This product is made of PP and foaming agent. In the moment of Hot summer’s coming, Rapid water evaporation and water pollution have always been the biggest headaches for Reservoir, aquaculture field.”How to reduce water evaporation and pollution” will become the most important problem. Diamond Floating ball is the ideal product. When this ball is floating on the water, those balls automatically arrange themselves into a close packed formation over 99% of the surface area. This high surface coverage provides an extremely effective barrier and significantly reduces the mass and heat transfer mechanisms operating between the liquid and surrounding environment.Low condutivity results in an extremely effective thermal insulation barrier. It is not  just a ball, but a solution to a problem. Most of our successful installations have resulted from working closely with customers, sharing our ideas and experience and tailoring a solution to meet their specific requirements.
