摘要

"Material permeable to air and method of making the material permeable to air and coating material for building pervious to air.Air permeable materials comprise a layer of fabric of low elongation and a microporous coating on the same.The coating comprises a crystalline microporous polymer composition and a filler.The materials are suitable for use in various applications including coating property and other methods of construction.Methods of making a material permeable to air comprises coating a layer of fabric extrusion low elongation with a composition comprising a composition of crystalline polymer and a CS to form a coating on the layer of fabric of low elongation and stretch of incremental mode to non braided layer coated to make the coating microporous.
