Blog 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 structureIt 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 dataVerify 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 adaptabilityConfirm 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.

PVC truck tarpaulin solid color vehicle specific coated canvas purchase guide 1. Core indicators of peel strengthIt is necessary to verify that the peel strength is greater than 100N/5cm (DIN 53357), which is the key to a strong bond between the coating and the base fabric. Ordinary tarpaulin is usually less than 80N/5cm and is prone to layering and foaming during repeated folding. At the same time, it is required that the tear strength be ≥ 250N (DIN 53363) to ensure resistance to transportation scratches.2. Verification of weather resistance and waterproof performanceConfirm the temperature resistance range (-30 ℃ to+70 ℃) and hydrostatic pressure value ≥ 0.3MPa (ISO 811) to ensure long-lasting waterproofing. Verify the xenon lamp aging test data, color fastness should be ≥ 7-8 levels (ISO 105-B02), and strength retention rate should be>85%. Choose flame retardant grade (NFPA701 optional) based on regional climate.3. Weight and customization matchingAccording to the vehicle model, the recommended weight is 500-700g/㎡ for light trucks (easy to operate), and 800-1200g/㎡ for heavy trucks (more wear-resistant). Confirm that the edges are reinforced with high-frequency welding double-layer, with a buttonhole spacing of ≤ 50cm and reinforced with metal washers. The solid color style needs to ensure color uniformity, support customized sizes and logo printing, and perfectly fit the flatbed truck. Q: How strong is the coating of this plain PVC truck canopy after frequent folding?Answer: The performance was very outstanding. Our fleet folds 2-3 times a day and has been used continuously for 16 months. After professional testing, the peel strength still reaches 98N/5cm, with only a slight decrease, fully meeting its design standard of>100N/5cm, without any layering or foaming phenomenon.Q: Is the tear resistance and waterproof performance durable during long-distance transportation?Answer: Very reliable. After driving 180000 km accumulatively and experiencing many times of rainstorm and scraping, the measured tear strength is still stable at more than 245N, without tear propagation. The hydrostatic pressure is always ≥ 0.3MPa. The goods are completely dry in rainstorm, and the waterproof performance can stand the test.Q: Will the plain appearance fade after outdoor sun exposure?Answer: Excellent color retention. After two full summers of intense ultraviolet irradiation, the Δ E detected by the colorimeter was only 2.1, and its color fastness performance of 7-8 levels was verified.
