Development of Buoy Materials and Advantages of Foam Buoys (Material Evolution and Basic Characteristics)
With the development of buoys / fenders, the manufacturing materials have evolved from PVC and polyurethane to EVA foam. The foam buoys are made of high-quality EVA foam, which performs excellently in weather resistance and has a long service life. This product is soft and has high resistance to impact, rupture and low temperatures.
01
Reinforced Coating and Buoy Shapes (Structural Reinforcement and Diverse Shapes)
It features a reinforced polyurea-coated skin, with high energy absorption and low reaction force. Its overall performance is better than that of pneumatic fenders and it has been widely used in ports, offshore and ship berthing. The shapes of the buoys can be spherical, cylindrical, square tubular, etc.
02
Characteristics of Foam-filled Buoys (Core Advantages of Filled Foam)
The foam-filled buoys / fenders, due to their high elasticity after expansion, ensure high energy absorption and low reaction force. They are entirely made of closed-cell foam, which can guarantee unsinkability even when damaged by breaking, rupturing or shearing after hitting rough vessel sides. Since the material is closed-cell foam, it can prevent water from entering.
03
Polyurea Coating Process (Highlights of Advanced Coating Technology)
The SPUA-coated skin has unsurpassed strength. The skin is wrapped in a helical pattern and integrated into itself. This advanced technological process makes the skin of the foam-filled marine buoys / fenders extremely durable under all weather conditions, external forces and marine environments. Polyurea is spray-applied to the foam-filled marine buoys / fenders, creating a high-quality and homogeneous skin matrix that combines extreme wear resistance, non-marking properties and the option of high-visibility colors.

Marine Mooring Buoy Description
Marine Mooring Buoy
The same construction method used to produce luhang floating foam fenders are used to produce Mooring Buoys. Resilient closed cell polyethylene foam is thermolaminated around a central tubular steel frame forming a flexible, impact resistant flotation core. The foam core is then coated in a high performance elastomer skin and two flanges are welded in position to secure the foam core firmly in place.
Marine Mooring Buoy
