SUNGRAF COMPANY has got the certifcate of REACH from EU ,whose expandable graphite can export to EU market legally.

Expandable graphite is the natural flake graphite with chemically treatment , after high temperature expansion ,becomes”graphite worms”, the expansion volume is from 100 to 600 times. It is light, with good electrical conductivity and thermal resistance, thermostability, acid and alkali corrosion resistance, good elastic resilience, lubricity, plasticity, non-toxicity and chemical stability, known as the “king of seals”.
1. In the sealing industry , as a flame retardant seal material can be made into flexible graphite roll or sheet, graphite composite sheet, gasket and so on.
2. In flame retardant area, for fire proof sealing strip, construction fireproof plugging, fire board, fireproof paper, used in flame retardant plastic, flame retardant antistatic coatings.
3. Used as a high energy battery materials and environmental protection fields of adsorption materials.
4. It is one of the main raw materials of oxygen-proof insulation heating agent in the iron and steel industry, it also can be used as thermal and sound insulating materials, fireproof safe materials, shielding materials.


Weclome the companies who use expandable graphite in European market to inquiry.
