Polypropylene Balls :
Polypropylene is
lightweight and an excellent electrical insulator. It has a hard, very
smooth surface that prevents bacteria and resists chemical corrosion.
Spheres float on surface of liquid in open
tank and thereby greatly reduce the exposed liquid surface area - up
to 90%. 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. Polypropylene,
non-toxic and able to withstand continuous working temperatures of 110C (230F) Polypropylene is suitable for use in most known chemicals.
High Density Polyethylene generally suitable as above but with a
continuous working temperature limitation of 80 C. (176 F)
softening point about 110 C (230F). High
density polyethylene has better chemical resistance to certain
compounds like oil, and other hydro-carbons. Also less stress cracking
at low temperatures than polypropylene. Color white translucent except
100 mm, black for outside use. All sizes are blow molded.

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. |
