复合磺酸钙 CHEMTURA G2087, NLGI No.1/2

DESCRIPTIONG-2087is a member of a family of technologically advanced greases which have been developed by complexing modified overbased calcium sulfonates. This technology, developed and patented by Crompton, is characterized by exceptional mechanical stability, high dropping point, high load carrying performance, reduced wear, and excellent resistance to water and corrosion. This technology equals and in many ways outperforms other premium, high temperature greases such as Lithium Complex, Aluminum Complex and Polyurea.

FEATURES AND BENEFITSThermal and Mechanical Stability

• Superior mechanical stability versus other thickeners, particularly in the presence of heat and water

• High dropping point, typically in excess of 300oC

Load Carrying & Wear Protection

• Excellent EP and AW properties inherent in the thickener

• Does not require the use of additional additives

Resistance to Water

• Excellent resistance to water washout

Corrosion Resistance

• Sulfonates are known and used for their excellent rust prevention properties

• This property is inherent in the thickener

• Will easily outperform all other technologies

Resistance to Oxidation

• The use of premium antioxidant and a high viscosity PAO ensures excellent thermal and oxidation stability

• Bearing life performance in excess of 280 hours

APPLICATION AREASG-2087is a high viscosity synthetic formulation designed to provide superior performance at elevated temperatures and during periods of infrequent lubrication. It is best suited for low to medium speed industrial bearings operating under adverse conditions.
