Sealock is a large-scale waterproof bag manufacturer with ten years of production experience. It produces a wide range of waterproof bags, styles, good designs, good quality, and 100% waterproof. Sealock generally uses TPU and PVC materials, high-quality waterproof zippers or airtight zippers, and then uses high-frequency voltage to join the waterproof bag. The waterproof bag produced by sealock has the characteristics of no pinholes, no seams, and 100% waterproof.
The characteristics of TPU waterproof bag TPU waterproof bag inherits some characteristics of the material itself. For example:By changing the ratio of each reaction component of TPU, products with different hardness can be obtained, and as the hardness increases, the products still maintain good elasticity and wear resistance.
TPU can be processed by common thermoplastic material processing methods, such as injection molding, extrusion, calendering and so on. At the same time, TPU and certain polymer materials can be processed together to obtain polymer gold with complementary properties.
The glass transition temperature of TPU is relatively low, and it still maintains good elasticity, flexibility and other physical properties at minus 35 degrees. It is resistant to oil, water and mold.The mechanical properties of TPU elastomers mainly include: hardness, tensile strength, compression performance, tear strength, resilience and abrasion resistance, buckling resistance, etc., while the mechanical properties of TPU elastic plastics, in addition to theseIn addition to performance, there are higher shear strength and impact energy.
Sealock generally uses TPU materials to make waterproof bags. Compared with the so-called waterproof bags made of nylon or canvas by general waterproof bag brands, the sealock waterproof bag is simply the best! Waterproof bags made of nylon or canvas are prone to problems such as water leakage, water seepage, peeling, etc. Generally, they cannot withstand the toss of outdoor sports. They only have a symbolic waterproof effect, just like the tofu project. Generally, nylon waterproof bags are not suitable for making computer waterproof bags, mountaineering waterproof bags and other outdoor waterproof equipment. Because once there is a water leak, valuables such as laptops and iPads will be damaged!Some people say that Sealock does not produce waterproof bags, but life-saving bags! why?
Once, there were seven beautiful women riding outdoors, riding hundreds of kilometers in one breath, and all the seven beautiful women shed a stinky sweat. Everyone felt that they were no longer like a lady, but like a "female sweat". ". When they were anxious about this matter, suddenly everyone's eyes lit up, and a clear river appeared in front of everyone. Everyone, look at me, I look at you, and then I looked around and found that there were no other people, only seven women. As a result, everyone took off their clothes and jumped into the river. There was a big cleansing. One hour later, two minutes later, and suddenly a girl shouted for help in the middle of the river. Everyone was shocked because everyone was not. They can swim, everyone just stays by the river, but no one knows when the girl calling for help ran to the middle of the river. In an emergency, I suddenly heard a man yelling: "Catch." Everyone looked back and was stunned. It turned out that the man was Cowboy, and the one that was thrown out was the Sealock waterproof bag.
