Professional evaluation data interpretation: heavy-duty outdoor waterproof and durable double coated PVC tarpaulin

This product adopts a composite process of 1100D high-strength polyester base fabric and double-sided PVC coating, specially developed for extreme outdoor environments. According to the actual measurement of the third-party laboratory, its hydrostatic pressure is as high as 3200mmH ₂ O, which is 113% higher than the traditional PE tarpaulin (1500mm), to ensure that the continuous rainstorm environment is completely waterproof. The tear resistance strength in the warp/weft direction reaches 1050N/980N, which is about 70% higher than that of ordinary industrial tarpaulins (600N/550N). After 1000 hours of UVA-340 xenon lamp aging test, the tensile strength retention rate reached 92%, and the outdoor life was extended by more than 5 years. Through -40 ℃ × 200 low-temperature bending tests without cracks, it is suitable for year-round use in extremely cold areas and provides reliable protection for heavy-duty outdoor coverage.

Heavy duty outdoor waterproof and durable double coated PVC tarpaulin selection guide.

1. Verification of dual coating structure
It is necessary to confirm the double-sided PVC thickening coating process and provide a peel strength test report (recommended>100N/5cm). Long term use of single-sided coating products can lead to water leakage from exposed base fabrics, resulting in a lifespan reduction of over 50%.
2. Comparison of core performance data
Verify that the hydrostatic pressure value is ≥ 3200mm H ₂ O (ISO 811) to ensure complete waterproofing. The tear resistance strength should be ≥ 1000N/900N (warp/weft direction), which doubles the durability of ordinary tarpaulins (400-600N). Require a strength retention rate of>90% after 1000 hours of xenon lamp aging test.
3. Extreme environmental adaptability
Confirm that it has passed the -40 ℃ low-temperature bending test (200 times without cracks) and is suitable for cold regions. Choose weight based on usage: For heavy-duty coverage, it is recommended to use 800-1000g/㎡. The edges are reinforced with high-frequency welding and double-layer strengthening. The distance between the buckle holes is ≤ 50cm, and metal washers are used for reinforcement to ensure a service life of more than 10 years.

Q: How does this double coated tarpaulin resist tearing in extreme weather conditions?
Answer: The performance was very outstanding. Last year's typhoon season experienced 12 consecutive hours of 10 level winds, but the measured tear resistance strength of the tarpaulin still reached 1020N/950N (warp/weft direction) without any tearing or damage. Its design standard of ≥ 1000N/900N has been fully verified in extreme environments.
Q: Will the waterproof performance decrease after long-term outdoor exposure?
Answer: Absolutely not. The tarpaulin has covered outdoor equipment for over 3 years, and after professional testing, the static water pressure value remains stable at 3100mm H ₂ O or above, far exceeding that of ordinary tarpaulins (usually dropping below 2000mm after 2 years). The data of 92% strength retention rate after 1000 hours of xenon lamp aging test is true and reliable.
Q: Will materials become brittle and crack during the harsh winter in the north?
Answer: Excellent flexibility is maintained. After experiencing three winters (with the lowest temperature being -38 ℃), the tarpaulin has no low-temperature cracks during frequent folding and folding operations. Its -40 ℃ low-temperature bending test certification is completely consistent with its actual performance, and it is still in good condition.
