How about the self-inflating moisture-proof pad
The self-inflating moisture-proof pad is a high-grade moisture-proof pad, which is made of sponge and compression bag. Resilience, it feels like a Simmons in the family. The self-inflating moisture-proof pad is very convenient to use in the field. When not in use, it is in a vacuum state and has a small volume. If you want to use the self-inflating cushion, you can directly open the air nozzle, the air-inflating cushion will automatically enter the air, the sponge in the self-inflating cushion will start to expand, and you can use it.
The self-inflating moisture-proof pad does not need to be blown by mouth, and its filling material has a high resilience, which will not cause the pad to become soft, and has a good thermal insulation effect. This type of moisture-proof pad is divided into high, medium and low grades due to different materials, but no matter which grade, its weight, price and volume are relatively high, and consumers can choose according to actual needs.
< strong>How to choose an automatic inflatable moisture-proof pad
1. Look at the material of the fabric
Low-grade polyester silk with PVC coating is generally used, so the quality will reach more than 1 kg. Medium and high-grade polyester silk is often used with PU coating, and the inner core is made of high-quality sponge, so the compression and toughness are very good. The bonding method can be divided into three methods: edge sealing, semi-bonding and full bonding. The high-end products are all treated with a fully bonded method. After the air is inflated, the cushions appear seamless, so the comfort is very good.
2. Look at the production process
This kind of moisture-proof mat is generally larger in size. In order to reduce the size of the mat, it will be produced by a special production process. There are three kinds of PVC high-frequency welding process, PVC gluing lamination process, and TPU hot-melt full lamination process. Some varieties on the market will dig out the inside of the sponge into a honeycomb shape. When it is strongly compressed, the volume will be greatly reduced, and the weight can be controlled at about 700 grams. However, due to the complicated process, the price will be higher.
3. Look at the quality of the sponge
The indicators of sponge quality include density, porosity, rebound percentage, fatigue resistance, etc. The general sponge density is Between 16-25kg/m3, higher density is the basic factor to ensure rebound. However, advanced foaming technology can make a higher rebound rate under the same density, such as a sponge with a higher opening rate. As the density decreases, the rebound rate, fatigue resistance and other indicators also decrease accordingly, so it is difficult for the self-filling pad made of lightweight sponge to rebound quickly after long-term compression.
4. Air nozzles
There are usually two types of automatic inflatable moisture-proof pads: plastic air nozzles and metal air nozzles, both of which have their own advantages. From a firm point of view, the impact resistance of the plastic valve is also sufficient. Moreover, compared with metal air nozzles, the weight advantage is very obvious, and the shape design is also varied, but its inability to withstand high cold is its fatal weakness, so it is generally used in leisure and non-extreme outdoor sports.
5. Look at after-sales service
Before deciding to buy an automatic inflatable moisture-proof pad, there are still some things you need to consider, that is, the accessories and After sale. Since the self-filling pad is often used in complex environments such as the wild, it will inevitably be damaged. Rich and meticulous after-sales service is very important.
