By results of the material supplier carried-out laboratory working off the experimental data of ready-to-go
Ø52,4 мм (2”) ball solubility were dependent on temperature. These characteristics reflect dependence of speed of
dissolution of a Ball on environment temperature are also presented on the chart.
