Polyester fabrics with polyvinyl chloride. Generally we use a woven fabric with polyester base, made of PVC fabrics coated with various polymers to give the material color, strength and waterproof properties. There are many different topcoats applied to PVC fabrics ranging from basic acrylic coatings to highly specialised self-cleaning finishes such as PVDF that extend the life of the fabric. PVC fabrics are described by their final weight in grams per square metre. Many different fabric thicknesses with different life expectancies are available; Generally thicker fabrics have an extended life span. Coloured fabrics are available, but usually only in the lighter acrylics with coating variations.
