Explore our top-tier stainless steel polymer candle filter elements designed specifically for Ireland's demanding extrusion, medical tubing, and recycling applications.
Ireland has firmly established itself as one of the world's most dynamic hubs for high-precision manufacturing, bio-pharmaceutical engineering, and medical device extrusion. Regions like Galway, Cork, Dublin, Limerick, and Shannon host premier global MedTech corporations and high-performance polymer processors. These advanced production lines demand zero-defect polymer melts where contaminant particles, degraded gels, or microscopic carbonized spots can compromise structural integrity or optical clarity.
Simultaneously, under the European Union’s strict Circular Economy Action Plan and Ireland's Waste Action Plan for a Circular Economy, plastic processors throughout the country are rapidly converting towards high-percentage post-consumer recycled (rPET, rHDPE, rPP) resins and biodegradable polymers (such as PLA and PHA). The processing of recycled polymer melts introduces extreme viscosity fluctuations, elevated particulate loads, and abrasive contaminants that rapidly blind conventional single-layer mesh filters.
Information Gain Insight: Modern polymer continuous filtration vessels (CPF) in Ireland require multi-layer sintered metal fiber felt candle elements. Unlike standard wire mesh, sintered fiber felt provides an open porous structure of up to 85%, reducing differential pressure ($\Delta P$) by up to 40% while extending total on-stream filter element lifetime by 3x.
Our polymer candle filter elements are engineered to withstand continuous operating differential pressures of up to 250 bar (25 MPa) and temperatures surpassing 350°C without core collapse or pore migration.
Every candle element supplied to Irish clients undergoes 100% Bubble Point testing (ISO 4003) and dimensional validation, accompanied by complete EN 10204 3.1 material certificates for medical compliance.

| Multi-Layer Sintered Wire Mesh | 35% - 50% | Moderate | Medium | Standard Extruder Screen Pack Replacement, Recycled Granulation |
| Pleated Sintered Metal Mesh | 40% - 60% | High (Surface Area x4) | Low - Medium | High-Flow CPF Vessels, PET Resin Production, Viscous Monomer Lines |
| Square Plain Weave Mesh | 30% - 40% | Low | High | Coarse Pre-filtration, Heavy Scrap Plastic Recycling Lines |
Optimized polymer melt filtration solutions engineered to solve specific operational challenges across key Irish industrial sectors.
Medical tubing manufacturing (fluoropolymers, TPU, PEBAX) demands immaculate melt quality free from micro-gels or metallic fragments. Our high-precision 316L sintered fiber candle filter elements deliver absolute ratings down to 3 microns, preventing catastrophic wall-thinning or lumen occlusions during high-speed extrusion.
Biaxially Oriented Polypropylene (BOPP) and BOPET barrier films produced in Leinster industrial zones require continuous filtration without pressure spikes. Our multi-candle CPF elements utilize custom pleated geometries that maximize surface area, minimizing polymer shear stress and preventing web breaks during transverse orientation stretching.
Processing post-consumer recycled PET flakes into high-purity food-grade pellets involves high levels of non-melting contaminants (paper residues, aluminum, cross-linked polymers). Our heavy-duty SUS 316L polymer melt filter candles feature robust perforated inner support cores that endure rapid pressure changes during screen changover cycles.
For PP spunbond and meltblown nonwoven production, spinneret orifice clogging results in costly downtime. Our custom candle cartridges ensure uniform melt distribution, catching sub-micron carbonized gels before they reach the spin pack, dramatically enhancing nonwoven fiber tensile strength.
In continuous polymer filtration (CPF) housings, a critical engineering flaw often found in generic candle filters is the presence of stagnation zones near the top end-cap and bottom adapter. When high-viscosity polymers (such as Nylon 6,6, PET, or PBT) sit motionless in dead zones under elevated temperatures (280°C–320°C), thermal degradation occurs. This leads to carbonization, cross-linking, and periodic shedding of black specks into the clean polymer stream.

Candle filters offer significantly larger filtration area within a compact cylindrical footprint compared to leaf disc filters. This geometry provides streamlined vertical flow paths with reduced residence time distribution (RTD), making candle elements ideal for high-viscosity resins prone to thermal degradation.
For medical-grade TPU, PEBAX, and micro-tubing extrusion, we recommend absolute micron ratings between 3µm and 10µm using sintered stainless steel fiber felt. This guarantees the capture of micro-gels without generating excess shear heat.
