Description
BioXan Welan Gum is a soluble extracellular polysaccharide secreted by alkalogenic bacillus. Because its hydrogen exists between the two glycoside rings on the polymer chain, the viscosity of the solution system increases significantly, which makes it better adhere to the surface of the substance, resulting in a wide range of bridge effect of the whole solution system, thus increasing the yield value and maintaining good cohesiveness of the solution system under static or medium shear force. So, it has excellent thickening, rheology and suspension stability.
