Frequently Asked Questions

Q: What professional data is used to demonstrate the "tear resistance" feature of the product?
A: Using high-strength polyester base fabric and thickened PVC coating composite, tested by ISO 4674-A trapezoidal tearing method, the longitudinal tear strength is ≥ 1050N and the latitudinal tear strength is ≥ 980N, which is more than 70% higher than ordinary tarpaulin (about 600N/550N). It can effectively resist strong wind tearing and sharp object scratching.
Q: How does the "waterproof" performance perform in the continuous rainstorm environment?
A: Through ISO 811 hydrostatic pressure test, the water resistance value is ≥ 3200mm H ₂ O (ordinary PE tarpaulin is only 1500mm), achieving complete waterproof sealing. The edge is strengthened by high-frequency welding, and the strength at the joint reaches over 90% of the base material, eliminating the risk of leakage.
Q: As a "high-quality" tarpaulin, what data supports its weather resistance?
A: After 1000 hours of UVA-340 xenon lamp aging test, the tensile strength retention rate is as high as 92% (ordinary products<65%), and the outdoor service life is extended by more than 5 years. At the same time, it has passed 200 crack free tests at -40 ℃ low-temperature bending, and is suitable for use throughout the year in extremely cold regions.
