Application guide for Polymer Leaf Disc Filter to Custom to filter housing. The core duty of the type is filtering polymer melt for film, fiber and engineering resins in stacked leaf disc filters that pack large filter area into a compact housing. The typical industries, the how-to-specify checklist, handling practice and the exclusion cases are set out below.
Typical Applications for Polymer Leaf Disc Filter
Where Polymer Leaf Disc Filter is specified and bought:
- BOPET & BOPP film: melt filtration for optical and packaging film.
- Polyester & nylon fiber: continuous polymerization melt filters.
- Engineering plastics: PC and PET bottle-grade resin.
- Recycled PET: high-purity rPET melt.
How to Specify Polymer Leaf Disc Filter for Your Application
- Disc size: 7, 10 or 12 in diameter with the housing hub size.
- Micron rating: 3–40 µm; finer for optical film.
- Media: Sintered fiber felt for depth; dutch weave for surface filtration.
- Standard: Quote Custom to filter housing and the size designation from the table on the product page, plus any value you changed in the technical drawing.
Handling & Installation Practice
- Clean in a vacuum pyrolysis oven, then ultrasonically, then bubble-point test each disc.
- Replace hub seals at every rebuild.
Common Selection Mistakes with Polymer Leaf Disc Filter
- Skipping integrity tests after cleaning.
- Mixing disc ratings in one stack.
Where Polymer Leaf Disc Filter Is Not the Right Choice
Not for low-viscosity liquids where cartridges are simpler.
