HDPE Plastics Balls
High Density Polyethylene Balls 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.
Spheres are hollow and will float on any liquid. No welt or rim on which
chemicals can deposit, and being smooth they ensure a much tighter surface
cover. Polypropylene,
non-toxic and able to withstand continuous working temperatures of 110° C (230°F)
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 (230°F).
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.
