Windmill bearing lubricants are a specialty lubricant application that requires high viscosity where normal mineral oils with viscosity boosting additives may not perform as well as naturally higher viscosity mineral oil. The superior stability of the high viscosity white oil and its long molecules reduce migration to the surface of rubber-like plastic parts that can be used for food contact. High viscosity white oils can also be used to create food-grade items. Another excellent application for high viscosity oil is as a grease component that can handle heat. Using high viscosity oils mean that the soft-touch parts remain soft because the oil remains in the parts even through years of high-temperature use (think hot summer interiors of cars). Lighter oils evaporate in high-temperature applications like baking or as automotive soft-touch interior components. The advantage of high viscosity oils is that they have longer molecules and higher boiling point which means that they stay where they are put.
While many people think of oils as a cooking ingredient or as motor oils, high viscosity oils are used in more specialized applications. High viscosity oils refer to higher molecular weight (longer molecules), lower volatility oils that are thicker than others. The chemical makeup of a liquid determines its viscosity, as well as defining potential applications. High viscosity liquids are thicker, such as syrup, while low viscosity liquids are thinner, like water. This quality impacts how the liquid moves and flows, as well as what it can be used for.
Generally speaking, viscosity refers to the thickness of a liquid. This basic guide to high viscosity oils will help you understand where they’re used and what makes an oil count as high-viscosity. In fact, the United States is the world’s number one producer and consumer of mineral oil, representing an 18% share. Different types of mineral oils are everywhere in daily life, from baby oil, engine lubrication oils to high viscosity oils and many more.
