Rubber Compound: Marine-grade rubber compounds are formulated to resist saltwater corrosion, UV degradation, and microbial growth. Nitrile rubber (NBR), neoprene, and polyurethane are common choices.
Metal Shell: Marine-grade metals, such as stainless steel or bronze, are used for the outer shell to provide corrosion resistance and durability.
Saltwater Compatibility: The bushing must be resistant to saltwater corrosion, which can degrade the rubber and metal components over time.
Antimicrobial Treatment: Antimicrobial additives can help prevent the growth of marine organisms, such as algae and barnacles, which can reduce the bushing's effectiveness.
