Graphene thermal conductive film meets the higher heat flux requirements of 5G products

On August 11, China Pingmei Shenma Group Kaifeng Pingmei New Carbon Material Technology Co.
, Ltd.
said that the company has developed the world's highest thermal conductivity graphene thermal conductive film, which has entered the pilot stage, and the performance can fully match the demand for higher heat flux of
5G products.
At the same time, the company has also developed high-performance fuel cell bipolar plates
.

Since last year, the company has cooperated with Tsinghua University to introduce advanced technology and equipment to produce vapor deposition graphene with the highest scientific and technological level of carbon materials, and then develop graphene thermal conductive film
.
Its thermal conductivity is 3~4 times higher than that of the same type of products on the market, and the thickness can be arbitrarily controlled, and the single film can reach hundreds of microns, which can quickly transfer the heat generated by 5G electronic product chips to achieve heat
soaking.

According to reports, the company's graphene thermal conductive film has been successfully piloted and will be put into industrial production
in 2021.
It is estimated that the first phase of the project can achieve a production capacity of 100,000 square meters, with an annual output value of 40 million yuan; The second phase plans to build a production capacity of 500,000 square meters, with an annual output value of 200 million yuan, to help the rapid advancement of
5G applications.
