SPC Flooring Density Comparison
SPC Flooring Density Comparison: Product Definition
SPC flooring density comparison refers to the evaluation of mass per unit volume within Stone Plastic Composite flooring cores. Density directly affects dimensional stability, load resistance, impact performance, and long-term durability, making it a critical engineering parameter for commercial and large-scale flooring projects.
Technical Parameters and Specifications
| Parameter | Typical Range | Engineering Impact |
|---|---|---|
| Core Density | 1,900–2,100 kg/m³ | Determines rigidity and stability |
| Calcium Carbonate Content | 60%–75% | Affects compressive strength |
| PVC Resin Content | 25%–40% | Influences flexibility and bonding |
| Flexural Strength | ≥35 MPa | Resistance to bending stress |
| Dimensional Stability | ≤0.15% | Expansion and contraction control |
| Impact Resistance | ≥12 kJ/m² | Prevents cracking under load |
Structure and Material Composition
UV Surface Coating: Protects against abrasion and staining

Decor Film: Printed wood or stone visual layer
SPC Core Layer: High-density composite of limestone and PVC
Underlayment (Optional): IXPE or EVA for acoustic control
Manufacturing Process
Raw Material Formulation: Precise limestone-to-PVC ratio defines target density
High-Speed Mixing: Ensures uniform particle dispersion
Extrusion: Core material formed under controlled temperature and pressure
Density Calibration: Inline measurement and thickness correction
Lamination: Decorative and wear layers bonded to SPC core
Quality Inspection: Density, flexural strength, and stability testing
Industry Comparison
| Flooring Type | Core Density | Structural Stability | Impact Resistance | Typical Application |
|---|---|---|---|---|
| SPC Flooring | 1,900–2,100 kg/m³ | Very High | High | Commercial & high-traffic |
| WPC Flooring | 1,100–1,300 kg/m³ | Medium | Medium | Residential use |
| LVT Flooring | 1,600–1,800 kg/m³ | Medium | Medium | Glue-down systems |
| Laminate Flooring | 850–950 kg/m³ | Low–Medium | Low | Dry indoor areas |
Application Scenarios
Distributors comparing SPC grades by density class
EPC contractors specifying flooring for heavy loads

Core Pain Points and Engineering Solutions
Cracking Under Load: Select SPC density ≥2,000 kg/m³
Thermal Expansion: Higher density improves dimensional control
False Density Claims: Require third-party test reports
Overweight Panels: Balance density with installation efficiency
Risk Warnings and Mitigation Strategies
Low-density SPC may deform under point loads
Excessive filler reduces bonding strength
Density inconsistency leads to joint failure
Ignoring density affects long-term performance guarantees
Procurement and Selection Guide
Define traffic load and subfloor condition
Set minimum SPC density requirement
Verify formulation and limestone ratio
Review mechanical test data
Request density consistency samples
Conduct pilot installation testing
Engineering Application Case
In a 12,000 m² commercial office project, SPC flooring with a core density of approximately 2,050 kg/m³ was selected. After two years of heavy foot traffic and rolling loads, no joint separation or core deformation was observed, reducing maintenance costs by an estimated 18%.
FAQ
What is SPC flooring density? It is the mass per unit volume of the SPC core.
Why is density important? It affects stability, load resistance, and durability.
Ideal SPC density for commercial use? Typically above 2,000 kg/m³.
Does higher density mean better quality? Only when formulation is balanced.
How is density measured? By mass-to-volume calculation in lab testing.
Can density affect installation? Yes, heavier panels need proper handling.
Is density related to wear layer? No, they are independent parameters.
Does density impact waterproofing? Indirectly, through structural integrity.
Can low density cause joint failure? Yes, under heavy loads.
How to verify supplier density claims? Request certified test reports.
