Key Benefits & Why Formulators Choose NBE Construction Additives — Cellulose Fiber
5–8× Water Absorption Capacity:
Cellulose fiber absorbs 5 to 8 times its own weight in water, dramatically improving workability, open time, and water retention in cementitious and gypsum products.
Superior Anti-Crack Performance:
The 3D fibre network reinforces the material matrix, distributing stress across millions of fibre points and preventing cracking during application and curing.
Excellent Thermal Insulation:
Fibres improve the thermal insulation properties of insulation mortars and renders, supporting energy-efficient building standards.
Improved Surface Strength:
Enhances the tensile and flexural strength of surface coatings, plasters, and renders.
Better Adhesive Strength:
In tile adhesives and grouting compounds, cellulose fiber improves bond strength and reduces slippage.
Uniform Strength Distribution:
Promotes homogeneous material strength throughout the applied layer.
Easily Dispersible:
Readily disperses in dry mixes and aqueous systems without agglomeration.
Frequently Asked Questions
What does cellulose fiber do in construction materials?
Cellulose fiber in construction materials performs several critical functions: it reinforces the material matrix by creating a three-dimensional fibre network that prevents cracking; it improves workability by absorbing and releasing water, extending open time; it enhances thermal insulation properties of renders and insulation mortars; and it improves surface strength and adhesive bond strength in tile adhesives and grouting compounds.
How does cellulose fiber improve wall putty performance?
In wall putty, cellulose fiber improves workability by retaining water longer during application, allowing more time for levelling and finishing. The fibre network prevents shrinkage cracking during drying and curing, resulting in a smoother, more durable surface finish that requires less sanding and rework.
What concentration of cellulose fiber is used in construction formulations?
Typical addition levels range from 0.1% to 0.5% by weight of the dry formulation, depending on the application. Tile adhesives and plasters generally use 0.1–0.3%, while thermal insulation compounds may use up to 0.5%.
