In architectural applications, the coating of PTFE fabrics with other fluoropolymers brings the added benefit of a high degree of variety in shape and function. Make them impermeable to fluids. Weldable. Supple enough for a retractable roof.
Comparable to fluoropolymer-coated PTFE fabric, polyester fabric coated with fluoropolymers is often used in architectural applications. Polyester fabric is less expensive than woven PTFE, but also less resistant to high temperatures, so it is essential to use fluoropolymers for the coating which can be sintered at a comparatively low temperature.
PVDF fabric coated with fluoropolymers is commonly used in architectural applications. The partly-fluorinated woven PVDF is weldable and shows good weatherability and dirt repellence. Coating it with fluoropolymers makes it impermeable to fluids too. Since PVDF fabric is less resistant to high temperatures than PTFE fabric, it is essential to chose fluoropolymers which can be sintered at a comparatively low temperature.
Fluoropolymer-coated aramid fabric is primarily used in industrial applications, e.g. for conveyor belts, due to its high resistance to impact and abrasion damage. Coating with fluoropolymers reduces wear even further, thanks to heightened chemical and temperature resistance as well as enhanced sliding properties.
