1. Core PVC Board Specifications Explained
PVC board (polyvinyl chloride board) is one of the most widely used engineering plastics, applied across chemical corrosion protection, advertising signage, architectural decoration, and electroplating equipment. Understanding PVC board specifications is the first step in procurement and the foundation for judging whether a product fits the intended scenario. Common spec parameters include thickness, dimensions, density, color, and execution standards, each of which directly affects PVC board price.
1.1 Thickness Range
Thickness is the most central parameter in the PVC board spec system. The mainstream thickness range on the market is 1mm to 50mm, with some custom products reaching 60mm or more. Common thickness steps include 1mm, 2mm, 3mm, 5mm, 8mm, 10mm, 15mm, 20mm, 25mm, and 30mm. Thicker boards offer better mechanical strength, impact resistance, and pressure resistance, but PVC board prices rise linearly. Selection should balance load requirements, processing method, and budget.
1.2 Standard Dimensions (Length x Width)
The standard PVC board size is 1220mm x 2440mm (4ft x 8ft), the most common panel spec among domestic manufacturers. Other available sizes include 1000mm x 2000mm, 1250mm x 2500mm, 1500mm x 3000mm, and 2000mm x 4000mm, with some imported boards reaching 2050mm x 3050mm. Large-format boards suit applications requiring wide seamless joints, such as chemical corrosion lining or large signage.
1.3 Density and Material Classification
Rigid PVC board (UPVC) has a density of about 1.38-1.45 g/cm³, while flexible PVC board ranges from 1.16-1.35 g/cm³. Density reflects material compactness and is a key basis for judging whether a formulation meets standard. Some low-priced PVC boards cut costs by adding excess calcium carbonate filler, resulting in higher density but degraded mechanical performance, poor weather resistance, and easy brittleness—buyers should be especially cautious.
2. Spec Differences: Rigid vs. Flexible PVC Board
2.1 Rigid PVC Board Specifications
Rigid PVC board, also called UPVC board, offers excellent acid and alkali resistance, corrosion resistance, and electrical insulation. It is the main material for chemical corrosion equipment, electroplating tanks, ducts, and welded components. Common rigid PVC board dimensions are 1220mm x 2440mm, with thickness mostly 2-30mm, in gray or white. Industrial-grade rigid board follows GB/T 22789.1, requiring tensile strength ≥45MPa and impact strength ≥5kJ/m².
2.2 Flexible PVC Board Specifications
Flexible PVC board is elastic and commonly used for gaskets, corrosion linings, and workbench mats. Thickness is typically 1-10mm, with panel sizes of 1000mm x 2000mm or custom rolls. Spec selection for flexible boards focuses more on hardness (Shore A, typically 60A-90A) and temperature range, which must be precisely matched to the contacting medium and operating temperature.
3. PVC Board Price per Square Meter
3.1 Price Factors
PVC board price is influenced by multiple factors, mainly:
- Raw material cost: PVC resin powder price fluctuates with international oil prices
- Spec thickness: thicker boards use more material per square meter
- Brand and manufacturer: well-known brands carry significant premium, import vs. domestic price gap can reach 30%-100%
- Execution standard: GB-standard boards cost 10%-20% more than enterprise-standard boards
- MOQ: large-volume orders get tiered pricing
3.2 Market Reference Prices
Taking domestic rigid PVC board as an example, common price ranges are as follows (for reference only, subject to quotation):
- 2mm: about 25-40 RMB/m²
- 5mm: about 50-75 RMB/m²
- 10mm: about 100-150 RMB/m²
- 20mm: about 200-280 RMB/m²
- 30mm: about 300-420 RMB/m²
Imported brands (such as Swiss AGRU, German Röchling) are typically double or higher. Flexible PVC board prices are relatively lower, with 1-3mm commonly quoted at 15-35 RMB/m².
4. PVC Board Buying Tips and Manufacturer Selection
Beyond specs and price, focus on the following when selecting PVC board:
- Check test reports: require third-party reports and verify key indicators like density, tensile strength, and Vicat softening temperature
- Inspect appearance: surface should be flat and smooth, free of bubbles, cracks, and impurities, with uniform color
- Verify spec accuracy: thickness tolerance should be controlled within ±0.1-0.3mm; over-tolerance affects downstream processing
- Batch stability: large orders should come from the same batch to avoid color and performance variation
- After-sales capability: reputable manufacturers offer technical support and warranty

5. FAQ
Q1: Can PVC board dimensions be customized?
Yes. Beyond standard specs, most manufacturers support custom cutting, with maximum panel size up to 2m x 4m and thickness up to 60mm or more. MOQ and pricing may differ, so confirm with the supplier in advance.
Q2: What is a reasonable PVC board price per square meter?
For domestic rigid boards 2-20mm thick, prices typically range from 25-280 RMB/m², depending on thickness, brand, and standard. Products priced 20% below market should raise quality concerns.
Q3: How to distinguish rigid from flexible PVC board?
The most intuitive method is a press test. Rigid boards have no elasticity and produce a crisp sound when tapped; flexible boards are elastic and bendable. Density data also helps—rigid boards usually exceed 1.38 g/cm³.
Q4: What national standard does PVC board follow?
Rigid PVC board follows GB/T 22789.1-2008. Flexible boards can reference relevant industry standards. The execution standard should be specified in the contract.
Q5: Can PVC board be used in food-grade scenarios?
Ordinary industrial-grade PVC board is not suitable for food contact. Food-grade applications require PVC material compliant with GB 4806.7, along with a food-contact test report. Industrial boards must not be mixed with food-grade ones.
6. Summary and Action
The PVC board spec system appears simple but involves multi-dimensional parameters including thickness, size, density, material, standard, and price. Before procurement, clarify the use scenario and performance requirements, then evaluate PVC board price and manufacturer qualifications together to buy material that meets both technical needs and cost efficiency.
