Core Definition and Composition

SPC flooring is an engineered luxury vinyl flooring constructed with a rigid core composed primarily of natural limestone powder (calcium carbonate), polyvinyl chloride (PVC) resin, and stabilizers. The material’s defining characteristic is its dense, waterproof core that delivers superior dimensional stability and impact resistance compared to traditional vinyl flooring options.​

The typical composition includes:

  • Limestone powder (calcium carbonate): 60-70% of core composition, providing strength and rigidity
  • PVC resin: 25-35%, binding limestone particles and creating waterproof properties
  • Stabilizers: Added to enhance dimensional stability and temperature resistance

Layer Structure

SPC flooring features a sophisticated multi-layer engineered structure, typically comprising 4-5 distinct layers:

1. ​Top UV Layer

Transparent UV-protected ceramic bead coating providing stain resistance, waterproofing, and fade protection

2. Wear Layer

Transparent protective topcoat (0.2mm-0.7mm thickness) that shields the decorative layer from scratches, scuffs, and abrasion

3. Decorative Layer

High-definition printed vinyl film featuring realistic wood, stone, marble, or abstract designs

4. Rigid SPC Core

High-density stone-polymer composite core (3.0mm-6.5mm) delivering structural integrity, waterproofing, and dimensional stability

5. Underlayment (Optional)

Integrated underlayment (IXPE, EVA, or cork) providing sound insulation, comfort, and moisture barrier properties

Key Performance Characteristics

– Waterproof Performance: The rigid SPC core is 100% waterproof, making it suitable for moisture-prone environments including kitchens, bathrooms, basements, and commercial spaces. Unlike wood-based flooring, SPC does not swell or warp when exposed to water.
​- Dimensional Stability: The stone-based composition provides exceptional resistance to expansion and contraction from temperature fluctuations and humidity changes. SPC maintains stability in temperatures ranging from -25°F to 155°F (-31.6°C to 68.3°C).
​- Impact and Indentation Resistance: The high-density rigid core resists dents and damage from heavy furniture, dropped objects, and high foot traffic. This makes SPC superior to softer WPC (Wood Plastic Composite) alternatives for commercial applications.
​- Scratch and Wear Resistance: Enhanced wear layers with UV coating and protective technologies (e.g., ArmorBead™, ScratchResist®) deliver superior scratch resistance suitable for households with pets and high-traffic commercial environments.

Product Thickness (core + wear layer): 4 – 7 (mm).

– Dimension (Customized):
+ 48×7.2 (inch) / 1220×183 (mm)
+ 48×9 (inch) / 1220×228 (mm)
+ 60×9 (inch) / 1524×228 (mm)
+ 36×6 (inch) / 915×153 (mm)
– PVC Film: Oak/Walnut/Hickory.
– Underlayment: IXPE (1-2mm); EVA (1-2mm).
– SPC Flooring Click: Unilic patented technology, I4F.
– Color: More than 200 colors and styles.
– Lead Time: 15-35 days.
– Guarantee: 7 years commercial, 20 years residential.
– Certificated: SGS, FloorScore, Greenguard Gold, CE, ISO 9001:2015.

Physical and Mechanical Properties

– Density: SPC core density ranges from 1.8 to 2.1 kg/m³, significantly higher than WPC alternatives (1.4-1.6 kg/m³). Higher density correlates with better impact resistance and durability.
​- Load-Bearing Capacity: High-quality SPC flooring withstands static loads exceeding 500 lbs per square inch without permanent indentation when properly installed.
​- Abrasion Resistance: Tested using the Taber abrasion test, premium SPC flooring with 0.5mm wear layers demonstrates resistance exceeding 4,000-6,000 rotations before visible wear.
​- Slip Resistance: R-rating typically ranges from R9 to R11, with higher values indicating superior slip resistance. Commercial applications often require R10 or higher.
​- Fire Resistance: SPC flooring typically achieves Class Bf1-s1 or Class A fire ratings per EN 13501-1 and ASTM E84 standards, indicating excellent fire resistance.
​- Thermal Conductivity: Compatible with underfloor heating systems with maximum surface temperature limits of 27-29°C.

Key Advantages:

– 100% waterproof
– UV resistant, color-stable
– Anti-slip surface
– Easy to clean and maintain
– Suitable for all rooms and traffic levels

As a pet owner, finding a floor that could withstand my golden retriever's energy was a challenge. I am beyond impressed with the durability of this flooring. After months of heavy foot traffic and occasional 'zoomies,' there isn't a single scratch or scuff mark in sight.
