What is Blended Ice Melt and How Does it work?

Ice melt blends are popular because they are economically priced while maintaining the ability to work quickly at extremely low temperatures.  Typical blended ice melt contains a combination of sodium chloride, magnesium chloride or calcium chloride.  These chlorides work in different ways to melt ice and snow.blended ice melt - cope performance blend bag

Each of these chlorides has positive and negative attributes.  Sodium is inexpensive and has a long melting duration but does not perform well below 15 degrees.  Magnesium works fast but it is expensive and has a short melting duration.  Calcium is effective down to -25 degrees and melts fast but it is expensive with a short melting duration.  A blended ice melt is formulated to maximize the benefits of each additive.

The formation of an ice melting brine is integral to melting ice and snow.  All three chlorides are either endothermic or exothermic which determines how the brine is formed.  Endothermic ice melt must draw heat from surroundings to dissolve and form an ice-melting brine by lowering the melting temperature of snow and ice.  Sodium is endothermic.  Exothermic ice melt releases heat forming a faster ice melting brine.  Calcium and magnesium are exothermic.

Blended ice Melt from Cope Salt – Cope Performance Blend

Cope Performance Blend (CPB) is Cope Salt’s proprietary ice melt blend specifically designed for the Mid Atlantic region.  CPB contains calcium and magnesium which jump-start the melting process.  The calcium in CPB drills through frozen precipitation and starts melting the bond between the ground and ice and snow.  The magnesium in CPB draws in moisture as it starts to melt.  That moisture helps the sodium in CPB start working and continues the melting process for a longer period of time.  CPB takes advantage of the greatest properties of each ice melt to make an effective blend that works in the lowest temperatures at a reasonable price.  Buy some now!

Why & How Does Salt Melt Ice?

Why Does Salt Melt Ice

Salt is the primary ingredient in most ice melt products because it lowers the freezing point of water.  This is referred to as “freezing point depression.”  In its pure state, water freezes at 32°F.  Even though it may not be visible, molecular water is always present on the surface of ice. When salt comes in contact with water, it starts to dissolve creating a solution referred to as brine which subsequently lowers the freezing point and melts the ice around it. Continue reading

Study Shows Environmental Road Salting Proves Effective

For Immediate Release: April 14, 2017, by the Salt Institute

Naples, FL- A new study published in the Proceedings of the Natural Academy of the Sciences (Salting our freshwater lakes) purports to sound the alarm about rising chloride levels in North American lakes. The study actually found that chloride levels in the majority of the examined lakes either stayed the same or declined and that chloride levels were far below EPA toxicity standards. Chloride concentrations across all 371 lakes in the study had a median of 6 milligrams per liter, while the EPA standard is 230 mg/L.  Continue reading
