China PVC Plastic Flooring Sheets Factory

PVC plastic flooring sheets are produced from polyvinyl chloride resin blended with plasticizers, stabilizers, and filler materials to achieve flexibility, durability, and resistance to moisture and chemicals. The sheets are extruded or calendared to uniform thickness, then cooled and cut to size for downstream processing.

Material Composition and Performance Characteristics

The base formulation typically contains 55‑65 % PVC resin, 20‑30 % plasticizer (such as DINP or DOTP), 5‑10 % calcium carbonate filler, and additives for UV stabilization, flame retardancy, and antimicrobial protection. This composition yields a density of approximately 1.4 g/cm³, a tensile strength of 20‑25 MPa, and an elongation at break of 150‑250 %.

• Density: 1.35‑1.45 g/cm³ (measured per ASTM D792)
• Tensile strength: ≥20 MPa (ASTM D638)
• Elongation at break: 150‑250 % (ASTM D638)
• Hardness (Shore A): 85‑95
• Water absorption: <0.5 % after 24 h immersion (ASTM D570)

Typical Technical Specifications

Industrial Applications and Rationale

In manufacturing plants, the flooring must resist oil, coolant, and frequent impact from heavy equipment. PVC sheets with a reinforced wear layer and optional anti‑static additives provide a seamless surface that prevents liquid ingress and reduces dust accumulation. In cleanroom environments, the low outgassing and ease of welding seams meet ISO Class 5‑8 requirements when installed with heat‑welded joints. Retail and hospitality sectors benefit from the material’s acoustic dampening (impact sound reduction up to 18 dB) and ability to retain color stability under UV exposure.

Customization Options

Manufacturers can adjust the formulation and processing parameters to meet specific project needs:

• Thickness: 1.5 mm to 6.0 mm in 0.5 mm increments
• Wear layer: 0.10 mm to 0.50 mm (PU‑coated or plain PVC)
• Surface finish: smooth, embossed (linen, stone, wood grain), or textured for slip resistance
• Color: custom Pantone matching or standard RAL/NCS palettes
• Additives: anti‑static (carbon fiber), antimicrobial (silver ion), UV stabilizers, flame retardants
• Edge treatment: straight, beveled, or with integrated locking profile for interlocking installation

Quality Assurance and Inspection

Quality control begins with incoming resin testing for melt flow index and purity. During extrusion, thickness is monitored via laser gauges with a tolerance of ±0.05 mm. Post‑production, each batch undergoes:

• Dimensional verification (width, length, thickness)
• Tensile and elongation testing on five specimens per roll
• Wear resistance via Taber abrasion (cycles to failure)
• Slip resistance measurement (pendulum tester)
• Visual inspection for surface defects, discoloration, and foreign inclusions

Results are recorded in a traceable batch record; any deviation beyond specification triggers rework or rejection.

Packaging and Logistics

Finished sheets are rolled on cardboard cores with an inner diameter of 76 mm, wrapped in polyethylene film to protect against moisture, and placed on pallets equipped with corner protectors. Each pallet is strapped and labeled with lot number, dimensions, and handling instructions. For overseas shipments, containers are fitted with desiccant bags and temperature monitors to maintain product integrity.

Frequently Asked Questions

• Can dimensions be customized? Yes, width, length, and thickness can be adjusted according to project specifications; tooling changes may affect lead time.
