Plastic pall rings usually have a light specific gravity, which brings many performance advantages. The lighter specific gravity makes the plastic pall ring more convenient during transportation and installation, reducing logistics costs. At the same time, it also makes the filling density of plastic pall rings in the equipment higher and improves filtration efficiency.

In addition to the specific gravity advantage, plastic pall rings also have good corrosion resistance, wear resistance and mechanical strength. These properties allow it to operate stably in a variety of harsh environments and extend its service life. In addition, plastic pall rings also have good water absorption, adsorption and thermal stability, and can maintain stable filtration performance under different temperature and humidity conditions.
