FG 320

FG 320 is manufactured from exfoliated graphite through acid treatment with 100% acids washed out by DM water. The manufacturing process is mechanical without incorporation of any additives or bonding material, resulting in flexible pure graphite sheet with carbon content 99% to 99.9%. Highly resilient and easily adapts to irregularities of flange or surface to make perfect seal. Suitable for metallic, glass, and enamel flanges, designed for trouble-free change over which ultimately reduces maintenance cost. Dimensionally stable under extreme pressure surge and suitable for cryogenic services.

Ultra-high purity with 99% to 99.9% carbon content

Extreme temperature capability from -200°C to 550°C

Highly resilient and adapts easily to surface irregularities

SSF 321

SSF 321 sheet is manufactured from plain SS sheet sandwich between two layers of flexible pure graphite sheet. The manufacturing process is mechanical without incorporation of any additives on bonding materials. SS sheet insert graphite gaskets are suitable for metallic, glass, enamel flanges and are designed for trouble-free change over which ultimately reduces maintenance cost. Dimensionally stable under extreme pressure surge and suitable for cryogenic services.

SS foil reinforcement increases mechanical strength

Chemical properties of flexible pure graphite remain intact

Resistant to almost all non-chemicals
