1. Industrial Lubricants
PAG is commonly used as a base oil for gear oils and high-temperature chain oils. It offers a high viscosity index, good extreme pressure performance, and low carbon deposit tendency. Suitable for heavy-duty gear systems in equipment such as textile heat-setting machines and plastic calenders, it remains stable at high temperatures and demonstrates good compatibility with rubber seals.
2. Compressor and Refrigeration Oils
Polyalkylene Glycol exhibits good miscibility with refrigerants such as R-134a and possesses clean-burning characteristics, helping to reduce sludge and carbon deposits. With excellent lubricity, chemical stability, and low-temperature fluidity, it is widely used in automotive air conditioning and industrial refrigeration systems.
3. Metalworking Fluids
PAG can form an effective lubricating film on metal surfaces, providing outstanding lubrication and cooling effects. It exhibits reverse solubility—soluble in water at room temperature but precipitating and adhering to metal surfaces when in contact with high-temperature tools, thereby enhancing lubrication. It is often used in fully synthetic or semi-synthetic metalworking fluids.
Zhengzhou Chorus specializes in lubricant additives, with Polyalkylene Glycol (PAG) as one of our flagship products. For applications such as gear oils, compressor oils, and refrigeration oils, we provide customized solutions that deliver cleanliness, cooling, lubrication, and environmental performance.
