PVC tarpaulins utilize a high-density polyester fiber base fabric and PVC coating composite process to form a dense waterproof layer, capable of withstanding water pressure exceeding 3000mm without leakage. Whether it's outdoor transportation in heavy rain or a humid and rainy storage environment, PVC tarpaulins can effectively isolate moisture and protect goods from getting wet. For example, actual test data from a logistics company shows that the internal humidity of containers covered with PVC tarpaulins remained below 10% during heavy rain.
The PVC coating gives the tarpaulin superior wear resistance, resisting friction with goods and external damage such as ground scraping during transportation. Its tear strength reaches 1200N/5cm, more than 3 times that of ordinary tarpaulins. On construction sites, PVC tarpaulins are often used to cover easily damaged materials such as rebar and cement, with a tested service life of over 5 years.
PVC tarpaulins can withstand temperature changes from -30℃ to 70℃. They are used in applications such as scientific research tents on the Qinghai-Tibet Plateau and high-temperature transportation covers in the Middle East. Their ultraviolet protection factor (UPF) reaches 50+, and the strength retention rate remains above 80% after 3 years of continuous exposure to sunlight, effectively preventing aging and cracking.
The PVC coating has natural resistance to weak acids, weak bases, and salt spray, with a pH tolerance range of 3-11. Electroplating plants and chemical plants often use PVC tarpaulins to cover equipment to prevent corrosion from pickling solutions and chemicals, extending the service life by more than twice compared to traditional canvas.
PVC tarpaulins are the "all-round protectors" for industrial protection and daily life. From logistics and transportation to agricultural planting, from construction sites to emergency rescue, PVC coated fabrics are constantly expanding their application boundaries through technological innovation.
