Hand warmer gloves are grouped into five big categories. The traditional type are pocket sized, composed of metal, with holes in the upper half, and resembling cigarette lights. These types are kept in pouches inside your jacket pockets. These are not the type you can fit into your gloves though..So which type of hand warmer gloves will suit you? Read below to find out.
Traditional Types
1. The traditional hand warmers will apply the slow oxidation of lighter fluid by means of a catalyst. 24 hours of heat can be provide, yet it only consumes as little as a half-ounce of lighter fluid. There is little odor and no flame. Heating the catalyst with a lighter initiates the reaction. It will continue to provide heat until the catalyst is removed until fuel is depleted..
Electric Hand Warmer
2. Using resistive heaters and rechargeable batteries is how an electric hand warmer functions.the reusability of these units is outstanding.
Chemical Hand Warmers
3. One type of disposable chemical hand warmer gloves are fueled by the slow oxidation of iron. Another type involves supersaturation, which is the property of dissolving more than a healthy measure of a substance.
Iron-Based Chemical Hand Warmer
4. These hand warmer gloves contain activated carbon, iron, vermiculite and salt. The contents are exposed to the air when the container is opened, thus exposing Iron oxidizes fairly quickly, generating warmth. These types of warmers are generally only good for one use, but are handily packaged so they can be put in boots, gloves, attached to underwear, and such. These are generally considered to be the #1 for hand warmer gloves, or for putting inside your gloves to keep your hands warm.
The acetate type
5. Sodium triacetate and water in a plastic pocket is submerged in boiling water until all the triacetate dissolves. The solution in the pouch is ends up supersaturated after it is cooled. Then by pressing a small metal tab, this releases a few nuclei, which will force crystallization of extra triacetate, releasing warmth.
So now that you have read about the different types, you should carefully consider what you need. Think about your activities, and how you intend to use your hand warmer gloves.
