a new wave of market.
Recently, many companies are going to expand new horizons in high heat resistant materials. This material is a transparent resin material with tricyclic decane structure, which was found by JSR and Tokyo University of technology.
Using this monomer as the raw material of polymer, it is expected to develop a new transparent resin with high refractive index, high Abbe number and other optical properties, as well as low moisture absorption, high thermal stability, high glass transition temperature (TG) and other characteristics. It is planned to apply this material to transparent refracting materials such as urethane, acrylic acid and PC, and further achieve the goal of commercialization.
In addition to the high temperature resistant transparent resin, there is also an oxide ceramic material. This kind of ceramic material has a negative thermal expansion rate of 187ppm for every 1 ℃ rise in temperature under room temperature. If this ceramic material with a highly negative linear coefficient of thermal expansion is used as a filler, only a small amount of addition is needed, and it is expected to achieve the function of adjusting thermal expansion. It is currently planned to use this material in 5g related electronic parts.
This kind of film is suitable for the PPS film of 5g circuit substrate. Compared with the general PPS film, its heat resistance is increased by 40 ℃.
In addition, it will promote the industrialization of tran-q clay, a newly developed exclusive heat transfer material. The thermal conductivity of tran-q clay "is 2.8W / (M? K) It has heat resistance of 200 ℃ and excellent insulation. In addition, it can adjust the heat conductivity or hardness through the material design. Because it does not need hardening time and is not greasy, it is expected to help improve the productivity during assembly.
