Maintenance Of Polyurethane Fenders

Polyurethane fenders play a vital role in the dock and ship fields. Maintenance of polyurethane fenders is crucial to ensure their long-term effectiveness and safety. Here are some tips on how to maintain polyurethane fenders:

1. Regular Cleaning: Clean the fender surfaces regularly with water and mild detergent to remove dirt, salt, and other contaminants. Avoid using strong acidic or alkaline cleaners to prevent damage to the fender material.
2. Check for Damage: Regularly inspect the fender surfaces for cracks, wear, or other physical damage. If damage is found, promptly repair or replace the affected parts to prevent further deterioration and maintain the fender’s performance.
3. UV Protection: Avoid prolonged exposure to strong sunlight as UV rays can degrade the durability of polyurethane. Use UV protective coatings or covers periodically to extend the lifespan of the fenders.
4. Maintain Elasticity: The elasticity of polyurethane fenders is crucial for effective impact absorption. Ensure the fender surfaces stay dry and avoid pooling of water or moisture to prevent the material from becoming stiff or losing its elasticity.
5. Avoid Chemical Corrosion: Prevent contact with chemicals such as petroleum products, solvents, or strong acids/bases which can damage or corrode the fender material, reducing its performance and lifespan.
6. Inspect Fixings: Regularly check the fixing systems (e.g., chains, ropes) to ensure they are in good condition without rust or wear, ensuring the fenders can effectively stay in place as needed.

By implementing regular maintenance and proper usage management, polyurethane fenders can maintain their performance and safety over the long term, providing reliable protection for vessels and docks.
