The production of PVC coated tarpaulins involves several key steps designed to ensure optimal performance. Initially, high-strength polyester or nylon yarns are woven into a base fabric. The quality of this fabric is crucial, as it determines the tensile strength and overall durability of the final product. Next, the fabric undergoes a coating process where liquid PVC is applied. Advanced techniques like knife coating or spread coating are used to achieve a uniform layer. The coated fabric is then cured through heating, which solidifies the PVC and creates a strong bond with the fibers. Additives may be included in the PVC mixture to impart specific properties, such as UV stabilizers to prevent sun damage, plasticizers to enhance flexibility, and fire retardants to meet safety standards.
One of the primary advantages of PVC coated tarpaulins is their exceptional durability. The combination of a strong fabric base and a robust PVC coating results in a material capable of withstanding significant mechanical stress. PVC tarpaulins exhibit high tear and tensile strength, essential for heavy-duty truck tarps that experience constant tension and movement. Laboratory tests have demonstrated that these tarpaulins can resist tearing forces exceeding 400 N (Newton), making them suitable for covering large, heavy cargo loads without risk of material failure.
Weather resistance is a critical property for tarpaulins used in transportation. PVC coated tarpaulins provide excellent protection against a range of environmental factors. They are inherently waterproof, preventing moisture ingress that could damage sensitive cargo. The PVC layer acts as a barrier to ultraviolet (UV) radiation, reducing degradation from prolonged sun exposure. Additionally, PVC tarpaulins maintain their flexibility in a wide temperature range, from -30°C to 70°C, ensuring they remain functional in both cold and hot climates. This resilience reduces the risk of cracking or brittleness that could compromise cargo protection.
In industrial applications, exposure to chemicals and fire hazards is a concern. PVC coated tarpaulins exhibit resistance to various chemicals, including acids, alkalis, and solvents, due to the inert nature of PVC. This property is vital when transporting chemical substances or operating in environments where exposure is possible. Moreover, with the addition of fire retardant additives, PVC tarpaulins can meet stringent fire safety standards.
