Biozan is a high molecular weight welan biopolymer used for rheology control in water based systems.
Biozan is sometimes referred to as Welan gum.
Appearance: Cream coloured powder
Bulk Density: 800 kg/m3
Specific Gravity: 1.5
pH: 6-9(1% solution)
High molecular weight
Biozan’s primary function is to provide effective viscosity under varied conditions. Biozan exhibits
superior temperature stability (Over 90 oC) in fresh water, low salt (Chloride less than 50,000 mg/L)
and low pH (Less than 10) fluids. Biozan will perform effectively in high pH, lime treated systems,
cement contaminated muds, glycol based fluids, stiff foams and cationic inhibitive systems where fluid
temperatures are below 90 oC. An oxygen scavenger will improve stability in fluids over 90 oC.
Prolonged temperatures over 165 oC may produce degradation. For cementing applications Biozan can
be used to control free water at elevated temperatures.
MIXING AND HANDLING
Biozan should be added slowly to avoid lumping when adding directly to water. Biozan is a non-
hazardous material and can safely be used in environmentally sensitive areas. For handling and safety
instructions consult Material Safety Data Sheet.
