Polymer Melt Candle Filter is used for filtering polymer melt in continuous polymerization and large extrusion lines with long pleated candles of stainless fiber felt or sintered mesh, hung in a multi-candle housing. Custom to filter housing is the reference cited for it on drawings, datasheets and purchase orders.
What Custom to filter housing Means for Polymer Melt Candle Filter
The dimensions in the table below are supplied to suit Custom to filter housing. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.

Specifying Polymer Melt Candle Filter Beyond the Standard
- Size & connection: Diameter, length and the thread, flat seat or flange the housing uses.
- Micron rating: 5–60 µm; finer ratings raise pressure and residence time.
- Media & pleat: Fiber felt for dirt capacity, sintered mesh for strength.
When Polymer Melt Candle Filter Is Not the Right Choice
Not for small extruders, where screen packs or a screen changer are simpler and cheaper.
