Blog Professional evaluation data interpretation: PVC waterproof and airtight cloth for inflatable boats/tents/castles/fish ponds This product adopts a composite process of 1000D × 1000D high-strength polyester base fabric and double-sided PVC coating, specially designed for multiple scenarios such as inflatable boats, inflatable tents, inflatable castles, and fish pond liners. Professional evaluation data shows that the material's fracture strength in the warp/weft direction can reach 3200/3000N/5cm, tear strength can reach 400/350N, and peel strength can reach 100N/5cm. Water pressure resistance value>2000mm water column, ensuring complete waterproof sealing. The material has a temperature resistance range of -30 ℃ to+70 ℃, a light color fastness of ≥ 6-7 levels, and a bending resistance of>50000 times. In addition, the product has the option of flame retardant B1 level, which complies with REACH and RoHS environmental standards, providing reliable airtightness and structural protection for water and outdoor inflatable equipment. PVC inflatable boat/tent/castle/fish pond fabric selection guide 1. Weight and strength matchingChoose the appropriate weight and fabric density based on the usage scenario:Inflatable boat/fish pond: Choose 650-850g/㎡, 1000D × 1000D base fabric, tear strength ≥ 350NInflatable tent/castle: Choose 850-1100g/㎡, 900-1100gsm is preferred, tear strength ≥ 500NProducts below 600g/㎡ have insufficient pressure bearing capacity and are prone to deformation and damage when inflated.2. Core indicators of airtightness and waterproofingIt is necessary to verify that the joint peel strength is ≥ 130N/5cm (DIN 53357) to ensure that the high-frequency welding seam does not separate during high-frequency inflation and deflation. Require a hydrostatic pressure of ≥ 9000mmH ₂ O to achieve complete waterproof sealing. The working pressure should meet 15-25kPa, and the pressure holding time of the gas column should be ≥ 48 hours.3. Weather resistance and safety certificationConfirm that the temperature resistance range covers -30 ℃ to+70 ℃, and the -40 ℃ specification can be selected for high-altitude areas. Personnel intensive areas (inflatable castles) require B1 level flame retardant certification (EN 13501 or DIN 4102) and self extinguishing upon ignition. Require REACH and RoHS environmental certifications to ensure the safety of children's contact. Q: How long can this PVC fabric hold up at the seams when used on inflatable castles?Answer: I have been using it for more than half a year, inflating and deflating it every day, and the weld seam has not opened at all. The material has high peel strength, and the joint after high-frequency welding is even stronger than the base cloth. A cheaper product purchased by a competitor had a bulging and leaking air after three months. The corners of this store are tightly welded and have excellent waterproof properties.Q: Will the fish pond liner leak when soaked in water for a long time? Will the fish be affected?Answer: Absolutely not. The fish pond has been used for two breeding cycles, and the water level has not dropped at all. The material is 100% waterproof and has extremely low permeability. And it has passed ROHS/REACH environmental certification, does not contain heavy metals, and the fish is completely safe.Q: Will inflatable boats scratch when used in reef areas?Answer: It cannot be scratched, and there are very few scratches. The material has high tear resistance, 1000D high-strength base fabric, and can be easily dragged with beach gravel. The temperature resistance range is -30 ℃ to 70 ℃, and it can withstand exposure to sunlight in summer and freezing in winter.

Blog Professional Evaluation Data Interpretation: Customized Inflatable Tent Structure Using PVC Waterproof Airtight Fabric Professional testing data indicates that the material used in the gas column structure must meet stringent mechanical standards: longitudinal tensile strength ≥2400N/5cm, transverse tensile strength ≥2000N/5cm, ensuring structural stability under pressurized conditions. Peel strength ≥130N/5cm (DIN 53357) guarantees that high-frequency welded seams remain intact during rapid inflation and deflation. The material's temperature tolerance ranges from -30°C to +70°C (DIN 53372), with a wind resistance rating of ≥9 and a hydrostatic pressure resistance of ≥9000mm, ensuring all-weather reliability. The weight is 760-850g/㎡, balancing structural strength with the portability required for rapid deployment. PVC Waterproof and Airtight Fabric Selection Guide for Inflatable Tent Structures 1. Weight and strength matchingThe air column material is the core load-bearing structure of the tent and must meet strict mechanical indicators. According to the procurement technical requirements, the weight of the air column material should be ≥ 760g/㎡, the thickness should be ≥ 0.7mm, the fracture strength should be ≥ 2500N/5cm in the warp direction, and ≥ 2200N/5cm in the weft direction. High quality products available in the market, such as 1000D × 1000D specifications, have a fracture strength of up to 3500N/3300N/5cm and a peel strength of ≥ 130N/5cm to ensure that high-frequency heat sealing seams do not separate.2. Requirements for airtightness and pressure retentionThe working pressure should meet 15-25kPa, the air column pressure holding time should be ≥ 48 hours, and the self standing time for one inflation should be ≥ 7 days. The hydrostatic pressure must be ≥ 25kPa to ensure waterproof sealing.3. Weather resistance and safety certificationThe temperature resistance range should cover -30 ℃ to+70 ℃, and the -50 ℃ specification can be selected for high-altitude areas. 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.
