The Mylar emergency blanket, also known as a space blanket, is a vital component of any survival kit or emergency preparedness plan. Developed in the 1960s by NASA for the US space program, these blankets have been used to retain body heat in extreme cold environments. The Mylar blanket's effectiveness in emergency situations has made it a staple in outdoor enthusiasts' and emergency responders' gear. In this article, we will delve into the history, functionality, and benefits of Mylar emergency blankets, as well as provide practical advice on how to use them effectively.
Key Points
- The Mylar emergency blanket is made of a thin, lightweight material that reflects up to 80% of body heat.
- These blankets are designed to be compact and portable, making them ideal for inclusion in survival kits and emergency packs.
- Mylar blankets have a wide range of applications, including emergency response, outdoor recreation, and military operations.
- Proper use and maintenance of Mylar blankets are crucial to ensure their effectiveness in emergency situations.
- When choosing a Mylar emergency blanket, consider factors such as size, material quality, and durability.
History and Development of Mylar Emergency Blankets
The development of Mylar emergency blankets is closely tied to the US space program. In the early 1960s, NASA engineers were seeking a lightweight, compact material that could retain body heat in extreme cold environments. They discovered that a thin, aluminized Mylar sheet could reflect up to 80% of body heat, making it an ideal material for emergency blankets. The first Mylar emergency blankets were used in the Apollo missions to keep astronauts warm in case of an emergency landing. Since then, these blankets have become a standard component of emergency kits and survival gear.
Functionality and Benefits of Mylar Emergency Blankets
Mylar emergency blankets work by reflecting body heat back to the user, rather than absorbing it like traditional blankets. This is achieved through the use of a thin, aluminized Mylar sheet that is impermeable to wind and water. The blanket’s reflective surface helps to retain body heat, while its compact size and lightweight design make it easy to carry and store. Mylar blankets are also incredibly durable and can withstand extreme temperatures, from -20°C to 40°C (-4°F to 104°F). In addition to their emergency applications, Mylar blankets are also used in outdoor recreation, such as camping and hiking, to provide warmth and protection from the elements.

| Size | typically 150 cm x 200 cm (59 in x 79 in) |
| Temperature Range | -20°C to 40°C (-4°F to 104°F) |
Practical Applications and Tips for Using Mylar Emergency Blankets
Mylar emergency blankets have a wide range of practical applications, from emergency response to outdoor recreation. When using a Mylar blanket, it is essential to follow proper techniques to ensure maximum effectiveness. Here are some tips for using Mylar emergency blankets:
- Wrap the blanket around your body, making sure to cover your head and neck to prevent heat loss.
- Use the blanket in conjunction with other survival gear, such as a sleeping bag or warm clothing, to enhance its effectiveness.
- Avoid touching the blanket's reflective surface, as the oils from your skin can reduce its reflectivity.
- Store the blanket in a dry, cool place to prevent damage and maintain its effectiveness.
Maintenance and Storage of Mylar Emergency Blankets
To ensure the longevity and effectiveness of your Mylar emergency blanket, proper maintenance and storage are crucial. Here are some tips for maintaining and storing your Mylar blanket:
Regularly inspect the blanket for damage, such as tears or punctures, and repair or replace it as needed. Store the blanket in a dry, cool place, away from direct sunlight and moisture. Avoid folding or creasing the blanket, as this can damage the reflective surface. Instead, roll the blanket up and secure it with a rubber band or twist tie.
