Guar is a polysaccharide that is in the fields of material engineering for its thickening and stabilizing properties. Guar is studied for its effects on the rheology of various products, where it is used to improve texture and consistency. In material engineering, guar is of interest for its water-retaining capabilities and is in studies to develop biodegradable films and hydrogels. Due to its high molecular weight and non-ionic character, guar is further investigated in the field of enhanced oil recovery, where it is used to increase the viscosity of water injected into oil wells to improve the efficiency of oil extraction. Guar′s role in the paper manufacturing industry is examined, particularly for its use in improving paper strength and providing better fiber bonding.
