Product Application
Guar gum is a galactomannan polysaccharide extracted from leguminous plant seeds, with a chemical composition comparable to locust bean gum. It is distinguished by its exceptional cold-water hydration performance, which enables the formation of aqueous solutions with extremely high viscosity.
Guar gum features versatile applicability across a wide spectrum of industries. In the food industry, it is widely utilized as an ice crystal inhibitor, stabilizer, water retention agent, texture modifier and emulsifying aid to effectively enhance the overall quality and uniform consistency of finished products.
In the oil and gas sector, guar gum acts as a core thickening ingredient for hydraulic fracturing fluids. It functions to boost fluid viscosity and minimize fluid loss throughout operational processes.
