Dynarex - Instant Cold Pack is a portable plastic sac that is filled with water and Calcium Ammonium Nitrate. Each instant cold pack contains two bags within the package. The inner bag contains water and the other contains the Calcium Ammonium Nitrate. When the pouch is squeezed and the water is released, it joins the chemicals inside the second bag, creating a chemical reaction the absorbs heat from its surrounding environment and quickly brings the pack to around 32 degrees.
There are many types of cold packs including reusable ice packs, all purpose gel packs, disposable cold packs and instant cold packs. Dynarex instant cold packs can be used for the relief of minor injuries and swelling. These instant ice packs can also be used for sprains, strains, contusions, minor burns, toothaches, nosebleeds, headaches, insect bites, back and body pain and any area of the body that requires a cold compress.
To activate cold pack, squeeze and shake. No planning time is needed. Once the bag is activated, it is ready for use. Each pack can be used for an extended period of time. Cold therapy sessions generally last 15-20 minutes depending on the type of injury.
This product is similar to the ColdStar Instant Cold Pack, which is no longer being offered through the manufacturer.Effective Ice Therapy Tips:
