When exposed to heat, expandable graphite expands and forms an intumescent layer on the material surface. This slows down the spread of fire and counteracts the most dangerous consequences of fire for humans, the formation of toxic gases and smoke.

作为一种新型功能性碳素材料，膨胀石墨(Expanded Graphite，简称EG)是由天然石墨鳞片经插层、水洗、干燥、高温膨化得到的一种疏松多孔的蠕虫状物质。

Expanded graphite (EG) is a kind of carbonaceous raw materials obtained from natural flake graphite, which is treated by chemical or electrochemical intercalation and then been heated instantaneously to produce high-temperature expansion. …

2024年9月28日 · In this guide, we will take a look at some critical facts about expandable graphite. What is Expandable Graphite? This is a form of Carbon material under the graphite family. It is made by incorporating molecules of acids into the structure of graphite. Originally, the structure of graphite is in layers with spaces in between them.

In recent years, a large variety of expandable graphites has been developed which are suitable for the production of graphite foils, sheets, strips, gaskets, sleeves, bearings, moulded parts, etc. Expandable graphite has penetrated a wide and promising range of applications. One focus today is on flame retardancy.

2023年4月1日 · Expanded graphite has been widely used in lithium-based batteries owing to its distinct chemical/physical characteristics and has gradually narrowed the gap. This article reviews general expanded graphite synthesis methods and composite strategies for high-performance lithium-based batteries.

2024年6月14日 · Expanded graphite has promising potential environmental applications due to its porous structure and oleophilic nature, which allow it to absorb large quantities of oil. The material is produced...

The properties of expandable graphite, i.e. initial expansion temperature and degree of expansion, are primarily defined by the quality of intercalation (proportion of intercalated layers) and by the intercalation

2023年6月25日 · Expanded graphite (also known as exfoliated graphite, EG) is a kind of modified graphite having a certain degree of separation of most of the carbon layers. In other words, EG is a type of carbon material with a loose, porous, and worm-like structure.

2024年5月25日 · Expanded graphite is a versatile engineering material that offers exceptional thermal management properties. Its ability to expand and create porous, flexible forms with high thermal and electrical conductivity makes it ideal for a range of advanced applications, particularly in thermally demanding environments.
