3.5mm Waterproof Vinyl Flooring SPC Manufacture

Product Definition

3.5mm Waterproof Vinyl Flooring SPC is a rigid core flooring product manufactured using a stone-plastic composite formulation, designed to deliver dimensional stability, moisture resistance, and consistent mechanical performance for commercial and residential construction projects.

Technical Parameters and Specifications

The technical design of 3.5mm Waterproof Vinyl Flooring SPC focuses on balancing thickness control, wear resistance, and installation compatibility across global flooring standards.

Structure and Material Composition

3.5mm Waterproof Vinyl Flooring SPC adopts a multi-layer composite structure engineered for strength, surface durability, and moisture isolation.

• UV Coating Layer: Provides scratch resistance and stain protection

• Wear Layer: Transparent PVC layer ensuring abrasion resistance

• Decor Film: High-definition printed design layer

• SPC Core Layer: Calcium carbonate + PVC compound for rigidity

• Balance Layer: Enhances structural stability and flatness

• Optional IXPE/EVA Backing: Acoustic insulation and comfort underfoot

Manufacturing Process

The manufacture of 3.5mm Waterproof Vinyl Flooring SPC requires controlled extrusion, precise lamination, and standardized finishing processes.

1. Raw Material Compounding: High-speed mixing of PVC resin, calcium carbonate, stabilizers, and modifiers

2. SPC Core Extrusion: Twin-screw extruder forming rigid core sheets

3. Hot Press Lamination: Integration of wear layer, décor film, and SPC core

4. Cooling & Calibration: Controlled cooling to ensure thickness accuracy

5. UV Coating & Curing: Multi-pass UV application for surface durability

6. Precision Cutting: CNC cutting to plank or tile dimensions

7. Click Profile Milling: Automated locking system machining

8. Quality Inspection: Dimensional, mechanical, and visual checks

Industry Comparison

Application Scenarios

3.5mm Waterproof Vinyl Flooring SPC is widely specified in projects requiring thin profiles and moisture resistance.

• Distributors & Wholesalers: High-volume standardized flooring supply

• Construction Contractors: Fast-install renovation projects

• Commercial Developers: Offices, retail, and hospitality interiors

• Residential Projects: Apartments, kitchens, and bathrooms

• Importers: Private label and OEM flooring programs

Core Pain Points and Solutions

• Subfloor Irregularities: Rigid SPC core bridges minor imperfections

• Moisture Exposure: Waterproof formulation prevents swelling

• Thickness Limitations: 3.5mm profile suits renovation constraints

• Installation Speed: Click-lock system reduces labor time

Risk Warnings and Mitigation

Incorrect selection or installation may impact flooring performance.

• Risk of joint failure if subfloor flatness exceeds tolerance

• Surface damage from improper rolling loads

• Color variation without batch control

• Mitigation: enforce subfloor standards, specify wear layer thickness, and implement batch traceability

Procurement and Selection Guide

1. Confirm required thickness and wear layer class

2. Verify SPC core density and formulation stability

3. Check applicable standards (ISO, EN, ASTM)

4. Evaluate click-lock profile strength

5. Request abrasion, slip, and fire test reports

6. Review packaging, palletization, and logistics

7. Assess OEM capability and quality consistency

Engineering Case Example

In a 12,000 m² mixed-use residential renovation project, 3.5mm Waterproof Vinyl Flooring SPC was installed over existing ceramic tiles. The rigid core allowed direct installation without demolition, reducing construction time by 30% and achieving consistent acoustic and moisture performance across all units.
