Hydrostatic pressure value * * ≥ 3200mm H ₂ O Industrial reinforced PVC coated polyester canvas roll selection guide 1. Core indicators of strengthened structureIt is necessary to verify that the tensile strength is ≥ 2900/2630N/5cm (ISO 1421) and the tear strength is ≥ 460/420N (DIN 53363). Ordinary industrial canvas usually stretches ≤ 2000N/5cm and tears ≤ 300N, and cannot withstand heavy mechanical stress.2. Peel off and flexural resistance verificationConfirm that the peel strength is ≥ 88N/5cm (DIN 53357) to ensure the coating is firm. The key data is the number of times it can withstand bending>50000 times (DIN 53359A), below which it is prone to fatigue damage during frequent folding. Simultaneously, it is required that the hydrostatic pressure value be ≥ 3200mm H ₂ O (ISO 811).3. Weather resistance and weight selectionVerify the temperature resistance range (-30 ℃ to+70 ℃) and xenon lamp aging test data (strength retention rate>85%). Choose weight based on usage: 650-750g/㎡ is recommended for industrial partitions, and 850-1050g/㎡ is recommended for heavy-duty protection. Edge high-frequency welding reinforcement and buckle metal reinforcement ensure long-term industrial use. Q: What is the tear resistance performance of this industrial reinforced canvas in heavy machinery coverage?Answer: The performance was very outstanding. We have been continuously using mining equipment for 20 months, experiencing frequent mechanical friction. After testing, the tear strength still reached 450N/410N (initial value 460N/420N), with only a slight decrease, effectively resisting the scratching of sharp rocks on site.Q: Will the coating separate after frequent folding and use?Answer: Absolutely not. The tarpaulin has been folded and stored over 60 times, and after regular inspections, the peel strength has remained stable at 86N/5cm or above, without any delamination or foaming. Its performance of over 50000 flexural tests has been practically verified.Q: How does waterproofing and strength maintain after long-term outdoor exposure?Answer: The performance is stable. After two complete summers of strong ultraviolet radiation, the hydrostatic pressure is always stable above 3150mmH ₂ O, and the interior is completely dry in rainstorm. The tensile strength retention rate still reaches 89%, the material is not brittle, and its xenon lamp aging test data is true and reliable.

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.
