Blog Professional Evaluation Data Interpretation: Double-Sided PVC Thickened Coating Waterproof Fabric This product adopts a composite process of high-density polyester base fabric and double-sided thickened PVC coating, specially designed for heavy-duty protection. According to laboratory destructive testing, its tear resistance strength is ≥ 800N, and its burst strength is ≥ 2500N, far exceeding single-sided coating products. The double-sided coating structure enables the hydrostatic pressure to exceed 10000mm, achieving complete waterproof sealing. According to the xenon lamp aging test (ISO 4892-2), after a cumulative irradiation dose of ≥ 3500KJ/㎡ (simulated outdoor for 12 years), the coating has no powdering or cracking, and the tensile retention rate is>88%. At the same time, through low-temperature bending at -30 ℃ and 100000 bending fatigue tests, it provides ultra long life guarantee for equipment coverage, logistics warehousing and other scenarios. Double sided PVC thickened waterproof cloth selection guide 1. Core structure verificationThe preferred double-sided thickened PVC coating structure ensures full sealing and waterproofing. Request to provide a cross-sectional coating thickness detection chart. Compared with single-sided coating products, double-sided technology can improve wear resistance by more than 50% and eliminate water leakage hazards caused by exposed base fabric.2. Comparison of key performance dataIt is necessary to verify the tear resistance strength (should be ≥ 800N) and hydrostatic pressure value (should be ≥ 10000mm). Ordinary industrial tarpaulin is usually 400-600N/5000mm, and the data difference directly determines the service life under extreme weather or heavy coverage.3. Durability test report Request xenon lamp aging test report, high-quality products have a performance retention rate of>88% after simulating 12 years of outdoor irradiation (≥ 3500KJ/㎡). Simultaneously confirm passing the -30 ℃ low-temperature bending and flexural fatigue test (recommended ≥ 100000 times) to adapt to harsh environments. Q: Is the anti-aging effect of this double-sided coated tarpaulin really obvious under long-term outdoor exposure?Answer: The effect is very outstanding. Our equipment cover has been used outdoors for over three years, and there is no obvious hardening or cracking on the surface of the tarpaulin. After professional instrument testing, its tensile strength retention rate is still close to 90%, far exceeding ordinary single-sided coating products (usually below 70%).Q: Does the double-sided coating design really realize full waterproof in rainstorm environment?Answer: Absolutely achieved. In the recent continuous rainstorm, the hydrostatic pressure value of the tarpaulin has remained stable above 10000 mm, and the interior of the covered equipment has always been dry. Its double-sided sealing structure completely eliminates the common capillary water leakage problem of single-sided coatings.Q: Does frequent friction of heavy machinery cause significant damage to tarpaulins?Answer: The damage is minimal. The tarpaulin comes into contact and rubs against the metal parts of the equipment on a daily basis. After one year of use, there is no exposed base fabric or peeling coating at the worn area. Its actual tear resistance strength still exceeds 780N, verifying the excellent wear resistance of the double-sided coating.

Blog Professional Evaluation Data Interpretation: Camouflage Print Heavy-Duty PVC-Coated Tarpaulin This product is designed for special environments using a high-density polyester base fabric with a reinforced PVC coating process. Laboratory tests show its tear resistance ≥500N and wear resistance exceeding 10,000 cycles (ASTM D3884). The camouflage pattern employs high-fastness ink, with a ΔE≤3 color difference after 500 hours of xenon lamp aging, ensuring long-term outdoor concealment. The material has a hydrostatic pressure rating ≥5000mm, passes -25°C low-temperature bending tests, and remains corrosion-free after 240 hours of continuous salt spray testing, meeting durability and functional requirements for harsh environments. Camouflage printed heavy-duty PVC tarpaulin selection guide 1. Functional printing verificationFocus on checking the weather resistance of the printing. Professional level camouflage printing should provide a xenon lamp aging test report (recommended ≥ 500 hours) to ensure that the color difference Δ E after outdoor use is ≤ 3, and to avoid rapid fading affecting the concealment effect. Ordinary ink printing usually lacks quantitative data and is prone to fading.2. Heavy duty performance core dataIt is necessary to confirm the tear resistance strength (recommended ≥ 500N) and wear resistance times (≥ 10000 revolutions). At the same time, pay attention to the static water pressure value (should be ≥ 5000mm) to ensure complete waterproofing in complex weather conditions. Insufficient data makes it difficult to meet the harsh outdoor environment.3. Environmental adaptability certificationAccording to the usage environment, it is necessary to verify the low-temperature resistance performance (such as no cracks after bending at -25 ℃) and the salt spray resistance test report (recommended to be ≥ 240 hours). For special applications, environmental certification may be required to ensure the safety and harmlessness of materials. Q: Can the pattern color of this camouflage tarpaulin be maintained after long-term use in the wild?Answer: Keep the effect excellent. Our tarpaulin has been continuously used for over 18 months, during which it has experienced strong sun exposure. After comparison, the color difference change Δ E value is still controlled within 3, fully in line with its commitment of Δ E ≤ 3 after 500 hours of xenon lamp aging, and the concealment is still good.Q: As a heavy-duty tarpaulin, how durable is it in harsh weather conditions?Answer: Very reliable. After many times of rainstorm and strong wind, the hydrostatic pressure of the tarpaulin is stable above 5200mm, and the interior is always dry. Its measured tear resistance strength exceeds 520N, successfully resisting tree branch scratching and strong wind pulling, without any structural damage.
