Hydroxypropyl guar gum,China price supplier

guar gum (galactomanan) is a high molecular weight carbohydrate polymer made up of a large number of mannose and galactose unit linked together. the crude guar gum is a grayish white powder 90% of which dissolves in water. it is non ionic polysaccharide based on the milled endosperm of the guar bean whose average composition is hydrocolloid: 23% fats: 40% proteins: 34%.

the most important property of the guar is its ability to hydrate rapidly in cold water to attain a very high viscosity at relatively low concentrations. its specific colloidal nature gives the solution an excellent thickening power which is 6to10 timnes thicker than that obtained from starch . it is stable over a wide range of ph and it also improves the flowability and pumpability of the fluid. it is a superior friction loss reducing agent.
