Cellulose Fibres

Bisley Cellulose Fibres / Fibers are a range of natural cellulose-based fibers that come in various purities, sizes, and whiteness levels. These fibers find applications across different industries, including construction chemicals, road and asphalt, and filtration.

Benefits/Improvements of Construction Chemicals:

Sag resistance: The inclusion of Bisley Cellulose Fibres helps prevent sagging in construction chemicals, ensuring a stable and even application.

Reduced stickiness: These fibers contribute to reducing the stickiness of construction chemicals, making them easier to handle and apply.

Inhibition of micro-cracking: Bisley Cellulose Fibres possess properties that inhibit the formation of micro-cracks in construction materials, enhancing their durability.

Improved workability: The addition of these fibers enhances the workability of construction chemicals, making them more manageable during application.

Extended open time: Bisley Cellulose Fibres help extend the open time of construction chemicals, allowing for a longer working period.

Reduced shrinkage: The presence of these fibers minimizes shrinkage in construction materials, resulting in better dimensional stability.

Typical Applications:

Bisley Cellulose Fibres are commonly used in the following applications within the construction industry:

Tile adhesives
Plasters and stuccos
Repair mortars
WPM (Waterproofing Membranes) and emulsion-based materials
Tile grouts
Paints and coatings
Epoxies
ETICS/EIFS (Exterior Thermal Insulation Composite Systems)
Joint fillers
Renders
Skim coats

With their versatile nature and beneficial properties, Bisley Cellulose Fibres prove to be a valuable addition to construction chemical formulations, offering improved performance and reliability.
