What are PVC coated fabrics?

Here are the key points explaining PVC coated fabrics:
Core Material: They start with a strong, woven base fabric, typically made from polyester or nylon fibers. This fabric provides the core strength and structure.
Coating Process: This base fabric is then coated on one or both sides with a layer of Polyvinyl Chloride (PVC) plastic. This coating is applied as a liquid or paste and then solidified.
Primary Function: The PVC coating transforms the base fabric. It seals the weave, creates a continuous surface, and acts as a protective barrier.
Waterproof & Weatherproof: The PVC layer makes the fabric completely impermeable to water and provides excellent resistance to rain, snow, and environmental weathering.
Strength & Durability: The combination creates a material significantly stronger and more resistant to tearing, abrasion, and punctures than the base fabric alone. It holds up well to rough handling and demanding conditions.
UV Protection: PVC coatings are formulated to resist degradation from sunlight (UV rays). This prevents the fabric from becoming brittle, cracking, or fading excessively when used outdoors.
Flexibility: Despite its toughness, the coated fabric generally maintains good flexibility, especially important for applications requiring folding, rolling, or draping.
Chemical & Stain Resistance: The PVC surface offers inherent resistance to many common chemicals, oils, greases, and pollutants, making it easier to clean and less prone to staining.
Fire Retardancy: Additives can be incorporated into the PVC coating during manufacturing to make the fabric fire retardant, slowing down ignition and flame spread.
Mildew & Rot Resistance: The PVC coating itself is not a food source for mold or mildew, making the fabric highly resistant to fungal growth and rot, even in damp conditions.
Surface Texture & Finish: The coating process allows for different surface finishes (e.g., smooth, textured, glossy, matte) and colors, affecting grip, appearance, and light reflection.
Versatility: This manufacturing method creates a highly adaptable material. Beyond tarpaulins, it's used for truck side curtains, inflatable structures, protective clothing, tents, awnings, pool liners, and industrial containment.
Distinctive Feel & Properties: PVC coated fabrics have a characteristic smooth, slightly rubbery or plastic feel and are heavier and stiffer than uncoated fabrics, but more flexible than solid PVC sheets.
