The thermal conductivity of different substrates and fillers is different, and the interaction between the two is different.
The higher the thermal conductivity of the substrate and the filler, the better the degree of mutual bonding, and the better the performance of the thermally conductive plastic
.
Thermally conductive plastics are highly thermally conductive plastics made by uniformly filling polymer matrix materials with thermally conductive fillers
.
Thermally conductive plastic has light weight, uniform heat dissipation, convenient processing and high design freedom.
It can be used to produce LED lamp bases, radiators, heat exchangers, pipes, heating equipment, refrigeration equipment, battery shells, electronic packaging products, etc.
, and are widely used in Electronics, electrical, automotive, medical, new energy, aviation and other fields
.
According to the "In-depth Research and Development Prospect Forecast Report of China's Thermally Conductive Plastics Industry in 2020-2025" released by the New Sijie Industry Research Center, the global thermally conductive plastics market has an average annual compound growth rate of 14.
1% from 2015 to 2019.
The market size in 2019 is approximately US$6.

.
North America has a developed economy.
In addition to electronics, electrical, automotive, medical and other industries, emerging industries such as new energy continue to develop and become the world's largest demand market for thermally conductive plastics
.
Driven by the rapid economic development and continuous expansion of industrial scale in China, India and other countries, the Asia-Pacific region has become the fastest growing region in the global demand for thermally conductive plastics, and the proportion of demand is constantly increasing
.
The factors that affect the performance of thermally conductive plastics mainly include the properties of the polymer matrix material, the properties of the filler, the bonding characteristics and the interaction between the matrix and the filler
.
The matrix materials mainly include nylon 6/nylon 66, LCP, polycarbonate, polypropylene, PPA, PBT, polyphenylene sulfide, polyether ether ketone, etc.
; fillers mainly include alumina, aluminum nitride, silicon carbide, graphite, high thermally conductive carbon powder
.
The thermal conductivity of different substrates and fillers is different, and the interaction between the two is different.
The higher the thermal conductivity of the substrate and the filler, the better the degree of mutual bonding, and the better the performance of the thermally conductive plastic
.
According to the electrical conductivity, thermally conductive plastics can be divided into two categories: thermally conductive plastics and thermally conductive insulating plastics.
.
Thermally conductive plastics are made of metal powder, graphite, carbon powder and other conductive particles as fillers, and the products are conductive; thermally conductive insulating plastics are made of metal oxides such as alumina, metal nitrides such as aluminum nitride, and non-conductive silicon carbide.
The particles are made of fillers, and the product has insulating properties
.
In comparison, thermally conductive insulating plastics have relatively low thermal conductivity, and thermally conductive and electrically conductive plastics have better thermal conductivity
.
Globally, thermally conductive plastics manufacturers mainly include BASF, Bayer, Hella, Saint-Gobain, DSM, Toray, Kazuki Chemical, Mitsubishi, RTP, Celanese, and the United States.
PolyOne and others
.
Compared with the international giants, China's thermally conductive plastic companies are weaker in terms of scale and capital, and lack R&D and innovation capabilities.
Except for a few companies, most companies focus on the low-end market competition, and the overall core competitiveness needs to be enhanced
.
Industry analysts in Xinsijie said that with the continuous upgrading of technology, electronic components and mechanical parts are getting smaller and smaller, more and more integrated functions, heat dissipation problems are becoming more prominent, and the comprehensive performance of thermally conductive plastics is excellent, and the application fields are constantly expanding.
.
China's economy continues to grow steadily, the scale of the manufacturing industry continues to expand, and technology continues to upgrade.
The market demand for high-performance thermal conductive plastics continues to rise
.
In this context, China's thermally conductive plastics industry needs to continuously improve its core competitiveness in order to achieve import substitution of high-end products
