The flame retardant performance requires a continuous burning time of ≤ 5 seconds. Wind resistance level ≥ 8. Verify third-party testing reports before bulk procurement. Q: Can this customized inflatable cloth really last a night without collapsing when used in tents due to large temperature differences at night?Answer: The actual test shows that it can withstand quite well. We camped on the dam in October, and the temperature dropped sharply by more than ten degrees at night. In the morning, the air column was still strong and the pressure was stable. There is almost no pressure drop within 24 hours, which is the value of high peel strength (≥ 130N/5cm) and high-frequency heat sealing process. The seams are tightly sealed and will not slowly deflate due to temperature fluctuations.Q: Does the wind shake strongly when it blows? What is the wind resistance?Answer: Not at all. On May Day, we went to the beach and in the middle of the night, there was a strong wind of seven or eight levels. The pole of the traditional tent next to us creaked, and our tent cloth trembled slightly. The air column itself was as stable as a rock. This relies on a high weight base fabric of 760g/㎡ or more, a thickness of 0.7mm, and a fracture strength of ≥ 2500N/5cm for the air column. It is a completely lightweight rigid structure that cannot be shaken by ordinary small winds.Q: Will there be water leakage at the joint when it keeps raining? Will it swell up?Answer: No water leaks. Once it rained rainstorm the next day and night. When I got up in the morning, the bottom of the tent was dry and bright, and there was no water stain at the joints of high-frequency welding. The hydrostatic pressure ≥ 9000mm is almost a hard shell, and the air column itself is waterproof, both inside and outside, which is more than enough to cope with conventional rainstorm.
