Some materials that work well for outdoor shades include polyethylene, Comtex and polypropylene, notes Lowe's, Arizona Sun Supply, Inc. and Shade Cloth Store. Outdoor shade materials are typically woven or knitted, and most are ultraviolet ray-resistant to withstand the sun's direct rays.
Polyethylene is a UV-stable material, and it is able to withstand high heat for several years, states Lowe's. The Riverside RSI brand offers various percentages of shade with brass grommets for hanging.
Polyfab Comtex is able to withstand natural elements, including dust, UV rays, rain, hail and wind, notes Arizona Sun Supply. Comtex is a knitted shade material.
Polypropylene can be woven or knitted and both types work well in outdoor settings. Woven types have a bit of a plastic look, whereas knitted types look more like fabric, states the Shade Cloth Store.
