Redispersible cellulose acetate powder morphology: BASFRecent Research Landscape

Inconsistent film formation and poor rehydration in dry-mix mortars lead to structural failure. These innovations utilize specific spray-drying aids to ensure stable particle morphology and rapid redispersion upon contact with water.

What technical problems is BASF addressing in Redispersible cellulose acetate powder morphology?

Poor low temperature fluidity

(22)evidences

Temperature-dependent viscosity increases and wax crystallization in petroleum products impede transport and application. Stabilizing flow characteristics ensures consistent material performance across varying environmental conditions.

Poor dry powder flowability

(13)evidences

Polymeric dispersions tend to coalesce permanently when water is removed during spray drying. Preventing this loss of redispersibility ensures the powder can return to its original colloidal state in cementitious applications.

Unwanted mechanical vibration and noise

(11)evidences

High surfactant requirements and poor droplet stability in water-based systems lead to phase separation. Reducing surfactant levels while maintaining dispersion integrity prevents formulation failure.

Particle agglomeration in dispersions

(8)evidences

Inconsistent particle distribution and spontaneous clustering prevent uniform material performance. Eliminating these physical instabilities ensures predictable rheology and material homogeneity.
