The purpose of the filter disc is to filter out the mechanical impurities, gel, coke and other contaminants in the melt and balance the pressure difference. Filter discs play a key role in the stable operation of film production lines and the production of high-quality products. Its structure is composed of two layers of stainless steel fiber sintered felt, two layers of perforated plates and a supporting distribution net (woven mesh or TP plate), which is a double-sided symmetrical composite structure.

The TP type filter disc is composed of perforated plate, TP plate and stainless steel fiber sintered felt. The middle is composed of stainless steel TP plate instead of stainless steel woven mesh, which reduces the pressure difference, and the Star gasket is separated from the disc. It is Mainly used for high viscosity special film. 

Material: stainless steel 304 or 316L. Size and precision can be made according to customer requirements.
