Expanded graphite is made of expandable graphite powder, which has a large volume after expansion, so when we choose expanded graphite, the purchasing specifications are generally 50 mesh, 80 mesh and 100 mesh. Here’s the editor of Furuite Graphite to introduce the resilience and compressibility of expanded graphite:
Expanded graphite, also known as flexible graphite, is made from flake graphite by special processing. The expanded graphite material is loose and has the characteristics of porosity, curling, strong adsorption and large surface area. It is the basic element for making various sealing materials, and can be mixed with other materials to make flexible graphite materials such as expanded graphite plates, sealing gaskets, expanded graphite packing rings and expanded graphite packing.
Expanded graphite has strong high temperature resistance and is mainly used in fire doors, fire windows and other occasions. The expanded graphite material, rubber material, accelerator, vulcanizing agent, reinforcing agent, inorganic flame retardant, filler, etc. are mixed, vulcanized, and molded to produce expanded sealing strips of various specifications. This expanded sealing strip can block the smoke flow from beginning to end in normal temperature and fire.
The expanded graphite produced by Furuite Graphite can instantly expand by 150~300 times when exposed to high temperature, which increases its softness, resilience and plasticity. If you need it, you can leave a message for us on the website or call for consultation.
