How Does an Emergency Blanket Function?
An alternative can be curved in the shape of foil and can also help to reflect your body heat back towards you, which works just like a Mylar emergency blanket. It helps retain warmth in cold conditions and works as a barrier against wind and water, helping in convection and evaporation. Additionally, the “foil” construction can be helpful in emergencies since it can reflect sunlight over long distances. It is crafted to be compact and lightweight, providing temporary protection during survival.
What is a Mylar Blanket Made Of?
A Mylar blanket, also called an emergency blanket or space blanket, is typically constructed of a thin, flexible layer of polyester film, often aluminized. It is more accurate to say Mylar (DuPont’s trademarked invention of the ’50s) is a film. Mylar is both strong and lightweight. As noted above, the coating serves a purpose. It reflects nearly 97% of radiant heat, essential for retaining body temperature. This property also makes it possible to see these blankets from afar. Hence, the reflective surface can be used for signaling in emergencies.
Mylar blankets are made from stretching P-E-T (Polyethylene Terephthalate) film coated with thin layers of aluminum. While flaking off lint after usage might be possible, the coating guarantees that it is the correct type of tear-resistant and heat-reflective to be durable under regular conditions’ demands. Mylar’s resistance to most environmental factors and its water and windproof properties make the material suitable for various survival situations. Furthermore, the blanket is chemically stable, which renders it useful for the aerospace industry.
The material’s average weight fluctuates from 3 – 5 ounces (85 – 142 grams) per sheet, depending on the thickness and size. Mylar blankets can be folded to a tiny size, making them easy to transport in first aid kits, outdoor survival gear, or emergency preparedness kits. This technology has successfully reduced the risk of hypothermia and greatly improved survivability in harsh conditions.
