No matter what season, when traveling outdoors, there will always be times when God is unhappy. Give you a chill from head to toe. At this time, if you have a waterproof outdoor backpack
, you want to protect your personal documents, money, and communication tools, and you need to replace the clothes to avoid getting wet. I believe that as a person who loves outdoor sports, I know very well that even if a waterproof bag is not used, a small waterproof bag should be prepared to store money, mobile phones, documents, etc. Having said that, you must doubt that the waterproof bag really has such a good waterproof function, can it protect the contents of the bag from getting wet? The waterproof bags
on the market are all made of TPU waterproof fabric. TPU is the abbreviation of Thermoplastic Urethane, and the Chinese name is thermoplastic polyurethane elastomer. TPU is made of diphenylmethane diisocyanate or toluene diisocyanate, diisocyanate molecules, macromolecular polyols, and low-molecular polyols. Polymer Materials. Its molecular structure is a rigid block obtained by reacting diphenylmethane diisocyanate or toluene diisocyanate with a chain extender, as well as diphenylmethane diisocyanate or toluene diisocyanate. Diisocyanate molecules and macromolecular polyols are alternately composed of flexible chain segments obtained by reaction. TPU has excellent high-tension, high-tension, toughness and aging resistance characteristics, is a mature environmental protection material. At present, TPU has been widely used in medical and health, electronic appliances, industry and sports, etc. It has the characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, and weather resistance that other plastic materials cannot match. . At the same time, it has many excellent functions such as high waterproof and moisture permeability, windproof, coldproof, antibacterial, mildewproof, warmth, UV resistance and energy release. Because ordinary backpack fabrics must have quite poor waterproof performance, even if a glass of water is sprinkled on it, it will seep in. So I suggest that you choose a professional waterproof backpack manufacturer if you are outdoors! For example, a manufacturer! With the development of fashion and fashion, the role of luggage in daily life is constantly improving. For many people, backpacks are a must-have item for travel. Whether on outings or shopping or traveling on business, backpacks are often indispensable. If you have outdoor backpack waterproof customization needs, please look for it, we will provide you with the most professional luggage customization service!
