Adult life jacket material and composition

Adult life jacket is a life-saving equipment that can provide buoyancy and protect the lifesavers in the water. Generally by the life jacket outer layer, floating core, straps, mouth spin and other parts of the composition, its material mainly plastic, rubber, nylon, etc.. The following we will introduce in detail about the adult life jacket material and composition of the relevant knowledge.

1. The outer layer of life jackets

The main material of the outer layer of the life jacket is polyvinyl chloride (PVC) plastic material, which is waterproof, moisture-proof, soft and sun-proof, etc. The greater the thickness of the material, the stronger the tear resistance of the life jacket, which enhances the durability and wear resistance of the life jacket. In addition, the outer layer of the life jacket can also choose rubber materials, this material has acid and alkali resistance, weather resistance, anti-aging and other characteristics, its elasticity is good, can effectively prevent the life jacket because of long-term deformation and affect its service life.

2. Floating core

Float core is the key part of the life jacket z, it is used to provide buoyancy of the key components. EPE foam has light, durable, low-cost characteristics, and has a good water absorption performance, not easy to deformation, is the ideal material for making life jacket floating core; and polyurethane foam has better compression and tear resistance, and not easy to absorb water, so the price is higher than EPE material. Higher.

3. Belt

Adult life jacket back belt part need to use high strength, durable performance of the material, generally nylon, synthetic fiber and polyester, etc.. Among them, nylon has a better stretch, can effectively reduce the life jacket for the static and dynamic strength of the lifeguard, while artificial fiber has better resistance to weathering and aging ability.

4. Mouth spin

Mouth spin is a fixed life jacket mask, adjust the size of the life jacket components. It can ensure a close fit between the life jacket and lifeguard, so as to improve the buoyancy and protection of the life jacket in the water. For different life jacket production requirements, generally use different materials and structures. For example, the mouth spin can use high strength metal materials, such as stainless steel, but also more lightweight ABS plastic materials to ensure its good mechanical durability and resistance to wear and tear.

In short, adult life jackets as a kind of equipment to protect the safety of personnel, in terms of material and composition, need to follow the "safe, durable, comfortable, practical" principle, but also need to be customized according to different use scenarios and the user's personal needs, design and production.
