Camping, tents, sleeping bags and moisture-proof mats are the three basic equipment for camping. Moisture-proof cushion, also known as "heat insulation cushion", is a cushion to prevent the loss of heat in the body, to prevent moisture from entering the body. The basic functions of moistureproof cushion are: 1. moisture insulation; 2. heat insulation; 3. comfort. Now the commonly used moisture-proof pad is aluminum foil moisture-proof pad, which is made of radiation cross-linked polyethylene foam cotton composite aluminum foil, also known as aluminum foil moisture-proof pad.
Aluminum foil moisture-proof mattress has the advantages of large thickness, can reach 8-12 cm, good moisture-proof effect, comfortable, cheap, and can be used on water; the disadvantage is generally eccentric, not suitable for backpack traveling and long-distance travel, more suitable for driving and carrying, egg groove design, conducive to feather sleeping bag back ventilation and warmth, more suitable for outdoor sports in autumn and winter.
Radiation crosslinking polyethylene foam and aluminium foil are the main materials of aluminium foil moisture-proof pad. It is a new environmental protection packaging material. It consists of low density polyethylene grease (LDPE) which is electronically foamed to produce numerous independent bubbles. It overcomes the shortcomings of fragility, deformation and poor recovery of common foam rubber. It has many advantages such as water-proof and moisture-proof, shock-proof, sound-proof, thermal insulation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance and so on. It also has good chemical resistance. Therefore, the material used in the aluminum foil moisture-proof pad is non-toxic and can be used safely.
When traveling with moistureproof mats, the silver face down can prevent moisture from rising; the black face up, mainly used for skid prevention. At the same time, laying a thin mattress or sleeping bag on the mattress can play the role of insulation.
