​Introduction:

Following the xanthan gum, gellan gum,welan gum, Diutan gum is a new microbial polysaccharide,which is by microbial fermentation generated water-soluble polymer, it has excellent thickening, pseudoplastic, resistance to high temperature, high salt, and a wide range of pH adaptability, it can be widely used in petroleum industry, construction industry.

Compare to the welan gum, it has

1、Higher viscosity

2、Longer heat stability

3、Better viscosity in salt solution, especial in Ca2+ solution

4、Better Rheology
