SGL Carbon is the global market leader for graphite based process equipment, systems and parts. DIABON is our tradename for impervious graphite materials used for engineered solutions in corrosive applications. Based on application know-how of the largest equipment reference base on market and more than 70 years of design and manufacturing expertise, DIABON materials are continuously improved and globally considered as quality benchmark for corrosive applications. DIABON phenolic resin impregnated graphite
is certified by FDA. DIABON is a composite material made of:
a porous graphite base material
impregnated with a phenolic resin or a fluoropolymer to make it impervious.
Customer benefits:
Long lifetime and safety
High plant availability
Compactness
Material upgrade options:
CARBOGUARD®: A carbon fiber reinforcement of graphite and
silicon carbide parts e.g. tubes, tubesheets, headers,
columns etc.. An increase of operational reliability and safety
are the benefits. It extends the range of application under
high-stress conditions like temperature or pressure shocks.
Resin-layer-free design: Tubes can be manufactured without
a resin layer on the inside. This design is beneficial for very
clean requirements or for falling film applications.
