Calcium and zinc stabilizers are mainly composed of calcium stearate and zinc stearate. Because calcium stearate, zinc stearate and stearic acid structure similar, more charged calcium ions and zinc ions. How to understand an ion with a charge, the polarity is basically the attraction of the charge. ... Read More
