Calcium Chloride or Magnesium Chloride?
Salt Industries offers bulk delivery of high quality deicing products that include both calcium chloride and magnesium chloride. But what exactly are the differences, and which one is right for you or your business? There are a few aspects in which these chemical compounds differ which we’ll take a look at below.
Effectiveness at Low Temperatures
The range of temperatures in your area is perhaps the first thing one ought to consider when making a choice of deicing product. Calcium chloride melts ice effectively at temperatures as low as -20 degrees Fahrenheit, while magnesium chloride is effective at as low as -13 degrees. If you’re regularly facing temperatures considerably below -13 degrees, you may wish to go with calcium chloride rather than magnesium chloride.
Potential Environmental Impact
More densely populated or vegetated areas may face concerns with the over-application of a deicing agent. Exposure to too much calcium chloride (or other chloride compounds such as sodium chloride) can be harmful to lawns, other types of vegetation, and animals. Magnesium chloride has been shown to be generally safer than calcium chloride when it comes to protecting your plants or animals. Although somewhat larger quantities of magnesium chloride are necessary for its effective use, it is an environmentally less risky substance.
Though not considered drastically different in level of corrosive potential, research commissioned by the Colorado Department of Transportation has indicated that magnesium chloride may be more harmful to certain metals than its counterpart. Magnesium chloride was shown to be more corrosive than sodium chloride when applied to stainless steel and aluminum, though all chloride based deicing compounds are somewhat corrosive in general. Researching how the two deicers interact with surfaces you may be concerned with protecting from potential corrosion could be a factor to consider in which product is right for you.
Hopefully this review of some of the differences between calcium chloride and magnesium chloride has helped you to determine which product may be right for you.
