Direct Factory 5mm Waterproof SPC Vinyl Flooring

The product consists of a stone‑plastic composite core topped with a transparent wear layer and a printed decorative film. Overall thickness is 5 mm, with a wear layer typically 0.3 mm thick. The core formulation blends calcium carbonate (≈60 % by weight), PVC resin, and stabilizers to achieve a density of about 1.9 g/cm³.

Technical Specifications

Core Layer Composition and Structure

The SPC core is manufactured by high‑speed extrusion of a dry blend of limestone powder, PVC, and plasticizers. The extruded sheet is cooled, calibrated to 5 mm thickness, and then laminated with a printed film and a wear layer using a hot‑press cycle. The click‑locking profile is milled into the edges after lamination, allowing floating installation without adhesives.

Because the core contains no wood fibers, it exhibits negligible swelling when exposed to moisture, making it suitable for wet environments such as food‑processing washdown areas or locker rooms.

Manufacturing Process Overview

Raw materials are weighed and mixed in a twin‑screw extruder under controlled temperature (≈180 °C) to ensure uniform dispersion of the calcium carbonate. The melt is forced through a die to form a continuous sheet, which is then pulled through a series of cooling rollers to achieve dimensional stability.

After cooling, the sheet passes through a laminating station where the decorative film and wear layer are bonded under heat and pressure (≈150 °C, 2 MPa). The laminated sheet is then cut to length, and the locking profile is milled on a CNC router. Final inspection includes thickness gauging, surface defect scanning, and locking‑fit testing.

Performance Characteristics in Industrial Settings

The low water absorption (<0.05 %) prevents delamination when the flooring is subjected to frequent wet cleaning or occasional spills. The dimensional stability under heat (≤0.15 % change) ensures that joints remain tight in areas with temperature fluctuations, such as near ovens or refrigeration units.

A wear layer of 0.3 mm provides a abrasion resistance rating suitable for medium‑traffic zones (e.g., corridors, assembly lines) while still allowing recoating if surface renewal is required after several years of service.

Slip resistance rated R10 meets the requirements for areas where water or oil may be present, reducing the likelihood of slip incidents in workshops and maintenance bays.

Applications: Why This Flooring Fits Specific Industries

In automotive parts manufacturing, the flooring resists oil and coolant exposure, and its click‑lock system allows rapid replacement of damaged sections without shutting down the entire line.

For pharmaceutical cleanrooms, the non‑porous surface does not harbor particulates, and the low VOC emission supports compliance with indoor air quality standards.

In retail environments such as showrooms, the product offers a stable substrate for heavy display fixtures while providing a quiet underfoot feel due to the dense core.

Quality Control and Testing Philosophy

Each production lot undergoes inline thickness monitoring with laser gauges, targeting a tolerance of ±0.1 mm. Surface inspection stations use high‑resolution cameras to detect scratches, color variation, or embossing defects above a defined threshold.

Mechanical properties are verified on samples cut from the line: wear layer adhesion is measured by a peel test (≥1.5 N/mm), and impact resistance is evaluated using a falling‑weight apparatus (≤10 mm indentation at 1 J). Results are logged and compared to internal control charts before release.

Customization Options

Thickness can be adjusted between 4 mm and 6 mm by altering the core extrusion rate while keeping the wear layer at 0.3 mm for projects requiring higher load bearing.

Wear layer thickness is offered in 0.2 mm, 0.3 mm, and 0.5 mm variants, allowing customers to match the expected abrasion level of their facility.

Locking profiles are available in standard 5‑mm click, a double‑lock variant for shear‑prone areas, and a glue‑down option for permanent installations.

Surface finishes include matte, low‑gloss, and embossed textures that mimic wood, stone, or concrete patterns; custom embossing logs can be supplied upon request.

Packaging and Logistics

Boards are packed in cartons of 2 m², with each carton weighing approximately 18 kg. Cartons are stacked on pallets (max 1.2 m high) and secured with stretch film and corner boards to prevent shifting during transit.

For export shipments, moisture‑barrier liners are inserted inside the cartons, and pallets are treated according to ISPM‑15 standards. Tracking labels include batch numbers, production date, and destination details to facilitate traceability.

Frequently Asked Questions

• Can dimensions be customized? Yes, board length and width can be cut to project‑specific sizes; standard plank width is 180 mm, length 1.2 m, but custom lengths up to 2.4 m are available.
• What information is required before quotation? Required details include total area, desired thickness, wear layer grade, locking type, surface finish, and any special packaging or certification needs.
• How is quality inspected? Inline thickness gauging, surface camera inspection, and mechanical testing (peel, impact, dimensional change) are performed on each batch; test reports are available upon request.
• What packaging methods are available? Standard carton packing, palletizing with stretch film, and optional moisture‑barrier liners for overseas transport.
• What is the typical production lead time? Lead time varies with order size and customization; typical range is 2‑4 weeks after receipt of confirmed technical specifications and deposit.
