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.
