Industrial Cellulose Fibers
Asphalt Crack Filler
Our industrial cellulose fibers are multi-purpose additives capable of meeting a wide range of performance needs in industrial applications. Central Fiber® produces cellulose fibers from recycled newspapers and magazines. As such, they are gray in color and fibrous in form. Central Fiber® supplies cellulose fibers with varying degrees of fineness, from very coarse to very fine, and a range of fiber lengths.
Cellulose fibers are used in many industrial applications including:
Stone mastic asphalt
- Asphalt sealers and crack fillers
- Stone mastic asphalt (SMA)
- Asphalt roof coatings and cements
- General coatings
- Fireproof coatings
- Refractory coatings
- Plaster compounds
- Concrete castings
- Acoustical and sound proofing materials
Asphalt roof coatings
When cellulose fibers are incorporated into a liquid medium, they form a net-like structure which stabilizes fluids, solvents, colloids, and other solids. This network prevents separation and sedimentation of the formulation's components, creating a more uniform, stable mixture.
Incorporating Cellulose Fibers
Cellulose fibers are used at varying levels depending on the desired performance properties, processing conditions, and other components in the formulation which may interact with the fiber either favorably or unfavorably.
When packaged cellulose fibers may be compacted. For optimum results, cellulose fibers should be loosened via mechanical means when they are added in the manufacturing process.
Ideally cellulose fiber should be added at a stage where there is adequate fluid available for it to be fully wetted out.
- If there is an aqueous phase, add cellulose fiber as soon as is practical, preferably before fillers are added.
- If there is surfactant in the formulation, it is recommended to add the surfactant to the water before the fiber is added.
Central Fiber® supplies a range of cellulose fibers to meet many performance requirements. Our cellulose fibers vary in fiber size and coarseness, and in their ability to provide viscosity development, rheology, flow control and oil absorption properties.
Cellulose Fibers Deliver
Central Fiber's® cellulose fibers are proven to be highly cost-effective in delivering a wide range of functional properties including (in alphabetical order):
- Absorbent for oil and water
- Anti-settling properties
- Flow control
- Green strength
- Insulating properties
- Mechanical reinforcing
- Minimizing drain-down
- Minimize shrinkage
- Sag control
- Sound dampening
- Suspension of solids
- Thickening of aqueous and non-aqueous fluids
Cellulose fibers provide the additional benefit of being produced from post-industrial newsprint and magazines. Incorporating cellulose fiber into a formulated product adds to the total recycle content of finished products, and enables manufacturers to promote their products as having higher recycled content.
