In 2026, the global consumer electronics industry continues to iterate and upgrade, with major electronic brands launching ultra-thin lightweight smart phones, multi-fold flexible screen devices, high-power wearable smart devices and ultra-thin commercial tablets one after another. While improving product performance and portability, the ultra-compact internal structural design of electronic equipment leads to reduced internal heat dissipation space and aggravated heat accumulation. High-power chip operation and high-frequency functional use make the equipment face prominent overheating problems, which easily cause equipment jamming, power consumption acceleration and performance attenuation, seriously affecting user experience and equipment service life.
Traditional electronic heat dissipation materials such as metal heat conduction sheets and rigid ceramic heat dissipation materials have obvious application limitations in new flexible and ultra-thin electronic devices. Metal materials have high density, poor flexibility and thick thickness, which cannot meet the ultra-thin and lightweight design requirements of consumer electronics. Rigid heat dissipation materials are easy to crack and damage during device folding and bending, and cannot adapt to the flexible working state of folding screen equipment. Ordinary flexible graphite heat-conducting films on the market have problems such as low thermal conductivity, poor bending resistance and easy delamination after long-term use, which cannot meet the long-term stable heat dissipation needs of high-end consumer electronics.
The new generation of high-performance flexible graphite heat-conducting films have achieved comprehensive breakthroughs in thickness, flexibility, thermal conductivity and structural stability after technological iteration. Through ultra-thin layered pressing, molecular structural optimization and flexible modification treatment, the flexible graphite film has ultra-thin thickness (minimum 0.01mm), ultra-high in-plane thermal conductivity, excellent bending resistance and compression resistance. It can be freely bent, folded and fitted with irregular equipment structures, perfectly adapting to the heat dissipation design needs of ultra-thin and flexible consumer electronic devices, and has become the preferred heat dissipation material for the global high-end consumer electronics industry.
The technical upgrading of flexible graphite heat-conducting films has driven the rapid expansion of the global market scale. With the large-scale popularization of folding screen mobile phones, ultra-thin tablets and high-end wearable devices, the market demand for high-performance flexible graphite heat-conducting films has maintained a high growth rate. Industry data shows that the global consumer electronics-grade flexible graphite film market size will grow at a compound annual rate of 13.5% from 2026 to 2030, with huge market development potential. However, the high-precision production and flexible modification technology of ultra-thin graphite films have high technical barriers, and high-quality products are in short supply in the market.
Jincheng Graphite has long focused on the R&D and production of functional flexible graphite materials for consumer electronics, and has independently developed a new generation of ultra-thin high-flexibility graphite heat-conducting film products through continuous technological innovation. The enterprise optimizes the ultra-thin layered pressing process and molecular rearrangement technology, breaking through the technical bottleneck of ultra-thin graphite film delamination and low thermal conductivity. The developed flexible graphite film has a minimum thickness of 0.01mm, thermal conductivity up to 450W/(m·K), and can withstand more than 100,000 times of repeated bending without cracking or delamination, with excellent long-term stability.
In terms of product customization, Jincheng Graphite can provide personalized size cutting, surface insulation treatment, adhesive coating and composite lamination services according to the structural design and heat dissipation requirements of different electronic devices. The enterprise's flexible graphite film product matrix covers ultra-thin heat-conducting films for mobile phones, bending-resistant heat dissipation films for folding screens, lightweight heat-conducting gaskets for wearable devices and other full-range products, which can fully meet the differentiated heat dissipation needs of various high-end consumer electronic equipment.
Compared with similar international products, Jincheng Graphite's flexible graphite heat-conducting films have more balanced performance, higher flexibility and more stable heat dissipation effect, with obvious cost performance advantages. At present, the enterprise's products have entered the supply chain of many global top consumer electronics brands, and are widely used in high-end smart phones, folding screen devices, smart watches and ultra-thin tablet products, helping terminal equipment achieve efficient heat dissipation, low power consumption and long-term stable operation.
Looking ahead, with the continuous innovation of flexible electronic technology and the upgrading of consumer electronic products, the application scope of flexible graphite heat-conducting materials will be further expanded. Jincheng Graphite will continue to iterate flexible graphite material technology, develop ultra-thin, high-strength and multi-functional composite graphite heat-conducting materials, further enrich consumer electronics-grade graphite product lines, and provide high-quality core heat dissipation material support for the upgrading of global consumer electronic equipment.
