DuPont™ Spunbond Polypropylene is a nonwoven fabric composed of thermally bonded, continuous polypropylene filaments. The structure gives it good filtration properties and tensile strength even in diagonal direction. In addition, it is made of 100% polypropylene, which makes it resistant to moisture and chemical attack. It is a unique composite media that combines polymer technology with DuPont nonwoven manufacturing expertise. The polypropylene based material is an exceptionally strong yet light, pleatable material with excellent drainage and permeability properties. It is manufactured by a unique integrated process in which continuous filaments of polypropylene are spun and then immediately formed into a multi directional arranged web that is heatbonded at filament crossover points. DuPont™ Spunbond Polypropylene filtration media are harmless to your health and do not pollute the environment, neither in production nor in use. Because the DuPont™ Spunbond Polypropylene media are made of 100% polypropylene, with no binders or fillers, they can be easily recycled.
