Specialty Carbon Graphite Products for Marine Environments 

SPECIALTY CARBON GRAPHITE PRODUCTS FOR MARINE ENVIRONMENTS

Certain applications require our product to operate underwater, both freshwater and saltwater. We have specific grades that are able to be used in these conditions as they are resistant to decomposition and failure even when used in the harsher saltwater environment. This is especially crucial for underwater operations where maintenance is time-consuming and costly (e.g., pumps or turbines operating at the ocean floor).
