VISCOSIFIERS

DURAVIS

DURAVIS is a non-ionic, water-soluble biopolymer produced through fermentation.
- Aqueous solutions of DURAVIS exhibit exceptional shear-thinning rheology and good suspending ability.
- Has higher thermal stability, pH stability and tolerance of divalent cations such as Ca2+/Mg2+ compared to other biopolymers.
- Shows much higher thermal stability than Xanthan gum. DURAVIS can be used up to 140 oC (285 oF) whereas Xanthan gum shows a gradual viscosity decrease starting at 70 oC (155 oF).
