A fibrillated fiber product with no water content. This makes it suitable for applications where water is not ideal for processing.
PRIMARY USE: Dry mixing operations for products like friction materials. Its dry nature allows it to blend easily with other materials without introducing moisture.
A fibrillated fiber that is processed into sheet form and retains moisture. Unlike wet pulp, wet lap is not shredded but instead delivered as a semi-continuous sheet.
PRIMARY USE: Ideal for wet mixing operations, such as in filtration and specialty paper applications. The moisture content in the sheets helps with integration in water-based or slurry processes.
Similar in fiber composition to wet lap, wet pulp is a fibrillated fiber that is shredded and retains water.
PRIMARY USE: Also suited for wet mixing operations like filtration and specialty papers, wet pulp’s shredded form allows for easy dispersion in water-based processes and applications that need a high degree of binding
A short-cut fiber processed with crimp, allowing improved interlocking and more bulk.
PRIMARY USE: Also suited for gaskets and stucco applications, where the crimped structure enhances bonding and reinforcement.
A short-cut, straight fiber with no bends or waves, ideal for applications needing reinforcement without added texture.
PRIMARY USE: Also suited for gaskets and stucco applications, where the crimped structure enhances bonding and reinforcement.
CFF V110-1 Fibrillated Fiber (PAN Pulp) – Flagship product, equivalent performance to Aramid at a lower cost.
CPF 200 Series – Economical alternative to CFF V110-1.
CFF V125-1 – Shorter fiber than CFF V110-1.
CPF 400 Series Fibers – Acrylic pulp blended with reinforcing fibers like melamine, fiberglass, carbon, and basalt to prevent balling in dry-mixed formulations.
CFF 111 Series – Wet pulp from standard polymer for friction papers. Products include CFF 106, CFF 111 and CFF 114.
CFF 500 Series – Wet pulp from high modulus, high tenacity second generation polymer for friction papers.
CTF 395 Short Cut Staple Fiber – Cost-effective reinforcement solution from standard polymer with excellent adhesion to phenolic resins.
CTF 525 Short Cut Staple Fiber – High tenacity, high modulus acrylic fiber from second generation polymer engineered to absorb crack energy.
