Its environmental performance complies with REACH and RoHS standards. Anti mold PVC solid color truck tarpaulin coated canvas purchase guide 1. Anti mold performance verificationRequest to provide proof of specific bacterial strain anti mold treatment to confirm the antibacterial effect on common molds such as Aspergillus niger and Penicillium. In rainy areas in the south, priority should be given to anti mold enhanced types. Ordinary tarpaulins do not have anti mold treatment and are prone to mold spots during the rainy season.2. Strength and weight matchingSelect specifications based on transportation intensity:Standard type 500-600g/㎡: Tear strength ≥ 280N, suitable for short distance light loadReinforced 650-800g/㎡: Tear strength ≥ 500N, suitable for long-distance heavy loadsIt is necessary to verify that the tensile strength is ≥ 2200N/5cm (ISO 1421) and the peel strength is ≥ 90N/5cm (DIN 53357).3. Weather resistance and safety optionsConfirm the temperature resistance range (-30 ℃ to+70 ℃) and the absence of cracks during low-temperature bending at -20 ℃. Optional UV resistant treatment (QUV 2000 hours) and flame retardant B1 level (EN 13501). Environmental protection requires REACH and RoHS certification to ensure material safety. Before bulk procurement, the sampling cloth was tested for its anti mold and anti tear properties. Q: How does this anti mold tarpaulin perform in the southern rainy season?Answer: The effect is very significant. After using it continuously for 18 months in Guangdong region and experiencing multiple rainy seasons, there is no mold growth on the surface of the tarpaulin. The antibacterial effect of its anti mold treatment on Aspergillus niger and Penicillium has been fully verified, and at the same time, ordinary tarpaulins have been covered with mold spots.Q: What is the tear resistance and waterproof performance during long-distance transportation?Answer: Excellent performance. After driving 160000 km accumulatively and experiencing many rainstorm, the hydrostatic pressure is always stable and the goods are completely dry. The measured tear strength still reached 520N (initial 540N), with no tear damage.Q: Will the plain appearance fade after long-term sun exposure?Answer: The color should be kept good. After two years of use, the tarpaulin showed no significant fading and the vehicle image was neat and tidy. Its UV resistant treatment ensures outdoor durability, while REACH environmental certification ensures material safety and odorlessness.

Blog Professional Evaluation Data Interpretation: Truck Flat Cover Specialized PVC Leather Grain Waterproof Canvas 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. Truck Flat Cover Special PVC Leather Pattern Waterproof Canvas Selection Guide 1. Core indicators of weight and strengthPriority 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 resistanceIt 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 waterproofingChoose 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.
