General situation and development status of thermal conductive material industry
1、Overview of thermal conductive materials industry
With the gradual increase and complexity of the integrated functions of single electronic equipment and the gradual reduction of the volume of the equipment itself in the 5g era, higher requirements are put forward for the thermal management technology of electronic equipment, such as the requirements for the thermal conductivity of thermal conductive materials and the thermal stability of long-term work. This trend provides an opportunity for the development of thermal conductive materials.
At present, thermal conductive materials are mainly divided into thermal conductive paste, flake thermal gap filling material, liquid thermal gap filling material, phase change thermal conductive interface material, thermal conductive gel and graphite film.

2、 Analysis on the development status of thermal conductive materials industry in China
At present, consumer electronics is becoming smaller, lighter and more intelligent. The investment of communication base station equipment brought by 5g business and the vigorous development of power battery are expected to greatly boost the demand for thermal conductive materials. According to statistics, the global market scale of interfacial thermal conductive materials is 800 million US dollars in 2015, and it is expected to reach 1.1 billion US dollars in 2020, with CAGR of 7%.
Statistics of global market size of interfacial thermal conductive materials from 2015 to 2020
According to statistics, by the end of 2018, the number of 4G base stations of China Mobile has reached 2.41 million, and the network coverage rate of administrative villages has exceeded 97.8%, which effectively meets the demand of rapid growth of 4G traffic. By the first half of 2019, the number of 4G base stations of China Mobile has reached 2.71 million, and 30 new base stations will be added in 2019.
