Product Details
✓PERFECT PACKING SOLUTION: Umail’s expanding foam for shipping are used to use on an industrial scale for packaging odd shaped products, or oddly shaped items, meters, vases, crafts, and even a fully built PC with GPU installed, pc packing foam. They are great for shipping fragile items.
✓WORK QUICKLY: When you crack “L” symbol it immediately comes in contact with the reactant in the “R” symbol. You have only a few seconds to thoroughly combine the two before the final product bursts through a membrane and fills the envelope, so it's super important that you don't start making the foam and expanding it until you have all the supplies you need right there and you're ready to go. Once you get started, you've only got a short amount of time before the foam hardens and generates mild warmth
✓EASY TO USE: Place foam bag on desk, click “L”, you will hear “peng” sound, then slap “L” and “R” with both hands quickly. Pat about 25 times quickly. Then wait for liquid expand and break through L/R area, and quickly distribute liquid evenly throughout bag. Note: Only simple spreading to all corners of the bag is required here (e.g., follow the video instructions), do not keep spreading, as it will disrupt the foaming process. Once you've done that, you should position your item and gently push it into the expanding foam. In just a few seconds, the foam will harden and form a bespoke mold around your object, providing optimal protection as it envelops even the tiniest components
✓WHAT YOU WILL GET: 8 pcs individually packaged expanding foam packaging bags. We recommend used for box size of 8"x8"x8". Please note that the heat generated when slapping the pc shipping foam bag is normal and it will soon return to room temperature, just like holding a hot cup of coffee.
✓WATCH TUTORIAL: If first time user, watching tutorial or instructional video at listing to get a better understanding of how foam expands and how to apply it properly. This will help ensure a good results and prevent expandable foam from expanding more than intended
✓SHIPPING PC: According to experience, when using expanding foam for pc shipping, please place it in case as soon as bag starts to expand. It will automatically adapt to the shape of computer, providing protection, not wait until bag expanded significantly. Be careful to avoid sharp objects.
