welan gum is resistant biopolymer
Source：Release time：2017-02-21 11:13:23
We are a enterprise who dedicates to the research and development, production and sales of biological products.Our mainly products are welan gum,diutan gum and anti-high temperature biopolymers.
welan gum is thermally resistant biopolymer for viscosity for viscosity and suspension control in industrial applications, it is stable up to 300ºF(150ºC)in water-based drilling, workover and completion fluids, with unique features for Lower Shear Rate Viscosity (LSRV) of drilling fluids and divalent ion tolerance
FEATURES
1. High viscosity under low concentration.
2. High viscosity under low rotation.
3. Fine moisture retention.
4. Peculiar stability under high salinity.
5. High temperature resistance.
