Thickness Selection Audit: 4mm vs. 5mm Sourcing Takeaways Click Seam & Tensile Strength: A 5.0mm core provides 25% deeper vertical locking engagement than a 4.0mm plank, offering significantly higher joint tensile resistance (ISO 24334) against seasonal movement and heavy rolling furniture. Subfloor Irregularity Tolerance: 4.0mm SPC requires an ultra-flat, fully leveled subfloor (variance ≤ 2mm

Technical Engineering Takeaways: Rigid Core Waterproof Flooring Inorganic Rigid Core Architecture: Engineered by compounding natural calcium carbonate (limestone) and virgin PVC resin under extreme heat, creating a 100% waterproof, non-hygroscopic core that eliminates swelling, cupping, or rotting under standing water. Multi-Layer Performance Engineering: Combines a double-crosslinked PUR UV protective coating, a heavy-duty transparent PVC wear

5mm SPC Wholesale Takeaways for Importers Define the Full Construction: Confirm whether “5mm” means a 5mm rigid plank without backing or a combined construction such as 4mm SPC plus 1mm IXPE. These products should not be treated as equivalent. Normalize Supplier Quotations: Compare core thickness, wear layer, backing, click system, surface, plank size, packaging, documents,

Underlayment Sourcing Takeaways: IXPE vs. EVA Acoustic Performance (IIC/STC): High-density IXPE (irradiation cross-linked polyethylene) features ultra-fine closed cells that provide superior impact sound insulation (IIC 70+), making it the mandatory standard for multi-family residential building codes. Long-Term Compression & Elasticity: EVA degrades, hardens, and suffers permanent compression set under sustained foot traffic, while IXPE maintains
