Polypropylene Balls
Polypropylene has a hard smooth surface that prevents bacteria and resists chemical corrosion.
An alternative material we offer is high-density polyethylene which has better chemical resistance to certain compounds like oil, and other hydro-carbons. Also less stress cracking at low temperatures than polypropylene.

Spheres float on surface of liquid in open tanks and thereby greatly reduce the exposed liquid surface area - up to 90%. They can dramatically diminish objectionable fumes and odors. Blanket of spheres also insulates heated liquid reducing evaporation and heat requirements. Ideal for plating tanks and similar open tank installations where the liquid surface can be covered with a blanket of spheres without impeding access to the tank for process purposes. Spheres are hollow and will float on any liquid. These are non-toxic and able to withstand continuous working temperatures of 110 C (230°F). Polypropylene is suitable for use in most known chemicals.

| The percentage of area covered by the balls is independent of the ball diameter, being the ratio of a circle to the hexagon which surrounds it. This equates to 91% of the liquid surface area. The frictional contact points ensure that each ball remains stable when subjected to increased liquid or air turbulence. | |||
