What is the life jacket material? How to use the life jacket? The life jacket material manufacturer will introduce it.

Life jacket material said that the water rescue life jacket is a kind of clothing that can ensure that drowning people float on the water in a safe state and prevent drowning. The basic function of professional life jackets is to provide buoyancy, which is provided by buoyancy materials. So, do you know what professional life jacket material is?

Life jacket material can be divided into three categories:

1. is a natural fiber, commonly used kapok and cork.

It is a soft high closed-cell foam, commonly used in polyvinyl chloride, polystyrene, polyurethane, polyethylene and so on.

3. Other new buoyancy materials.

Summary of life jacket materials The principle of inflatable life jacket is as follows:

1. Buoyancy material is filled with life jacket, that is, nylon cloth or neoprene is used as fabric, and buoyancy material is filled in the middle.

2. Inflatable life jacket: made of high-strength waterproof material, the principle is similar to inflatable life buoy or swimming ring. Can be divided into automatic inflation or passive inflation. But this kind of life jacket should pay attention to: avoid sharp objects pierced or wear waterproof layer, leakage will cause unimaginable serious consequences.

The life jacket is brightly colored, so that rescuers can find you in the distance; secondly, the life jacket generally has a protective effect, which can protect your body from injury.

The buoyancy loss of life jacket shall be less than 5% after being immersed in water for 24 hours. Life jacket buoyancy material: polyethylene foam.

2. Life jackets for marine operations are suitable for all kinds of personnel working in coastal areas and inland rivers. The buoyancy of the life jacket shall be greater than 75N, and the buoyancy loss of the life jacket shall be less than 5% after being immersed in water for 24 hours. Buoyancy material of life jacket: polyethylene foam.

3. Leisure life jackets: some are also called water sports life jackets. The fabric is made of neoprene composite material, with various colors, fashionable and beautiful.
