What Is an Insulation Support Block?
An insulation support block is a critical marine component designed to provide structural support and electrical insulation within shipbuilding applications. These blocks are engineered to withstand heavy loads while preventing galvanic corrosion and ensuring the integrity of electrical systems in harsh maritime environments.
Core Functionality
Insulation support blocks serve as non-conductive load-bearing elements, typically installed in rudder stocks, stern tubes, and hatch covers. They isolate metal components to prevent current leakage and corrosion, extending the lifespan of your vessel's mechanical systems.
Material Composition
Constructed from high-performance polymer composites, such as our patented SL-IIIA series, these blocks offer superior pressure resistance, self-lubricating properties, and exceptional durability against acid, alkali, and seawater corrosion compared to traditional materials.
