Polymer Melt Candle Filter (Custom to filter housing) 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.
Media & pleat: Fiber felt for dirt capacity, sintered mesh for strength.
Materials
Standard supply is stainless steel 316/316L; the material column in the table and the drawing options show the exact grade for each size. Other alloys and finishes can be quoted to your drawing.
Fitting & Care
Clean by vacuum pyrolysis, hydrolysis or solvent, then ultrasonics and bubble-point testing.
Torque candle threads to the housing maker's values to avoid leaks at the seat.
Common Mistakes
Re-installing candles without an integrity test after cleaning.
Mixing candles of different ratings in one housing.
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.
Polymer Melt Candle Filter is made to order as finished parts. Indicative pricing starts from about US$120.00 per piece for a standard size at production quantity; the final price depends on size, material, finish, tooling and order volume.

What is a polymer candle filter?
A long pleated cylindrical element that filters polymer melt in a multi-candle housing.
How are candle filters cleaned?
By vacuum pyrolysis or chemical cleaning, then ultrasonic rinsing and bubble-point testing.
Fiber felt or sintered mesh candles?
Fiber felt holds more gels and dirt; sintered mesh is stronger.
