This product adopts a composite process of high-strength polyester base fabric and weather resistant PVC coating, specially designed for heavy-duty outdoor protection. Third party laboratory tests have shown that its tear strength in the warp/weft direction can reach 1050N/980N (ISO 4674-A), far exceeding that of ordinary industrial tarpaulins (about 600N/550N), with an improvement of up to 70%. The hydrostatic pressure value is up to 3200mmH ₂ O (ISO 811), which is 113% higher than the traditional PE tarpaulin (1500mm), to ensure that the continuous rainstorm environment is completely waterproof. After 1000 hours of UVA-340 xenon lamp aging test, the tensile strength retention rate reached 92% (ordinary PE only 62%), and the outdoor life was extended by more than 5 years. At the same time, it has passed the -40 ℃ × 200 low-temperature bending test without cracking, adapting to extremely cold environments.
1. Comparison of Tear Strength Core
Be sure to verify the ISO 4674-A trapezoidal tear strength data. Professional grade products must meet the requirements of warp ≥ 1000N and weft ≥ 900N, with a durability improvement of more than 70% compared to ordinary tarpaulins (600N grade), and can resist strong wind tearing and sharp object scratching.
2. Waterproof and anti-aging verification
Request to provide a hydrostatic pressure test report, high-quality products should be ≥ 3000mm H ₂ O (ordinary PE is only 1500mm). Simultaneously verify the aging data of UVA-340 xenon lamp for 1000 hours, and the tensile strength retention rate should be greater than 90% (ordinary products<65%) to ensure an outdoor lifespan of more than 5 years.
3. Low temperature and wear resistance indicators
Confirm passing the -40 ℃ low-temperature bending test (200 times without cracks) based on the climate of the usage area. The recommended wear resistance is ≥ 8000 Taber wear cycles (ASTM D3389), with edges strengthened by high-frequency welding. Attention should also be paid to a weight of ≥ 500g/㎡ to achieve a balance between high strength and portability.
Q: How does this high-quality tarpaulin resist tearing in strong storms?
Answer: The performance was very outstanding. Last year's typhoon season experienced 12 hours of strong winds of level 8, but the measured tear resistance strength of the tarpaulin still reached 1020N, without any tearing or damage. The design standard of longitudinal ≥ 1000N has been fully validated in actual extreme weather conditions.
Q: Will the waterproof performance decrease after long-term outdoor exposure?
Answer: Absolutely not. The tarpaulin has covered outdoor equipment for over two years, and after professional testing, the static water pressure value remains stable at 3100mm H ₂ O or above, far exceeding ordinary tarpaulins (usually dropping below 2000mm after one year). The data of 92% strength retention rate after 1000 hours of xenon lamp aging is true and reliable.
Q: Will the materials become brittle and crack when used in the cold winter in the north?
Answer: Excellent flexibility is maintained. After experiencing three winters (with the lowest temperature being -38 ℃), the tarpaulin showed no low-temperature cracks during frequent folding and folding operations. Its -40 ℃ low-temperature bending test certification was verified on site and remains intact as new to this day.
