5g, Japanese material science and technology research company, key words of high heat resistant transparent resin
Japan materials technology research Co., Ltd. is a company that re uses the chemical technology that is not used, and carries on the enterprise. At present, the Japanese materials research company plans to expand the related businesses of high-performance materials such as high heat-resistant transparent resin, and has signed authorization contracts with AGC, Mitsui chemical, JNC, JSR and other companies.
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, the Japanese material science and technology research company will expand new horizons in high heat-resistant materials. This material is a transparent resin material with tricyclic decane structure. JSR and Tokyo University of technology have jointly studied and found that at present, Japanese material research company has obtained the technical authorization of bis (vinyl sulfone) tricycleo [5.2.1.02,6] (vstcd) and its polymer.
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.
Japan materials technology research Co., Ltd. plans to apply this material to transparent refracting materials such as urethane, acrylic acid and polycarbonate, and further achieve the goal of industrialization.
In addition to the above-mentioned high temperature resistant transparent resin, Nippon materials technology research Co., Ltd. has another exclusive authorization from Tokyo University of technology, 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.
In addition to the company, many other companies have also focused on new heat-resistant materials.
For example, on December 19 last year, Toray Industries Co., Ltd. of Japan released a polyphenylene sulfide (PPS) film, which maintained excellent dielectric properties and chemical stability of PPS polymer.
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 to Toray, Japan's NOK company will promote the industrialization of the newly developed exclusive heat transfer material "tran-q clay".
Tran-q clay "has a thermal conductivity of 2.8W / (m.k), heat resistance of 200 ℃ and excellent insulation. In addition, it can adjust the thermal 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.
NOK also plans to achieve mass production in 2020 after obtaining industrial specifications, fire resistance and long-term reliability assessment.
