Waterproof and fire-retardant PVC fabric is an extremely versatile and useful material for a variety of applications. The core of this material is glass fiber which is coated with a polyvinyl chloride (PVC) paste resin and various chemical additives, and then plasticized at a high temperature. These fabrics offer a variety of functions and can be made in a variety of thicknesses and sizes.
PVC-coated polyester fabric is water-resistant, UV-resistant, tear-resistant, and mildew-resistant. It is available in a variety of colors, weights, and patterns and is ideal for awnings and tarps. It is also available in sizes up to 61 inches, making it suitable for a variety of outdoor applications.
Tents made from this type of fabric should be fitted with a fire-retardant fabric. This material should be of a thickness of 16 to 20 ga. In addition, the fabric should be free of any visible cracks or tears. If a seam in the fabric breaks, it should be repaired or replaced.
A typical PVC-coated polyester tarp can be a bit thicker and heavier than most other types of waterproof tarp. It is still waterproof, does not fray, tear, or rip, and is also durable and abrasion-resistant. It is available as rolls or cut-yards.
