Automatic Reusable Heating Pad
Reusable Heating Pads that use Exothermic Sodium Acetate Reaction to create heat.
Note: Photos shows several but you order them individually in the size selector box above. Use the selector pull down above to choose a size , then enter the quantity that you desire.
Essentially these are automatic hot water bottles. Chemical reaction provides heat. These are amazing. The first time you see or use one, it is like magic. Especially when you learn they are reusable. The chemical reaction can be reset and these can be used over and over again.
This hot water bottle style - heating pad does not need electricity, wires, batteries, dangerous chemicals, fuel, or require you to add boiling water. It can't cause a fire, electrocute you or poison you - it is very safe.
You get immediate heat with a click of the ferrous metal activator disc inside. You immediately see the crystaline transformation - the exothermic chemical reaction - and then these pads provide soothing heat for aching muscles. They are also reusable - they can be reset and reused over and over again. Just think, on the trail you will always have a heating pad, ready for use, in your kit.
You get anytime, anywhere heat with this Automatic Reusable Exothermic Heat Pad. Made from hospital grade plastic, these are extremely durable.

Exothermic reaction heating pads - Instructions for Use:
To use: In its ready state it feels and acts like a bag of water. Inside you will see a free floating activator disk (looks like a Life Saver candy). Pinch the top and bottom of the activator disk through the bag (like holding the Life Saver by the hole). This initiates an instantaneous chemical reaction. You will see the crystalizing action spreading through the solution - like magic. Massage the bag for a few seconds to make sure the reaction spreads evenly across. The reaction causes the contents to warm up to between 115 and 130 degrees. The heat lasts for about 1 hour. No electricity, no batteries, no dangerous chemicals, no boiling water needed - instant heat relief on the trail. It's similar to using a home hot water bottle.
A big plus with this product --- it is not a one time use product. It can be reset and reused a countless number of times. No waste.
Not only great on the trail - you can use them at home, in your office or school's sports medical kit, disaster survival kits, or for everyday aches and pains.
We stock a couple handy compact sizes. The 3" x 5" is useful as a hand warmer or for the knocks and bumps one might suffer. The 5" x 9" is suitable for lower back, ankle, wrist or knee injury & pain. The 5" x 9" model is flexible and can be used as a wrap.
Instructions for use are printed on the pack. These are non toxic and are made in the USA.
The packs warm to between 115 and 130 degrees Fahrenheit and stay warm for about 1 hour. Eventually they will cool and change to a white crystaline state.
The reset process is imprinted on each pack. Reset is simple and can be peformed an unlimited number of times:
1.) Bring a pot of water to a roiling boil with a wash cloth or similar piece of material inside the pot. The cloth should be positioned to keep the food grade plastic from touching the metal bottom or sides of the pot.
2.) Insert pack and boil for 10 - 20 minutes (directions on pack) to dissolve all crystals inside, which returns them to a liquid state.
3.) Turn off heat source, leave pack in water. Be patient and let the water and pack cool to ambient room temperature.
After a proper reset the contents of the pack will be in a clear liquid state with no crystals inside. You can store it in this state until you need it. To reactivate heat, squeeze the activator disk inside and you will see the chemical reaction start again.
Dimensions and Weight:
* 3" x 5" x 1" = 6.2 ounces
* 5" x 9" x 1" = 13.6 ounces
Technical Information about the exothermic reaction in these heating pads:
The process the heat pack goes through is known as an exothermic reaction. An exothermic reaction is a chemical reaction that releases energy in the form of light or heat. The sodium acetate inside the heat pack freezes at 130 degrees farenheit, but will stay in a liquid state at room temperature. This is known as being super-cooled. With a click of the activator button, you cause a few of the molecules to become solid thus triggering a chain reaction. In the process of going from a liquid to a solid, the by-product is heat. Bending the metal disk starts the crystallization process, and you can see the crystallization proceed through the liquid.
What is happening here seems like magic, but the process can be understood if you think about water freezing. Water freezes at 32 F. If you were to stick a thermometer in a cup of water and put the cup in the freezer, you would find that the temperature of the water falls to 32 F and then hangs there until all of the water is completely frozen. Then the temperature of the solid water falls to the temperature of the freezer. What if you could somehow super-cool the water? That is, say that you could get the water's temperature to 10 degrees farenheit, below the freezing point without it crystallizing into a solid -- you can sometimes do this using a very clean glass and distilled water so there are no points for the water to begin crystallizing. In this condition, if you tap the glass the temperature of the water near where you tap will jump up to 32 degrees, and the water will solidify quickly.
These heat packs contain sodium acetate and water. Sodium acetate is the sodium salt of acetic acid. It is the primary flavoring in salt and vinegar potato chips. Sodium acetate is very good at super-cooling. It freezes (solidifies) at 130 F , but will remain as a liquid at a much lower temperature and is very stable. Clicking the disk, however, forces a few molecules to flip to the solid state, and the rest of the liquid then rushes to solidify as well. The temperature of the solidifying liquid jumps up to 130 F during this process.
When you boil the solidified packs (reactivation process for the packs), you melt it back to the liquid state. You have to completely melt every crystal, by the way, or the liquid will quickly re-solidify. You can repeat this cycle forever, theoretically, just as you can freeze and melt water as many times as you like.
* Do not microwave
* We offer optional custom logos and printing on the product. These make a great unique promotional item because people keep them and reuse them. There is a one time fee of $250 to setup and digitize your master logo, and we require a minimum quantity of 100 units for custom print runs. We will keep a master on file so future orders would not require the setup fee. Custom orders require up to 2 weeks to complete.
These are also useful for:
* Massage Therapy
* Physical Therapy
* Scuba Diving (the will heat under water)
* Cross Country or Downhill Skiing
* Snowmobile Trips and Ice Fishing
* For Fans at Sporting Events
