Leaf Disc Filters – Achieving Efficient Filtration of Polymer Melts

Leaf disc filters, also known as polymer melt filters, belong to a type of polymer filter. Leaf disc filters are suitable for high temperature, corrosive reaction environments to filter high temperature viscous polymers in the rubber and plastics industry. Its disc design increases the effective filtration area per unit area, which makes it possible for the effective use of space and miniaturization of the filtration device. Structurally, leaf disc filters are divided into central ring polymer extruder screens, and central ring wrap-around polymer melt filters.

According to the material, it is divided into stainless steel sintered felt and multi-layer stainless steel sintered mesh. Among them, stainless steel sintered felt has a large capacity to hold dirt, a long service life, and good air permeability. The advantage of stainless steel sintered mesh is high lightness, and impact resistance, but low dirt-holding capacity. Clients can choose the type of disc filter that fits the application scenario.
