Wholesale Rigid Core SPC Vinyl Flooring Manufacturer

Stone Plastic Composite (SPC) rigid core flooring combines a limestone‑filled core with a printed vinyl wear layer and a UV‑cured top coating. The result is a product that exhibits high dimensional stability, resistance to moisture, and impact tolerance suitable for heavy‑traffic commercial environments.

Material Composition and Structure

The core consists of approximately 60% calcium carbonate, 30% polyvinyl chloride, and 10% additives that enhance rigidity and flame retardancy. A printed decorative film is laminated onto the core, followed by a wear layer typically ranging from 0.3 mm to 0.7 mm in thickness. A UV‑cured polyurethane top coat provides scratch resistance and facilitates cleaning.

Dimensional Specifications

Performance Characteristics

The limestone‑filled core yields a density of approximately 1.9–2.1 g/cm³, contributing to indentation resistance measured at ≤0.05 mm after a 500 kg static load. The wear layer achieves a Taber abrasion index of ≤300 mg loss per 1000 cycles, corresponding to AC4 classification. Water absorption after 24 h immersion remains below 0.02%, ensuring dimensional stability in wet areas.

Manufacturing Process

Raw materials are blended in a twin‑screw extruder at temperatures between 160 °C and 180 °C, producing a homogeneous melt that is calendared into sheets of specified thickness. The sheets undergo embossing to replicate wood or stone textures, then are laminated with the printed film and wear layer under high pressure. Final cooling, cutting to length, and application of the UV top coat occur in-line before quality inspection.

Applications and Suitability

Due to its rigidity, SPC flooring tolerates uneven subfloors better than traditional LVT, reducing the need for extensive floor preparation. The product’s fire rating (typically Bfl‑s1) and low VOC emissions make it appropriate for healthcare facilities, educational institutions, and retail spaces where indoor air quality is regulated.

• High‑traffic corridors and lobbies
• Wet areas such as locker rooms and kitchenettes
• Industrial showrooms with occasional equipment loads
• Multi‑family residential units requiring acoustic performance

Quality Control and Testing

Each production lot is sampled for thickness variation (±0.1 mm), wear layer adhesion ( peel strength ≥1.5 N/mm), and dimensional change after heat aging (≤0.2% after 8 h at 70 °C). Finished boards undergo a slip resistance test (R10 per DIN 51130) and a chemical resistance assessment against common cleaning agents. Results are recorded and available to buyers upon request.

Customization Options

Beyond standard wood and stone prints, manufacturers can apply custom logos, corporate colors, or specific pattern repeats via digital printing. Core thickness, wear layer thickness, and emboss depth can be adjusted to meet project‑specific load or acoustic requirements. Edge profiling (square, beveled, or micro‑bevel) is also selectable.

Packaging and Logistics

Planks are stacked in cartons that typically contain 2.0 m² to 2.5 m² of flooring, depending on plank dimensions. Cartons are placed on pallets with stretch film and corner protectors to prevent movement during transit. For export shipments, moisture‑barrier liners and ISPM‑15 compliant pallets are used to meet international regulations.

Frequently Asked Questions

Can dimensions be customized?

Yes. Plank width, length, overall thickness, and wear layer thickness can be adjusted according to project specifications, subject to tooling availability.

What information is required before quotation?

Required details include desired dimensions, wear layer thickness, surface finish, order quantity, delivery destination, and any specific certification needs (e.g., FloorScore, CE).

How is quality inspected?

Incoming raw materials are tested for calcium carbonate purity and PVC melt flow index. In‑process checks monitor thickness and emboss depth. Final inspection includes dimensional checks, wear layer adhesion, slip resistance, and visual defect grading.

What packaging methods are available?

Standard packaging uses cardboard cartons on pallets with stretch film. Optional options include shrink‑wrapped cartons, plastic corner guards, and customized labeling for retail distribution.

How are export shipments protected?

Export pallets are fitted with moisture‑barrier liners, edge protectors, and are secured with polyester strapping. ISPM‑15 heat‑treated pallets are used to comply with phytosanitary regulations.
