Polyurea Thickener – tribos

 · The thickener is created in its most basic form by the reaction of diisocyanate with monoamine. Some of the monoamine may be replaced with diamine, so longer chemical chains will form. Water can be added to the diisocyanate before the monoamine is added; this causes a reaction which forms diamines, so when the monoamine is finally added a wide mixture of different ureas are created.

What is the thickener in lubricating grease?

 · A typical polyurea thickener is the reaction product of a di-isocyanate with mono and/or diamines. The ratios of the ingredients determine the characteristics of the thickener. It should be noted that because polyurea thickeners do not contain any metallic elements, they are ashless and tend to be oxidatively stable.

Polyurea

Polyurea is a type of elastomer that is derived from the reaction product of an isocyanate component and a synthetic resin blend component through step-growth polymerization. The isocyanate can be aromatic or aliphatic in nature. It can be monomer, polymer, or any variant reaction of isocyanates, quasi-prepolymer or a prepolymer.
