What Are Space Blankets Made Of

Space blankets, also known as emergency blankets or Mylar blankets, are lightweight, compact, and versatile sheets of material that are commonly used in emergency situations to provide warmth and protection from the elements. These blankets are made from a unique material that is designed to reflect and retain body heat, making them an essential item for survival in extreme conditions. In this article, we will explore what space blankets are made of, as well as provide expert tips on how to use them effectively in emergency situations.

What Are Space Blankets Made Of?

Space blankets are made from a material called Mylar, which is a type of polyester film that is coated with a metallic layer. This metallic layer is what gives space blankets their reflective properties, allowing them to reflect and retain up to 90% of a person’s body heat. Mylar is a lightweight and durable material that is also waterproof and windproof, making it an ideal choice for emergency blankets.

Expert Tips for Using Space Blankets:

1. Keep a space blanket in your emergency kit: Space blankets are lightweight and compact, making them easy to carry in your backpack or emergency kit. Make sure to pack one or more space blankets in your kit so you are prepared for any emergency situation.

2. Use the shiny side facing inward: When using a space blanket, make sure to have the shiny metallic side facing inward towards your body. This will help to reflect and retain your body heat, keeping you warm in cold conditions.

3. Wrap yourself tightly: To maximize the effectiveness of a space blanket, wrap yourself tightly in the blanket to trap in as much body heat as possible. You can also use tape or rope to secure the blanket in place.

4. Use as a shelter: In addition to providing warmth, space blankets can also be used as a makeshift shelter to protect yourself from the elements. You can use the blanket to create a tent or lean-to structure to shield yourself from wind and rain.

5. Signal for help: The reflective properties of space blankets make them useful for signaling for help in emergency situations. You can use the shiny side of the blanket to reflect sunlight or a flashlight to attract attention from rescuers.

6. Use as a ground cover: Space blankets can also be used as a ground cover to insulate yourself from the cold ground. Simply lay the blanket down before sitting or lying on it to create a barrier between you and the ground.

7. Cut to size: Space blankets are often larger than necessary, so you can cut them to size to make them more manageable. Cut the blanket to fit your body or specific needs, such as using it as a poncho or sleeping bag liner.

8. Keep dry: To maintain the effectiveness of a space blanket, make sure to keep it dry. If the blanket gets wet, it may lose its reflective properties and not provide as much warmth.

9. Practice using a space blanket: Before you find yourself in an emergency situation, practice using a space blanket so you are familiar with how to properly wrap yourself in it and use it for shelter. This will help you be more prepared and efficient during a real emergency.
