WM-PB2.5 Polyethylene Buoy is one of Wealth Marine’s latest design and manufacture. This buoy is made from rotationally moulded, UV-stabilised polyethylene material, with its inner body filled with polystyrene foam and being reinforced with a steel structure.
The required colour pigment is injected into the polyethylene material before the moulding process. This prolongs the surface colour of the buoy without the need for painting. In this modern ‘Aids-to-Navigation’ world, Polyethylene Buoys have the great potential of replacing the conventional steel navigational buoys.
This is because as compared to steel buoys, Polyethylene Buoys are light-weight (easier for installation) and possess anti-fouling properties. Besides, due to its elastic nature, it is absorbent to impact forces and can withstand relatively larger collisions. As such, these buoys are maintenance-free and have longer lifespan. Therefore, Polyethylene Buoy is indeed an ideal ‘floating aids to navigation’.
