BellBloc 68 Non-Woven Cushion Liner Fabric is a hydrophobic polyester (PET) liner designed to protect cushions and foam padding with a lightweight, breathable barrier that resists water, mold, mildew, oil, and stains. Measuring 54-56 inches wide and weighing 2.01 oz., this resilient fabric enhances outdoor upholstery durability by extending foam life and maintaining tensile and tear strength under heat and UV exposure. PFAS-free and water repellent, BellBloc 68 serves as a moisture barrier placed between outer fabric and inner foam, ideal for outdoor cushions and utility applications that require breathable, mildew-resistant protection without sacrificing comfort.
