Cellulose fibers under the Fibrilva brand are versatile additives made from sustainable sources with biodegradable properties. They perform critical functions such as crack control, rheological balance, mechanical strength, and stabilization in water-based systems, ensuring high performance in construction chemicals, paints, adhesives, bituminous systems, and composite applications.
Our fiber portfolio includes various types differing in length, thickness, and structure, offering solutions tailored to a wide range of formulation needs. This ensures both ease of application and reliable, flexible performance in the final product.
Fibrilva cellulose fibers combine sustainability and performance with eco-friendly content and functional strength in modern material technologies.

Its three‑dimensional fiber network reinforces formulations; improves crack control, flexural and tensile strength.
High water‑retention helps maintain moisture balance, control setting time, and improve workability.
Its fibrous form balances viscosity, prevents settling and phase separation, and enhances shelf and application stability.
It mixes easily in dry systems and does not cause clumping; its dispersion ability allows fast and efficient use in production lines.
Derived from a renewable source; eco‑friendly.
