Wide temperature adaptability enables organic bentonite-based grease to operate reliably in extreme temperature environments, breaking through the temperature limitations of traditional products.
In low-temperature performance testing, the starting torque at -30°C is 25% lower than that of traditional lithium-based grease, meeting the starting requirements of construction machinery in cold regions; In high-temperature stability tests, the evaporation loss rate at 180°C is only 5%, significantly lower than the 15% level of traditional products, making it suitable for high-temperature components such as engine and kiln bearings.
This wide temperature range is attributed to the dual role of organic bentonite: at low temperatures, the flexibility of the organic chains ensures the grease does not harden, while at high temperatures, intermolecular forces maintain the stability of the gel structure.
After adopting this lubricant, a cold-region oilfield achieved a winter equipment startup success rate of 100% (up from 70%), while also withstanding summer temperatures exceeding 40°C, enabling year-round use without lubricant replacement.
Organoclay for Grease
Organophilic clay CP-720A is a kind of purified and modified organoclay rheological additive, designed especially for using in Grease based on synthetic oils such as vegetable oil, polyester oil. Organic clay has high gelling efficiency, fine thixotropy and perfect anti-settling.
Organiclay bentonite CP-720A is used in the following applications:
Advantages of Organoclay Rheological Additive
Properties of Organoclay
Composition Organic derivative of a montmorillonite clay
Appearance Fine powder, light yellow
Moisture content (105℃,2hr) ≤3.5%
Loss on ignition (1000℃) 34%-36%
Bulk density 0.42g/cm3
Fineness (<74μm, %) ≥98%
Organobentonite Packages
Kraft paper bag with PE liner or multi-wall paper sacks or customized. 25kg/bag or 22.68kg/bag or customized.
Organophilic clay Store in a dry, well-ventilated area with temperature of 0℃-30℃. Keep container closed. The quality guarantee period is 24 months.
When it is used in Grease Lubricant, polar activator is needed. Polar activator is acetone/water(95/5). The dosage of activator is 20%-30% of the weight of CP-720A. And also high shear can promote the dispersing of rheology modifier CP-720A.
Adding procedure as follows:
Note: With High-speed dispersant of grinding machine, and properly prolong the dispersing time, better gelatin performance can be reached.
The Lubricanting grease which uses organoclay as thickener will own high dropping point, thus can be used under high temperature and presents good impermeability and water resistance.
