Polyurethane fenders have good corrosion resistance, wear resistance, and durability. The products are made of environmentally friendly materials and new polymer materials with adjustable high elastic modulus. The appearance is a new type of spray polyurethane developed in recent years. (Polyurea) elastomer technology to form a high-quality uniform outer layer with extremely high wear resistance and non-marking properties, which can effectively increase the elasticity of the product and corrosion resistance such as seawater. This ensures that the fender does not break and reduces damage.
