A: In terms of the unit price per purchase, PVC products do offer a certain price advantage. However, when considering the total life-cycle cost and application risks of a project, PP tarps have more significant advantages: First, they carry lower policy risks, as high-end domestic and international engineering projects and foreign trade orders are gradually restricting the use of PVC products, making PP tarps more environmentally compliant; Second, they offer more stable weather resistance, with no issues of coating aging or peeling, resulting in a longer service life; third, they are recyclable, eliminating solid waste disposal costs; fourth, they exhibit excellent corrosion resistance, making them suitable for harsh operating conditions such as exposure to fertilizers, seawater, and chemical media. For short-term, temporary indoor covering applications, options can be flexibly compared and selected; however, for long-term outdoor use, scenarios with strict environmental regulations, or environments involving corrosive media, all-PP tarps offer significantly higher overall cost-effectiveness and reliability.
