Chemical Foaming Technology — Conical Twin-Screw Controlled Cell Structure for Lightweight, Warm-Touch Flooring

The defining characteristic of WPC flooring — and the feature that differentiates it from SPC — is the foamed core. Jwell integrates chemical foaming directly into the conical twin-screw extrusion process:

– Foaming Agent Metering: A dedicated gravimetric dosing station introduces precisely measured foaming agent (typically azodicarbonamide, sodium bicarbonate-based, or endothermic/exothermic blends) into the PVC/wood-flour/calcium-carbonate compound. The dosing accuracy of ±0.5% ensures consistent foam density from the first plank to the last.

– Controlled Decomposition Zone: The extruder’s temperature profile is engineered so the foaming agent decomposes at the precise point in the metering zone where the PVC resin is fully plasticized and the wood flour is uniformly dispersed. Decomposition temperature (typically 160-190°C for azodicarbonamide) is controlled within ±2°C by individual barrel zone PID controllers.

– Cell Structure Control: The gas released by the foaming agent creates a microcellular structure throughout the core cross-section. Jwell’s screw geometry manages the melt pressure downstream of the decomposition zone — sufficient back-pressure prevents premature bubble coalescence (which creates large, irregular cells with poor mechanical properties), while controlled pressure drop at the die lip allows uniform expansion to the target density.

– Density Range: WPC core density is typically 700-900 kg/m³ (foamed) compared to SPC’s 1,000-1,500 kg/m³ (solid). This 30-50% weight reduction is what gives WPC its lighter handling weight, softer feel, and superior acoustic properties.

Wood Flour Compounding — Natural Fiber Integration for Authentic Wood-Like Properties

WPC’s “wood” character comes from the incorporation of wood flour (typically 30-50 mesh hardwood powder) into the PVC matrix. The wood flour contributes the warm tactile feel, reduces the plastic content (lowering raw material cost and improving environmental profile through renewable content), and provides the density reduction that complements the foaming process.

Jwell’s WPC line integrates a dedicated wood flour handling system:

– Pre-Drying: Wood flour contains 5-8% moisture as received, which must be reduced to below 0.5% before extrusion to prevent steam voids and surface defects. A desiccant or hot-air dryer with 2-3 hour residence time at 90-100°C conditions the wood flour before it enters the dosing system.

– Dedicated Dosing Station: A separate gravimetric feeder for wood flour operates alongside the PVC resin, CaCO₃, stabilizer, and foaming agent feeders, with all components blended in the high-speed mixer before introduction to the extruder. This multi-component blending approach ensures uniform wood flour dispersion throughout the extruded sheet — non-uniform dispersion creates visible density streaks and inconsistent local mechanical properties.

– Vented Barrel Moisture Removal: Despite pre-drying, residual moisture from the wood flour is removed through the extruder’s vacuum vent zone — a water-ring pump maintains negative pressure at the vent port, extracting steam and volatiles before they reach the die.

Embossing Calender — Realistic Wood-Grain Surface Texture Applied During Extrusion

WPC flooring’s market appeal depends on its ability to replicate the look and feel of natural hardwood. Jwell’s embossing calender applies realistic wood-grain texture to the hot extruded sheet in a single in-line pass — the texture is pressed into the surface while it is still above the glass transition temperature, creating a permanent emboss that will not wear off like a printed or coated surface pattern:

– Embossing Roll Technology: The calender roll features a precision-engraved wood-grain pattern produced by chemical etching or laser engraving, with texture depth of 0.1-0.3 mm and pattern repeat length matched to common plank formats. Interchangeable rolls allow changeover between oak, walnut, maple, hickory, and exotic wood grain patterns in under 30 minutes.

– Temperature-Controlled Embossing: The roll surface temperature is maintained at 60-90°C (±1°C uniformity) — hot enough that the WPC surface flows into the texture cavities under calender nip pressure, but not so hot that the material sticks to the roll surface. A release agent spray system applies a micro-thin coating of release agent to the roll surface to prevent sticking.

– Registered Emboss Capability: For premium WPC products, the embossing roll can be synchronized with the decorative film laminator to register the embossed wood grain with the printed wood-grain pattern — creating an “embossed-in-register” (EIR) surface where the texture valleys align with the printed grain lines, delivering the most authentic wood-look flooring available in the WPC category.

UV Cured Top Coat — Transparent Scratch & Stain Protection for WPC Flooring

The UV coating workcell applies a transparent, scratch-resistant top coat over the embossed and decorated WPC surface, protecting the decorative layer from wear, stains, and UV yellowing:

– Two-Stage Application: Primer coat (adhesion layer) → UV cure → top coat (hardness layer) → UV cure. The primer penetrates the micro-porous embossed surface for mechanical anchoring; the top coat builds the hard, crosslinked surface that resists scratching from foot traffic, pet claws, and furniture movement.

– Wear Performance: Properly formulated and cured UV coatings on WPC achieve AC3-AC4 wear ratings (Taber abrasion), sufficient for residential and light-commercial applications. The coating thickness is 15-25 μm after cure — thick enough for scratch protection, thin enough to not fill in the embossed wood-grain texture that gives the flooring its realistic feel.

– UV Cure System: Medium-pressure mercury UV lamps (or LED UV for heat-sensitive substrates) deliver the UV energy density required for complete crosslinking. The intelligent power controller adjusts lamp output to line speed, reducing electricity consumption by 25-30% compared to fixed-output systems.

Comfort-First Residential WPC Flooring — Warmer, Softer Feel for Bedrooms, Living Rooms & Family Spaces

WPC flooring’s warm touch, soft feel, and natural wood-grain appearance make it the preferred flooring for residential spaces where comfort is the primary decision criterion. The foamed core provides insulation from cold concrete subfloors — a meaningful comfort difference in basements, ground-floor rooms, and homes in colder climates. The 7″ × 48″ plank format in oak, walnut, or hickory wood-grain embossed patterns covers the most popular residential design aesthetics, while the click-lock installation enables DIY-friendly weekend renovation projects.

Hospitality WPC Flooring — Superior Sound Insulation Between Guest Rooms

Hotel operators specify WPC flooring for guest rooms primarily for its acoustic performance: the foamed core absorbs impact noise from footsteps, dropped objects, and furniture movement, reducing sound transmission to the room below by 18-22 dB. This acoustic damping is a competitive requirement in multi-story hotels where guest complaints about noise from above are the number one cause of negative reviews and room-change requests. WPC’s realistic wood-grain appearance supports the premium design language of 4-star and 5-star properties, while its durability withstands the rolling loads of luggage carts and housekeeping equipment in corridor applications.

Frequently Asked Questions

What is WPC flooring and how is it different from SPC? -

WPC (Wood Plastic Composite) flooring has a foamed core — PVC resin blended with wood flour, calcium carbonate, and foaming agents creating a microcellular structure at 700-900 kg/m³ density. The foamed core gives WPC a warmer, softer feel closer to natural wood, along with superior sound insulation (18-22 dB impact reduction). SPC has a solid mineral core at 1,000-1,500 kg/m³ density — harder, colder, but 100% waterproof and more dimensionally stable. Choose WPC for comfort and acoustics; choose SPC for durability and waterproofing.

What foaming technology does the Jwell WPC line use? +

The Jwell WPC line uses chemical foaming agents metered into the compound before extrusion. The conical twin-screw extruder controls foam cell structure through precise temperature profiling — the foaming agent decomposes at a controlled point in the metering zone, releasing gas that forms the microcellular core. The T-die and embossing calender set the foam structure and surface texture simultaneously. This in-line process produces consistent foam density without post-extrusion foaming steps.

What WPC flooring thicknesses and plank formats can this line produce? +

The line produces WPC flooring in 4-8 mm thickness and up to 1,350 mm sheet width. Standard plank formats include 6″×36″, 7″×48″, and 9″×48″, with tile formats (12″×24″, 18″×18″) through secondary cutting. The thicker foam core (6-8 mm) provides the acoustic damping that distinguishes premium WPC from thinner SPC planks.

Does Jwell offer both WPC and SPC lines, and can I produce both on one machine? +

Yes — Jwell supplies both WPC foamed-core and SPC solid-core flooring production lines. A single WPC line can also produce non-foamed rigid PVC flooring by switching off the foaming agent dosing and adjusting the temperature profile. However, for producers targeting both WPC and SPC markets at commercial scale, dedicated lines are recommended because the optimized screw geometry and downstream equipment sizing differ between the two processes.
