Description

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.

This material data has been provided by SGL Carbon.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
