3. Manufacturing Process of PVC soft sheet (With Flow Diagram)

1 High-Purity Raw Material Selection
Premium PVC resins (SG5-SG8), plasticizers (DOP/DOA/Eco), and stabilizers undergo strict incoming quality checks (in line with ISO 9001:2015 certification).

2 Compounding & Homogenization
Raw materials are precisely mixed (±0.5% error) and compounded using automatic high-shear mixers to ensure uniform polymer matrix.

3 Extrusion or Calendaring Processing
Compound mix is processed via advanced twin-screw extruders or calendar rollers. Temperature/pressure-controlled forming ensures precise thickness and surface smoothness.

4 Surface Finishing / Optional CNC Machining
Precision cutting, trimming, laser marking, or CNC punching delivers custom sizes and performance-enhanced surfaces.

5 Quality Inspection & Compliance Testing
Each PVC soft sheet batch undergoes dimensional, mechanical, and chemical property tests (ISO 527, ASTM D2240, ROHS/FDA analysis).

6 Packing & Warehousing
Sheets are cut to order, cleaned, and sealed with anti-static/UV-stable materials to prevent shipping/handling damage (compliance: ANSI/ASQC Z1.4).

7. Expert FAQ: Technical FAQ on PVC soft sheet

1. What is the primary material composition of PVC soft sheet?

PVC soft sheet is composed of suspension-polymerized polyvinyl chloride (PVC) resin blended with specific ratios of plasticizers (such as DOP, DOTP, DOA), stabilizers, and optional additives (like UV inhibitors). This formulation imparts high flexibility, chemical resistance, and customizable performance for industrial usage.

2. What surface finishes or textures are available, and how do they affect application?

Common surface options include glossy (high transparency, cleanrooms), matte (anti-glare), embossed (anti-slip or privacy partitions), and patterned (aesthetics). Surface finish impacts slip resistance, light diffusion, and ease of cleaning.

3. What are the typical industry standards PVC soft sheet must meet?

Strict products are manufactured to meet ISO 9001, ASTM D1593 (PVC sheet), ISO 1183 (density), UL94 (flame retardant), FDA 21 CFR (food/medical contact), and EN 13361 (geomembrane application).

4. How is thickness tolerance and flatness ensured for precision-grade sheets?

Thickness is digitally monitored using inline laser micrometers and controlled during extruder/calender operation (tolerance ±0.05mm). Finished PVC soft sheet is inspected via ISO sampling for flatness & warpage, with rejection/safe-conformity rates logged.

5. Can PVC soft sheet be welded or jointed for larger panel applications?

Yes. High-frequency (HF) welding, hot-air, or chemical (solvent) welding is suitable. Joints maintain ≥80% of native tensile strength if performed according to manufacturer's protocol using compatible adhesives or automated welding equipment.

6. What is the recommended installation protocol for chemical or water barrier applications?

PVC soft sheet should be installed over clean, smooth substrates using compatible adhesives or mechanical fasteners. Edges are overlapped 50–75 mm and sealed via thermal or HF welding for leak-tight performance. Installers should align practices with ASTM D4437-20 (geomembrane welding) or local construction code.

7. How does PVC soft sheet perform under aging, UV, and chemical exposure?

Lab tests show >90% mechanical property retention after 10 years outdoor (ISO 4892, QUV test). Typical chemical rating: Class I per ISO/TR 7620 for acids/alkalis; can be further customized with stabilizer packages for harsh chemical or UV environments.
