This ball was made by blow molding technology. So this ball has not any cracks.Traditionally, this ball is used in water treatment. When millions of Plastic Hollow ball onto the surface of a liquid, the balls automatically form a liquid covering surface. This covering surface provides an extremely effective barrier and significantly reduces the mass and heat transfer mechanisms operating between the liquid and surrounding environment.
At present, according to scientists’ continuous development and innovation, this balls application will become more wider. Such as prevent birds from landing and nesting on the liquid’s surface and around place,use as a check-valve ball in flow control applications, shock absorption in building field and so on.
