Product Highlights

A lightweight, lower-cost, highly adaptable alternative to legacy materials, you can trust our SUPERBULK cable fillers to:

 • Prevent wicking and water absorption

• Resist acids, alkalies, and mildew

• Generate higher yields than any other natural or synthetic fiber

With complete control over the production process from raw material to finished fiber, we can customize SUPERBULK to your unique specifications, including:

• Custom-matched colors

• Fibrillation levels and fiber diameter/density

• Tensile strength, toughness, and elongation Because SUPERBULK is formed into yarns and tapes, it is much more flexible than piped-in polypropylene foam or beads. Adaptable to almost any application, it can be used alone or in combination with other materials. Often more than 10% lighter than similar products, it can also be easier to work with.
