Ultimat^®

Ultimat^® needle-punched nonwovens are manufactured using polypropylene or polyester staple fibers to produce the widest widths and heaviest weights available in many colors. Roll widths are produced up to 25 feet (7.6 m) and weights up to 100 oz/yd² (3,391 g/m²). Ultimat^® is inert to biological degradation and naturally encountered chemicals, alkalies, and acids.

Ultimat^® heavy weight nonwovens provide excellent puncture protection when placed above and below membrane liners in reservoirs and landfill applications.  The wide width greatly reduces the installation costs when compared with typical nonwoven widths.  Ultimat also provides superior separation between finer subgrade soils and typical base course extending the life of roadways. Using various diener staple fibers, Ultimat can be designed for capping application where filtration of specific particle sizes is required.  

Typical application:

• Landfill liner protection
• Membrane protection
• Protective wrapping around buried pipes
• Soil/gravel separation layer
• Ballast/subgrade separation beneath railroad tracks
• Cushion support beneath glass lined tanks
• Roadway concrete bond breakers and other applications

• Heavyweight nonwovens with a unit weight of 8 – 100 oz/yd² (271 -3,391 g/m²)
• Fiber deniers ranges from 4 to 45 dpf
• Needle-punched bonding
• Fiber compositions include: Polypropylene, Polyester, Acrylic, and other special fibers
• Roll width can be produced up to 25 feet (7.6 m)
