Medium Size
5"x9" Heat Pack
This size measures 5" x
9". This size is still small enough to take with you but
big enough so that it stays warm longer. It is
great to take along for anything from walking the dog to overnight
winter camping. Once you've used it boil it
back to be ready for use again in fifteen minutes. When you need
heat just press the activator button - in seconds the salt crystals will heat
up to 130° F. By comparison most single use heat packs warm up to about 104ºF. So with the Quantum Heat Pack, you
get considerably more heat and it only takes a few seconds. It
is fairly simple chemistry - the aluminum button inside triggers a
reaction with the super-saturated salt and water and the salt
(sodium acetate) start to crystallize. As it does it gives off
heat. It is considered a moist heat and because the heat
pack gets so warm, it is very effective for pain.
