Professional Evaluation Data Interpretation: PVC Airproof Fabric for Tent Inflation Columns:

This product is a core material specifically designed for inflatable tent structures. Professional test data shows its exceptional airtightness performance, maintaining pressure for 24 hours under a working pressure of 60kPa with a pressure drop rate below 1.5%, far exceeding industry standards. The material employs a composite process of high-strength polyester base fabric and high-adhesion PVC coating, achieving a peel strength of ≥100N/5cm to ensure the coating does not delaminate during repeated inflation, deflation, and bending of the air columns. Its fatigue resistance has passed ≥100,000 pulse pressure tests, while retaining flexibility even in -25°C low-temperature environments, providing reliable structural support for various demanding outdoor conditions.

PVC Air-Tight Fabric Guide for Inflatable Tents

1. Core airtightness data
When making a purchase, the primary concern is the airtightness and pressure holding data. Professional grade materials must have a pressure drop rate of ≤ 2% within 24 hours at a standard pressure of 40-60kPa. Suppliers can be requested to provide third-party pressure testing reports, as ordinary waterproof fabrics cannot meet this stringent requirement.
2. Structural strength and durability
Inflatable frames require extremely high material strength. The base fabric should be made of high-strength polyester, with key indicators of longitudinal breaking strength ≥ 5000N/5cm and peel strength ≥ 100N/5cm. Insufficient data can easily lead to coating peeling or air column deformation after long-term use.
3. Weather resistance and fatigue resistance certification
It should be ensured that the material passes the low-temperature bending test (-25 ℃ without cracks) and a pulse fatigue test report of ≥ 100000 times should be provided. This is the key to ensuring the safe life of the air column under the temperature difference between day and night and frequent inflation and deflation, far superior to ordinary mesh without testing.

Q: How does the stability and airtightness of the gas column perform in high-intensity commercial activities?
Answer: Very outstanding. We used it continuously for 7 days at the outdoor music festival, and the air column remained stable. Through actual testing, its 24-hour pressure drop rate has always been below 1.8%, fully meeting its high standard of ≤ 2%, and is still reliable even in environments with a temperature difference of up to 20 ℃ between day and night.
Q: Will frequent inflation and deflation affect material life or cause air leakage?
Answer: The impact is minimal. This quarter, more than 80 rapid inflation and deflation constructions have been completed, and the surface and joints of the air column are intact. The material has passed high-strength fatigue resistance testing and has not experienced any air leakage or coating micro cracking problems caused by repeated deformation.
Q: Is there any data to support durability under extreme weather conditions?
Answer: Experienced strong winds (level 8) and low temperatures (-5 ℃). Under strong winds, there is no abnormal swinging of the air column structure, and the tensile strength retention rate is greater than 95%; Under low temperature conditions, the material has good flexibility, rapid rebound, and no hardening or embrittlement occurs.
