BPG 8508


BPG 8508 is a sheet made of expanded graphite reinforced by a stainless steel tanged insert (316L – thickness 0.1 mm) which improves its resilience and resistance to blow-out.



Due to its high compressibility and high resilience makes BPG 8508 suitable for high demanding conditions in all industries. Suitable for steam, gases, hydrocarbons and aggressive (non-oxidizing) media.
