Professional evaluation data interpretation: Industrial reinforced PVC coated polyester canvas roll

This product adopts a composite process of high-strength polyester base fabric and double-sided PVC coating, specially developed for industrial reinforcement applications. Professional testing data shows that the tensile strength can reach 2900/2630N/5cm in the warp/weft direction (ISO 1421), and the tear strength can reach 460/420N in the warp/weft direction (DIN 53363), effectively resisting mechanical stress in industrial environments. Peel strength ≥ 88N/5cm (DIN 53357), ensuring that the coating does not separate during repeated folding. The material has passed the temperature resistance test from -30 ℃ to+70 ℃ (DIN 53372), with a bending resistance of more than 50000 times (DIN 53359A). Hydrostatic pressure value * * ≥ 3200mm H ₂ O

Industrial reinforced PVC coated polyester canvas roll selection guide

1. Core indicators of strengthened structure
It 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 verification
Confirm 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 selection
Verify 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.
