What types of outdoor moisture-proof pads are there
1. Inflatable moisture-proof pads
Inflatable moisture-proof pads can also be called air Beds, inflatable moisture-proof pads were first used as water floating pads in China, and later used by some people as moisture-proof pads for camping. Larger, heavier, and more troublesome to inflate and exhaust, so it is an uncommon variety in the outdoor moisture-proof pad family.
2, automatic Inflatable moisture-proof pad
The automatic inflatable moisture-proof pad is a noble of the moisture-proof pad family. It is a high-end product with very good elasticity and is very comfortable to use. The self-inflating moisture-proof pad is filled with a sponge with good compression and expansion. By squeezing the gas in the sponge and closing the gas nozzle, the pad becomes a semi-vacuum state, and the volume will become smaller. Open the air nozzle, under the action of outside air pressure, the sponge will expand, which can automatically suck the air into the cushion, so it is called an automatic inflatable cushion.
3. Closed-cell foam moisture-proof pad
This kind of moisture-proof pad is the most common variety. It is made of high-pressure polyethylene material. Then cut it into sheets of a certain thickness according to different specifications, and it becomes our common moisture-proof pad. This kind of moisture-proof pad is characterized by closed cells and no water absorption. It is usually cut into a thickness of 0.8-1.0 by 45 times foaming, so it is extremely light in weight. Foamed plastic moisture-proof pads are relatively cheap, have low durability, have peculiar smell when they are used for the first time, and are not good for health.
4. Open-cell foam moisture-proof pads
The open-cell foam moisture-proof pads are generally made of expanded polyethylene, and there are many fine particles inside. The air chamber can allow the entry of outside air, forming an insulating layer. Its advantages are enough comfort, light weight, and the price is not expensive. The air chamber inside the open-cell foam pad can restrict the flow of air, which can achieve a good insulation effect. The disadvantage is that it will absorb water, once it touches water, it cannot be used, and it is large in size, not easy to compress, and inconvenient to use, and the isolation effect is not as good as that of closed-cell foam moisture-proof pads.
5. EVA moisture-proof pad
From its name, we can know the material it uses, EVA is also known as pull-back glue, EVA moisture-proof pad and closed Compared with the porous foam moisture-proof pad, it has the characteristics of good elasticity and strong toughness, so the price is also quite different. It nearly doubles the cost of closed-cell foam dampproof pads, but greatly improves comfort and durability. But from its appearance, it is difficult for ordinary consumers to distinguish the difference between the two.
6. XPE moisture-proof pad
XPE moisture-proof pad, also known as semi-porous foam pad, uses ultra-high pressure polyethylene material. Although this material is not as high-grade as pure EVA material, its strength, toughness and tensile strength are much better than closed-cell foam materials, but its water repellency is not as good as closed-cell materials. High temperature rigidity skin treatment to enhance water resistance. This kind of moisture-proof pad processed by skinning not only enhances the aesthetics and water repellency, but also improves the toughness, and because of the grooves of the pattern, the breathable feeling is also better.
How to buy moisture-proof mat products
1. Check the weather
If the weather conditions are stable , there will be no low temperature. The requirements for comfort should be more important than isolation. If you cannot grasp the factors of weather changes, it is a safer choice to choose a moisture-proof pad with high isolation.
2. Look at the comfort level
Different moisture-proof pad products have different comfort levels. Both inflatable and self-inflating moisture-proof pads are very comfortable, and self-inflating moisture-proof pads are more comfortable, lighter, cheaper and warmer than inflatable moisture-proof pads, but they are expensive. The comfort of other moisture-proof pads is similar, and consumers can choose according to their own needs.
3. Look at the weight
The more comfortable moisture-proof pads are usually thicker and heavier. The weight of the moisture-proof mat is bound to be an important factor to consider.
4. Look at the volume
The larger the volume of the moisture-proof pad, the more comfortable it is to sleep
in, but for people who travel long distances, the It is best not to be too large, especially if the backpack has not enough space.
5. Look at the accessory design
Some accessory designs may influence your decision. The thickness is easier to adjust, and the moisture-proof pad combined with the inflatable pillow makes it more comfortable to use. The moisture-proof pad with the textured concave and convex surface can improve the thermal insulation and anti-skid function. Some are designed to conform to the human body. to save space.
