Structure and Material Composition

3.5mm T Groove Vinyl SPC Flooring is designed with a compact multi-layer structure optimized for thin-profile applications:

• UV Protective Layer: Enhances abrasion resistance and chemical stability

• Transparent Wear Layer: Protects printed décor from mechanical wear

• Decor Film: High-resolution wood or stone visual layer

• SPC Core Layer: Limestone powder and PVC compound providing rigidity

• Bottom Stabilizing Layer: Balances internal stress and improves adhesion

Manufacturing Process

The production of 3.5mm T Groove Vinyl SPC Flooring follows a continuous and controlled industrial process:

1. Raw material batching of PVC resin, calcium carbonate, and stabilizers

2. High-speed mixing to achieve uniform compound dispersion

3. Extrusion forming of SPC core sheets

4. Hot lamination of decor film and wear layer

5. UV surface coating and curing

6. Precision cutting to specified plank dimensions

7. T-groove profiling via CNC edge milling

8. Quality inspection including thickness, density, and locking tolerance

Key equipment includes twin-screw extruders, calendering lines, UV coating systems, and CNC profiling machines.

Industry Comparison

Application Scenarios

3.5mm T Groove Vinyl SPC Flooring is widely specified in the following project types:

       Solution: Specify SPC-approved pressure-sensitive adhesives

• Pain Point: Edge lifting in high-temperature environments
       Solution: Controlled acclimation and perimeter expansion gaps

• Pain Point: Wear layer mismatch with traffic level
       Solution: Select 0.5 mm wear layer for commercial use

Risk Warnings and Mitigation

Potential risks associated with 3.5mm T Groove Vinyl SPC Flooring include:

• Installation on uneven or contaminated subfloors

• Improper adhesive curing time

• Use in environments exceeding temperature limits

Risk mitigation requires strict adherence to subfloor preparation standards, adhesive manufacturer guidelines, and environmental controls.

Procurement and Selection Guide

1. Confirm total thickness and height tolerance requirements

2. Select appropriate wear layer based on traffic classification

3. Verify SPC core density and formulation consistency

4. Review fire rating and compliance certificates

5. Request adhesive compatibility documentation

6. Assess batch color consistency and decor repeat length

7. Conduct on-site mock-up installation testing

Engineering Application Case

In a mixed-use residential renovation project covering approximately 6,800 m², 3.5mm T Groove Vinyl SPC Flooring was installed over existing concrete slabs. The thin-profile system enabled door and skirting retention, reducing demolition costs by over 20% while meeting durability and fire safety requirements.
