Expandable graphite
Also called oxidized graphite
It is a unique raw material that is flame retardant when used with fire retardant paints. Also used as an ingredient in coatings and sealants. It has strong flame retardant properties that prevent the melting of rubber and polymeric materials as a result of exposure to high temperatures. It is used as a thermal insulation of metal surfaces in industries.
Consider the brand GRAFT EG 350 - this is one of the varieties of graphite, which has a degree of expansion of 350 ml / g. The product was obtained as a result of oxidation with sulfuric acid.

What does it look like?
In fact, it is a crystalline powder that has an oily sheen. The powder itself has a dark coal tint, while with a metallic sheen, without a pronounced smell.

Where is it used?
Expanding graphite is widely used for the manufacture of fire-retardant coatings at enterprises;
intumescent compositions for polymers and rubber products;
used for electrodes, as well as for the manufacture of heating elements;
in the field of building electrical machines, it is used for bearings.

Assigned CAS No. 7782-42-5
The temperature at which the expansion of the product begins - 170 C
The expansion rate ranges from 350 to 380 percent.

Storage and transportation of graphite
thermal expanding 250 - 350:

Guaranteed shelf life of oxidized graphite is 12 months from the date of manufacture of the product.
Oxidized intumescent graphite should be stored in a cool, dry, well ventilated area on pallets. Be sure to keep away from reducing agents, potential oxidizing agents;
also away from any food raw materials. In this case, the transportation of graphite is carried out by any transport.
