Professional evaluation data interpretation: PVC coated canvas for roof tents/truck tarpaulins

This product is designed specifically for vehicle mobile protection, using a composite process of high-strength, low elongation polyester base fabric and weather resistant PVC coating. Verified by professional wind tunnel testing, the fabric maintains structural integrity under wind speeds of 120km/h, with no risk of severe shaking or tearing. Hydrostatic pressure value ≥ 6000mm (ISO 811), to ensure that the continuous rainstorm environment is completely waterproof. The material has undergone high and low temperature cycling tests from -30 ℃ to+70 ℃, and is suitable for extreme climates. The dynamic abrasion test (ASTM D4966) showed no damage after 50000 frictions. Excellent UV resistance, with a tensile strength retention rate of over 85% after 1500 hours of xenon lamp aging, providing reliable protection for outdoor use of roof tents and trucks year-round.

Roof Tent/Truck Tent PVC Coated Canvas Selection Guide

1. Dynamic wind resistance and strength verification
It is necessary to verify the wind tunnel test report to ensure the structural integrity of the fabric under the condition of a speed of ≥ 100km/h (high-quality products can reach 120km/h). At the same time, it is required that the tear resistance strength be ≥ 500N to cope with the instantaneous wind pressure and vibration stress during high-speed driving.
2. Climate adaptability indicators
Confirm the temperature resistance range (-30 ℃ to+70 ℃) and the low-temperature bending test report to avoid severe cold embrittlement or high-temperature softening. The anti UV performance requires 1500 hours of xenon lamp aging test data, with a strength retention rate of>85% being optimal.
3. Wear resistance and waterproof grade
Check the wear resistance frequency (recommended ≥ 50000 Martindale cycles) and hydrostatic pressure value (≥ 6000mm). The roof tent needs to withstand baggage friction and rainstorm test, and insufficient data is likely to lead to early damage and leakage. It is also recommended to choose a surface anti slip treatment model to enhance the stability of equipment fixation.

Q: How does this roof tent fabric perform in terms of wind resistance during high-speed driving?
Answer: The performance is very stable. We have driven at speeds of 110-120km/h on the highway multiple times, and the tent fabric has always adhered without any severe shaking. Its actual tear resistance strength still exceeds 520N, proving that the design standard of ≥ 500N is sufficient to cope with long-distance high-speed wind pressure tests.
Q: Will materials age and deform under extreme temperature differences outdoors?
Answer: The durability exceeds expectations. After experiencing a complete annual cycle from -25 ℃ winter to 45 ℃ summer, the tent fabric showed no significant hardening or softening. After instrument evaluation, its tensile strength retention rate is still close to 88%, verifying the reliability of the 1500 hour xenon lamp aging test.
Q: Are the waterproof and wear-resistant properties durable in actual field use?
Answer: Completely reliable. In rainy seasons, camping encounters continuous rainstorm, the hydrostatic pressure of the tent is always stable at more than 6000 mm, and the interior is completely dry. The daily friction between the surface and tree branches, as well as hiking poles, showed no obvious signs of wear, and its 50000 wear resistance standard was fully verified.
