PP hollow ball fillers have a wide range of applications in many industrial fields, especially in some applications where efficient heat transfer and reduced drag are required. Its unique filling effect is mainly manifested in the following aspects:
Hollow ball packing can significantly improve the heat transfer efficiency of equipment. Since its interior is hollow, it can be filled with more hot media, such as hot water or steam, so that it forms a layer of heat inside the device. This not only speeds up heat transfer, but also reduces heat loss and improves the energy efficiency of the equipment. 
Secondly, hollow ball packing can reduce fluid resistance. When filling equipment, hollow ball packing can form a continuous, relatively stable ball bed, allowing the fluid to flow more smoothly through the equipment. This continuous pebble bed structure can effectively reduce the frictional resistance of the fluid and reduce the pressure loss of the fluid. In addition, the hollow ball packing also has good wear and corrosion resistance. This material is usually made of high-quality materials such as stainless steel or ceramic, which can operate stably in various harsh industrial environments and effectively extend the service life of equipment. 
In summary, hollow ball packing plays a role in efficient heat transfer, reducing fluid resistance, and improving equipment durability in equipment. These characteristics make hollow ball packing an ideal industrial filler, which is widely used in petroleum, chemical, electric power, environmental protection and other fields. With the continuous development of science and technology, the application prospect of hollow ball packing will be broader.
