Structure & Material Composition

SPC flooring is a multi-layer composite system engineered for rigidity and waterproof performance:

• UV Coating: Scratch-resistant surface protection

• Wear Layer: Transparent PVC abrasion layer

• Decor Film: High-definition printed layer

• SPC Core: Limestone powder + PVC stabilizer composite

• Backing Layer: Stabilization film

• Optional IXPE/EVA Pad: Acoustic underlayment

The 60S Quick View: SPC Floor Manufacturing Process focuses primarily on the extrusion and lamination phases that create the rigid core structure.
