The technical specifications of waterproof laminate flooring are important standards for measuring its performance and quality, typically including the following aspects:
1. Waterproof Performance：
Thickness Swelling Rate: Reflects the degree of expansion after water absorption, usually required to be ≤18% (24-hour immersion).
Surface Water Resistance: The floor surface should show no significant changes, such as bubbling, cracking, or fading, after contact with water.
2. Wear Resistance：
Abrasion Resistance (Revolutions): Household-grade flooring typically requires ≥6,000 revolutions, while commercial-grade requires higher standards (≥9,000 revolutions).
Thickness of Wear Layer: Usually 0.1-0.7mm; the thicker the layer, the better the wear resistance.
3. Dimensional Stability：
Dimensional Change Rate: Reflects the stability of the flooring under changes in temperature and humidity, usually required to be ≤0.5%.
4. Impact Resistance：
Impact Strength: The floor's ability to resist damage under heavy impact, typically tested through a ball-drop test.
5. Environmental Performance：
Formaldehyde Emission: Should comply with international environmental standards, such as E1 grade (≤0.124mg/m³) or stricter E0 grade (≤0.05mg/m³).
VOC (Volatile Organic Compounds) Content: Should be lower than relevant environmental standards.
6. Compressive Strength：
Static Bending Strength: Reflects the floor's resistance to bending, usually required to be ≥30MPa.
Elastic Modulus: Reflects the floor's rigidity, usually required to be ≥2500MPa.
7. Stain Resistance：
Surface Stain Resistance: The floor surface should resist common stains (e.g., ink, coffee) and be easy to clean.
8. Heat Resistance：
Heat Resistance: The floor should show no significant deformation or damage under high temperatures, typically tested through high-temperature baking tests.
9. Slip Resistance：
Friction Coefficient: The floor surface should have a certain level of slip resistance, usually requiring a static friction coefficient of ≥0.5.
10. Locking Strength：
Locking Pull Force: Reflects the strength of the floor's locking connection, usually required to be ≥1000N.
11. Light Resistance：
Lightfastness: The floor should show no significant fading under prolonged light exposure, typically tested through UV exposure tests.
12. Thermal Conductivity：
Thermal Conductivity: Flooring suitable for underfloor heating systems should have good thermal conductivity, usually requiring a thermal conductivity coefficient of ≥0.15W/(m·K).
13. Fire Resistance：
Fire Rating: Should comply with national or international fire safety standards, such as B1 grade (flame-retardant material).
14. Antibacterial Performance：
Antibacterial Rate: Some high-end waterproof laminate flooring features antibacterial properties, usually requiring an antibacterial rate of ≥99%.
15. Ease of Installation：
Installation Method: Typically uses a click-lock system, requiring simple installation and tight seams.
These technical specifications collectively ensure the excellent performance of waterproof laminate flooring in terms of waterproofing, durability, environmental friendliness, safety, and more, meeting consumers' demands for high-quality flooring.
Waterproof vs Regular Flooring
| Parameter | Waterproof Flooring | Regular Flooring |
| Water Resistance | Highly resistant to water and moisture | Not resistant to water; can warp or swell |
| Durability | Highly durable, resistant to scratches and stains | Less durable, prone to scratches and damage |
| Maintenance | Easy to clean, requires minimal maintenance | Requires regular maintenance and care |
| Installation | Can be installed in wet areas (e.g., bathrooms, kitchens) | Not suitable for wet areas |
| Lifespan | Long-lasting, especially in high-moisture areas | Shorter lifespan in high-moisture conditions |
| Aesthetic Options | Wide range of designs, including wood and stone looks | Limited by natural material characteristics |
| Environmental Impact | Some types may contain synthetic materials | Natural materials like wood are eco-friendly |
| Comfort | Can feel harder underfoot | Softer feel, especially with carpet or cork |
