Black (cryptocrystalline) graphite GLS-1 (GOST 5420-74), obtained by grinding graphite ores, is intended for use in foundry and metallurgical production.
In the foundry industry, GLS graphite is used as a filler for non-stick paints for coating molds and cores for cast iron and non-ferrous castings, sand molding and slag-forming mixtures and heat insulators.
Graphite is packaged in four- or five-layer paper bags of any brand or in soft specialized containers for bulk cargo of the MK type, manufactured according to regulatory and technical documentation.
