The packing has advantages such as light, high capacity, low pressure drop, large specific surface area, easy replacement, etc. It is widely used in unit operations like rectification, absorption and extraction.
The material's heat resistance reaches 100℃ for PP and 150℃ for PVDF. The packing sheet may be perforated with small holes to increase mass transfer efficiency. If the separation requirement is not high, it needs no perforation on the surface. In this way the sheet stiffness can be ensured.
