Additive used to raise or control the viscosity without the necessity for major changes in the total solids content. Organic or inorganic, generally considered as being either pseudoplastic or thixotropic in nature. Syn. Rheology modifier, Viscosity modifier

Material added to resin to thicken or increase the viscosity of the resin so it will not flow as readily.

The metallic soap or other material used to combine with oil or other lubricating fluid to make grease.

Also referred to as soap - In terms of bearing lubrication this is the substance used to hold the oil and additives in order for the grease to perform. One of the most common being Lithium.

(1) Any material used to thicken a liquid. (2) An additive used to thicken (increase viscosity) or modify the rheology of a coating.

An ingredient which increases the viscosity of a product.

A substance that gives greases their consistency and holds oil. Thickeners used include: metal soaps for calcium soap grease, lithium soap grease, sodium soap grease, complex greases for aluminum complex greases, barium complex base, sodium complex grease, synthetic, organic or inorganic thickeners for polyurea based greases, gel greases (bentonite, micro-dispersed silicic acids) The grease displays particular characteristics depending on the thickener.

A substance added to a liquid to increase its viscosity.
