Professional Evaluation Data Interpretation: Heavy-Duty 100% Waterproof PVC-Coated Tarpaulin
This product employs a high-strength polyester base fabric combined with a double-sided PVC coating process, specifically designed for harsh industrial environments. Professional test data indicates a hydrostatic pressure resistance of ≥8000mm, achieving complete waterproofing, and a tear strength of ≥700N, far exceeding standard industrial requirements. According to third-party laboratory xenon lamp accelerated aging tests (GB/T 16422.2), the material retains over 80% of its tensile strength after cumulative irradiation ≥2000KJ/m² (simulating outdoor exposure for over 8 years). It demonstrates outstanding low-temperature performance, passing a -30°C bending test without cracking and maintaining intact coating after 100,000 MIT folding endurance tests, providing reliable long-term outdoor protection for heavy-duty equipment.
Heavy duty PVC waterproof tarpaulin selection guide
1. Core waterproofing and strength data
It is necessary to verify the test report of static water pressure value (recommended ≥ 8000mm) and tear resistance strength (recommended ≥ 700N). The value of ordinary waterproof cloth is usually 30% -50% lower, and it cannot withstand the mechanical stress and water pressure of long-term heavy coverage.
2. Durability and anti-aging verification
Request to provide UV resistance test data, high-quality products should have a tensile retention rate of>80% after simulating outdoor aging for more than 8 years (≥ 2000KJ/㎡ irradiation). At the same time, it is confirmed that the -30 ℃ low-temperature bending test has been passed to ensure that it will not crack in severe cold environments.
3. Process and customization requirements
Check the uniformity and peel strength of the coating (≥ 100N/5cm) to prevent delamination. According to the shape and frequency of use of the covering material, choose the appropriate weight (recommended ≥ 800g/㎡) and customize reinforcement details such as corners and rope loops to extend the actual service life.
Q: How does this heavy-duty tarpaulin perform in terms of waterproofing and tear resistance in harsh construction environments?
Answer: The performance was very outstanding. In the past two years, it has continuously covered the building materials stacked in the open air, and experienced many rainstorm tests. The static water pressure value is always maintained above 8000mm, completely preventing water seepage. Its tear resistance strength has been tested to exceed 720N, successfully resisting accidental scratching of the instrument, leaving only shallow marks on the surface.
Q: Is the material still durable after long-term outdoor exposure?
Answer: The durability far exceeds expectations. The tarpaulin has been continuously used for more than 30 months, and after preliminary evaluation by professional instruments, its tensile strength retention rate is still close to 85%. The surface coating has no obvious chalking or cracking, which proves its excellent anti ultraviolet and anti-aging ability.
Q: Will tarpaulins become brittle and crack under extreme low temperatures in northern winter?
Answer: Absolutely not. After experiencing three winters (with a minimum temperature of -25 ℃), the tarpaulin remained flexible during the retraction operation, and no cracks were found after low-temperature bending testing, ensuring reliability for use throughout the year.
