MegaMelt Halite Crystals is the naturally occurring mineral form of sodium chloride (NaCL).
Sodium chloride melts ice at temperatures down to its eutectic point of -6° F (-21° C). And because the most important variable of a deicer's effectiveness is not air temperature but pavement temperature, rock salt continues to be an effective deicer in many US locations through most of the winter season.
The isometric crystals are extracted from one of the Midwest's richest beds of evaporates. Mechanized mining employs mobile equipment and conveyors to blast, load and move the crystals to the surface. Particles are then crushed and screened to specifications to provide halite crystal's signature melting properties.
