BPG 8502


BPG 8502 is a sheet made of expanded high oxidation-resistant graphite foil with a purity of more than 98%.



Due to its high compressibility and good resistance to creep makes BPG 8502 suitable for demanding conditions in the petro-chemical, - process, - chemical, - power plant industries, especially for pumps, valves and compressors.
