회사 뉴스 Tonneau Cover Vinyl Fabric Material Waterproof Fabric Black PVC Leather Grain for Truck Tonneau Cover
This product is specifically designed for pickup truck tonneau covers, featuring a high-density 1000D*1000D polyester base fabric with double-sided PVC coating. The surface undergoes high-temperature and high-pressure embossing to achieve a leather-like texture resembling荔枝纹 or鳄鱼纹. Professional testing data shows a weight of 750gsm, with tensile strength reaching 2500/2700N/5cm in the warp and weft directions respectively, and tear resistance of 400-450N, capable of withstanding cargo vibrations and frequent opening/closing stress. The material boasts a hydrostatic pressure value of ≥3000mmH₂O, ensuring complete waterproofing; a temperature range of -40℃ to +70℃, and maintains over 85% of its tensile strength after passing the QUV 3000-hour aging test. The surface is treated with an ACRYLIC or PVDF nano-coating for self-cleaning and stain resistance, allowing for easy cleaning with rainwater.
1. Core indicators of weight and strength
Priority should be given to products weighing 750gsm or above, ensuring a tear strength of ≥ 400N (ISO 4674) and a tensile strength of ≥ 2500N/5cm (ISO 1421). Below this standard, it is prone to tearing under high-speed wind pressure.
2. Weather resistance and aging resistance
It is necessary to verify the QUV 3000 hour aging test report (ASTM G154), with a tensile strength retention rate greater than 85%, to ensure that it will not become brittle or fade for 3-5 years. The temperature tolerance range should reach -40 ℃ to+70 ℃, suitable for both extreme cold and heat.
3. Surface technology and waterproofing
Choose PVDF or ACRYLIC nano coating surface with a water contact angle of ≥ 110 ° to achieve lotus leaf effect self-cleaning and prevent oil stains from adhering easily. Hydrostatic pressure value ≥ 3000mmH ₂ O (ISO 811) to ensure no leakage in rainstorm. The leather pattern (lychee pattern/crocodile pattern) should be uniform and clear to avoid foaming and delamination during use. Before bulk procurement, sample the fabric and test its tear resistance and coating adhesion.
Q: How about the waterproof effect of this leather textured PVC canvas in rainstorm?
Answer: The waterproof performance is very reliable. After 12 consecutive hours of rainstorm, the container was completely dry, and the hydrostatic pressure value ≥ 3000mmH ₂ O was fully verified. The lotus leaf effect is obvious on the surface, and rainwater forms beads that slide down without leaving any water stains.
Q: Will the material fade or become brittle after long-term sun exposure?
Answer: The performance remains excellent. After two and a half years of use (three summers), the black leather texture has no obvious fading, and the surface has no powdering or cracking. The QUV 3000 hour aging test data is authentic and reliable, with a tensile strength retention rate of over 85%.
Q: What is the tear resistance under frequent opening and closing and friction of goods?
Answer: The performance was very outstanding. It opens and closes 2-3 times a day, with frequent friction when loading goods. After 20 months of use, the measured tear resistance strength still reaches 380N (initial ≥ 400N), with no tear damage. The 750gsm high weight design ensures long-term durability.
