Q: What does a Mylar blanket do?
A: The space blanket (depending on the function, also known as a Mylar blanket, emergency blanket, first aid blanket, safety blanket, thermal blanket, weather blanket, heat sheet, or commonly referred to as shock blankets) is an especially low-weight, low-bulk blanket made of heat-reflective thin plastic sheeting. They are used on the exterior surfaces of spacecraft for thermal control, as well as by people. Their design reduces the heat loss in a person's body, which would otherwise occur due to thermal radiation, water evaporation, or convection.
Q: Can you reuse emergency blankets?
A: Yes, this mylar blanket is reusable.
Q: How long do the emergency blankets last?
A: Our emergency space blankets are intended to be disposable, but many people use them repeatedly. How long they last depend on how you're using them.Under normal usage situations, for staying warm while camping or for use during disaster training exercises, the blankets will last for many outings. While they can last a good while and are re-usable, folding them to fit back into their original zippered bag is a skill to be practiced, but perhaps never mastered!
