The permeability of airbag fabrics is one of the most important factors influencing the performance and safety of the airbag.

This review summarizes the structure, principal and several manufacture theories of waterproof and breathable polyurethane film, coating, and their applications.

Covered fabric is less breathable for the covering film is composed with macromolecule material, which prevents the air from premeating between the two sides of the fabric.

The system is mainly composed of external wall,which is made up of inorganic non-flammable exterior thermal insulation mortar, matching interface mortar,float work mortar,scrim cloth,and breathable interior thermal insulation mortar which is developed suing desulfurized waste slag from coal fired power plant and has the function of leveling blanket and thermal insulation layer.
