Many people who often work or travel in the field know the role of first aid blankets. This kind of thin and fragile "aluminum film" can save lives at a critical time. This is mainly because the first-aid Golden & Sliver Emergency Rescue Thermal blanket can effectively preserve 90% of the heat of the human body without diffusion. What is the heat preservation principle of the first aid blanket? The following Baibai safety net Xiaobian will give you a detailed answer.

There are two ways to keep warm：

1. One way is to add a warm layer. The warm layer is generally some fluffy substances. The fluffy air is used to form a non flowing air layer on the object surface. Air itself is a bad conductor of heat, so it can play a certain role in keeping warm. General down and cotton use this way to keep warm.

2. Another way is heat reflective warmth. Use highly reflective materials to reflect heat radiation back. We all know that white clothes are cooler than black clothes because white reflection is stronger than black and can reflect the sun back. The first aid blanket is a combination of these two principles.

It is small and easy to carry. After folding, it is only the size of your palm. When unfolded, it becomes a silver film that can wrap your whole body.

The life blanket is plated with silver and gold aluminum foil on both sides. It is very light, about ten grams.

Seemingly insignificant, but extremely powerful. In low temperature environment, it can keep 80% of its heat from being emitted
