Waterproof Fabrics are those that have been inherently treated in such a manner so that they become resistant to water. They are synthetic fabrics that are laminated or coated with waterproofing materials such as polyvinyl chloride, polyurethane, silicone, elastomers, and wax. Water resistant can be measured by the amount of water entering the fabrics in mm. The weight of this fabric is very light. Azad industries are the maker of these Waterproof Fabrics and sell them at very competitive prices.
