Our ComboTherm(Calcium Chloride mixed with Sodium Chloride) is way less expensive than Calcium Chloride on its own, yet it melts in much colder temperatures than rock salt by itself. If you are very concerned about the environment, first, make sure you are ONLY spreading enough ice melt product to melt the ice (over-salting is generally a bigger problem than which product you choose). So we wanted to help you get to know the two materials so you can make a wise choice. We buy and sell in bulk and we try to offer you the best prices in the area. Calcium Chloride Melts Faster. As stated earlier calcium chloride has umpteen number of usage. It is cheap, cheap, cheap. Yes, blending both together gives you some of the benefits of both! We are glad you asked. Eur., USP, FCC, E509, 99-103%, <=0.0001% Al Calcium chloride dihydrate, suitable for cell culture, suitable for insect cell culture, suitable for plant cell culture, >=98% Snow & Ice Salt & Chemicals Unlimited, LLC. Read this ScienceStruck article to know more about calcium chloride. Holy Guacamole, rock salt is cheap. There are times when sodium chloride just won’t cut it. Calcium Chloride is the Nascar of ice melts while Rock Salt is just “Driving Miss Daisy.” Calcium Chloride works fast to pull water in and change the melting point of the water, and so when speed is necessary, Calcium Chloride is hands down your best option. If you are in Maryland, the DC area, or would like a shipment, feel free to give us a call! When we compare the two, you will quickly find, there is no “winner.”  Instead, it is a matter of using the right tool for the job, and sometimes it is a blend of the two materials that provides the maximum benefit. If you are located in Maryland like we are, or in any of the northern states, you know you have to have something on hand for melting ice and snow BEFORE winter starts. Calcium chloride is able to melt ice at the low low temperature of -20°F, which is lower than any other ice melt products. Rock salt only melts down to 20°F, or a full 40°F difference. Sometimes it feels like you need to dump 5 lbs of rock salt on a small patch of ice just to see it melt. Rock Salt is relatively easy to find throughout the world and it is easy/inexpensive to extract for use. It is used on sidewalks and road and also in parking lots where it works as a de-icing agent. Two of the best loved tools to fight winter are Calcium Chloride and Sodium Chloride/Rock Salt. Sodium Chloride is one of the most caustic ice melts out there not only on plants, but on concrete as well. It has a low melting point, which means it can be dissolved at a very low temperature. Snow & Ice Salt & Chemicals Unlimited, LLC is a leading supplier of ice melt, decier and snow removal tools with locations in Bethesda, Silver Spring and Cambridge, Maryland. If you want the best ice melting product out there, definitely choose calcium chloride, you can’t do better. Boiling point - the temperature at which a liquid turns into a gas; Melting point - the … Material Safety Data Sheet Calcium chloride, ACS - 4 - Evaporation Rate: Not available Viscosity: Not available Boiling Point: Not available Freezing/Melting Point: 175°C Decomposition Temperature: Not available Solubility in water: Soluble Specific Gravity/Density: Not available Molecular Formula: CaCl2.2H2O Molecular Weight: 147.01 Section 10 - Stability and Reactivity Solutions of calcium chloride can prevent freezing at temperatures … When the temperature is 20°F or higher, our pocket books say you ought spread only rock salt. environmentally friendly ice melt product, Calcium Chloride vs Calcium Magnesium Acetate. Items purchased online ship the same day if the order is placed before 3pm EST. By reducing the melting point of the water, calcium chloride prevents the formation of ice. This is the reason why rock salt is the primary ice fighting product at homes and on highways, it is the most cost effective way to prevent accidents and injuries during winter events when temperatures stay above 20°F. Now our super hero Calcium Chloride can melt at temperatures that most of the US will never see. Melting points - freezing points - Documents giving melting or freezing point of elements and different kind of chemical species at varying conditions; ... calcium chloride water freezing point density specific heat dynamic viscosity boiling point ; Sponsored Links . Most of the northern states of the US easily dip below 20°F during the winter. The diverse physical and chemical properties of calcium chloride make it a very useful compound for various industries. In the molten salt electrolysis process, either an anhydrous calcium chloride (CaCl 2, 772 °C melting point) or a 15% KCl mixed salt (630 °C melting point) is used. Calcium Chloride can melt the water in lower concentrations meaning you will have to spread a lot less on to get rid of that same patch of ice. Calcium chloride is relatively harmless to plants and soil. And if you just want cheap, yup, sodium chloride (rock salt) is for you my friend. Calcium chloride dihydrate, puriss., meets analytical specification of Ph. Calcium Chloride is the Nascar of ice melts while Rock Salt is just “Driving Miss Daisy.” Calcium Chloride works fast to pull water in and change the melting point of the water, and so when speed is necessary, Calcium Chloride is hands down your best option. Beyond that, choosing Calcium Chloride will be friendlier than rock salt, but definitely review our article on which is the most environmentally friendly ice melt product so you can make the right choice. This application consumes the greatest amount of calcium chloride. As a deicing agent, it is much more effective at lower temperatures than sodium chloride. One such use of calcium chloride is in drying which is why it is regarded as a drying agent. Generally, we would recommend getting the ComboTherm blend, because it is not much more expensive than rock salt, but it is going to melt at those lower temperatures. Not only do you use less of it, but Calcium Chloride does not negatively impact plant life as drastically as Sodium Chloride. Our snow removal customers are usually located in Washington DC, Maryland, Virginia, Delaware, Pennsylvania and West Virginia but ice melt can be shipped in truckloads to anywhere in the United States. You can’t get any cheaper than sodium chloride for cutting through ice and snow. When distributed for this use, it usually takes the form of small, white spheres a few millimeters in diameter, called prills. By depressing the freezing point of water, calcium chloride is used to prevent ice formation and is used to de-ice. It is difficult to prepare pure anhydrous CaCl 2 since it easily absorbs water and is readily hydrolyzed. The value of melting point of this compound is 772°C. We are open 24/7 before, during and after every snow and ice storm.
