The expanded graphite powder products have various forms, and the common ones are powder or formed blocks after processing. According to your actual application scenario and process requirements, we further process it. Such as make it into a specific shape of the heat transfer module or filling material. To meet different size and functional requirements.
Expanded graphite powder has many excellent properties.
High chemical stability
It is resistant to corrosive substances such as strong acid and alkali.
Good high temperature resistance
It can maintain stable struktur in high temperature environment. Its porous structure gives it a strong adsorption capacity, can adsorb a variety of substances.
Good flexibility and compressive resilience
You can deform and restore it to the original state under certain pressure. At the same time, its electrical conductivity is also relatively excellent. And it has certain application potential in the field of electricity conduction.
If you want to deeply understand the thermal conductivity, adsorption characteristics and other technical parameters and application details of expanded graphite powder, we will provide you with detailed technical guidance and rich application case reference.
