WhyUse Inorganic Thickeners in High-Temperature Grease? Key Benefits andApplications

    Inorganic thickenershave become the go-to choice for formulating high-temperature greases due totheir exceptional thermal stability and reliable performance in extremeenvironments.

In high-temperatureapplications, conventional soap-based greases often degrade or oxidize, makingthem unsuitable for prolonged exposure to heat. Inorganic thickeners fill thisgap by offering much better heat resistance.

As a vital part ofgrease formulation, thickeners typically make up 5% to 30% of the grease byweight. They convert base oil into a semi-solid form, enabling it to functionas a lubricating grease.

Common inorganicthickeners such as bentonite, silica gel, boron carbide, and carbon blackexhibit strong heat tolerance and high mechanical stability. They do not meltbut only evaporate slightly, making them perfect for centralized lubricationsystems and high-temp bearings.

These thickeners alsoenhance low-temperature performance, expanding the grease's operating range andensuring smooth startup and operation under varying climate conditions.

Becauseinorganic-thickened greases deliver consistent lubrication even under extremeloads and heat, they help extend bearing service life and reduce maintenanceneeds. As a result, they’re widely used in demanding industrial applications.
