Grading

Manufacturers define different grades and qualities of guar gum by the particle size, the viscosity that is generated with a given concentration, and the rate at which that viscosity develops. Coarse-mesh guar gums, will typically — but not always — develop viscosity more slowly. They may achieve a reasonably high viscosity, but will take longer to achieve. On the other hand, they will disperse better than fine-mesh, all conditions being equal. A finer mesh, like a 200 mesh, requires more effort to dissolve.
  Food Applications :

The largest market for guar gum is in the food industry. In the U.S., differing percentages are set for its allowable concentration in various food applications. In Europe, guar gum has EU food additive code E412.
Bakery : 

Increases dough yield, gives greater resiliency, and improves texture and shelf life; in pastry fillings, it prevents "weeping" (syneresis) of the water in the filling, keeping the pastry crust crisp.
Ice Creams :

Prevents quick meltdown , Provides smooth and creamier texture , Prevents formation of ice crystals.
Processed Cheese :

Improve texture and Flavor , Stabilizer
Soups :

Thickner and Stabilizer
Beverages :

Viscosity Controller , improves Body and mouth feel , Improve shelf life.
Industrial applications :
Textile Industries :

As thickener for direct as well as discharge printing , wide range of tailor-made products based on printing styles , types of fabrics and dyes , as well as types of printing machines.
Cosmetics :

As a thickener , As a binder and also to disintegrate compressed tablets. As a mild laxative , soluble dietary Fiber.
Pharmaceutical :

As a thickener , As a binder and also to disintegrate compressed tablets. As a mild laxative , soluble dietary Fiber.
Paper Industries :

Used for improved sheet formation , increased bursting strength , increased fold strength and to get a better finish.
some other industrial field where guar gum is used are :

Explosives industry : as waterproofing agent mixed with ammonium nitrate, nitroglycerin etc.

Hydroseeding : formation of seed bearing "guar tack"
