UV resistant multi-purpose waterproof tarpaulin roll selection guide 1. Core indicators of UV resistance performanceIt is necessary to verify the UV irradiation test report and select products with a UV barrier rate of ≥ 99% and a tensile strength loss of ≤ 5% after 1500 hours of UVB irradiation. Ordinary PE tarpaulin usually does not have UV resistance treatment and will become brittle after 3-6 months.2. Waterproof and weight balanceSelect the hydrostatic pressure value according to the usage scenario: mild coverage should be ≥ 5kPa, and long-term outdoor protection should be ≥ 8kPa. The recommended weight is 190-220g/㎡ (balancing portability and durability), with a weight below 160g/㎡ being easily damaged and above 250g/㎡ being bulky and inconvenient.3. Multi purpose adaptability verificationVerify the tear resistance strength (recommended longitudinal/latitudinal ≥ 100N) and temperature resistance range (-30 ℃ to+70 ℃). Confirm the edge strengthening process (double-layer locking edge+heat sealed seam) and the spacing between buttonholes (≤ 50cm). Choose color according to usage: Dark colors absorb heat but are more resistant to UV, while light colors reflect sunlight but are prone to dirt. Q: What is the actual durability of this UV resistant tarpaulin under long-term exposure to sunlight?Answer: The performance is very reliable. Our outdoor equipment has been covered with this tarpaulin for 28 consecutive months, and after professional testing, its tensile strength has only decreased by 4.8%, fully meeting the commitment of ≤ 5%. The surface is free of powdering and brittle cracks, far exceeding ordinary tarpaulins (which usually age within six months).Q: Is the waterproof effect long-lasting during rainy seasons?Answer: Completely reliable. After experiencing two complete rainy seasons (with a cumulative rainfall of over 2000mm), the static water pressure of the tarpaulin remained stable at above 8.2kPa, and the covering remained dry. The edge heat sealed joint has no leakage, verifying the reliability of the waterproof process.Q: Can tear resistance be used with frequent changes in usage scenarios?Answer: Durable enough. We have repeatedly disassembled and reassembled the tarpaulin over 40 times on construction sites, camping sites, and cargo shelters, and there is no tearing or expansion at the edges and buttonholes of the tarpaulin. After testing, the tear resistance strength still remains above 98N (initial value of 105N), proving its excellent fatigue resistance characteristics.
