Despite hundreds of specifications, the cost structure of extrusion panels is similar.

PVC Panel Cost Breakdown

Component	Cost Contribution
PVC Resin	40–60%
CaCO₃ Filler	20–40%
Stabilizers	5–10%
Color Masterbatch / Film	1–5%
Labor, Energy, Machine	10–20%

WPC Board Cost Breakdown

Component	High-Quality	Low-Cost
Plastic (PP/PE/PVC)	High	Low
Wood Flour	Low	High
CaCO₃	Low	High
Coupling Agent	Sufficient	Reduced / Removed
UV Stabilizer	Sufficient	Removed

📌 Tip for importers: Resin is expensive, while CaCO₃ filler and wood flour are cheap. Lower-cost panels often reduce resin content and increase filler, which directly affects durability.

2. High-Quality vs Low-Cost PVC & WPC Panel Formulation

High-Quality PVC Panel

• PVC resin content: high
• CaCO₃ filler: 20–35%
• Stabilizers: premium calcium-zinc
• Surface: smooth and dense
• Flexibility & impact resistance: excellent

Benefits:

• No cracking or yellowing
• Longer lifespan
• Ideal for Europe, high-end interior projects

Low-Cost PVC Panel

• CaCO₃ filler: 50–70%
• PVC resin content: low
• Stabilizers: cheap alternatives
• Appearance: dense but fragile

Common Problems:

• Brittle and prone to cracking
• Poor weather resistance
• Chalky surface over time

Why some purchasers choose it:

Suitable for low-cost markets such as Middle East and Africa

15–40% cheaper

3. WPC Board Formulation and Its Impact

High-Quality WPC Boards

• Plastic content: high
• Wood flour: moderate
• Coupling agents: sufficient
• UV and antioxidant additives: included

Performance:

• Low water absorption
• No swelling or warping
• Fade-resistant
• Outdoor lifespan: 8–15 years

Low-Cost WPC Board

• Wood flour: excessive
• Plastic content: low
• CaCO₃: high
• UV stabilizers: absent or minimal

Common Problems:

Short lifespan and poor outdoor performance

Swelling and surface warping

Cracking and fading within 6–12 months

4. High Density ≠ High Quality

Some suppliers claim:

“Our panel is heavier, so it’s better quality.”

This is misleading. High density usually means excessive CaCO₃ filler.
Resin content, formula balance, and stabilizer quality are the true indicators of premium performance.

5. How PVC & WPC Panel Formulation Influences Final Price

• High-Resin Formula
• Costly due to expensive PVC resin
• Premium stabilizers and UV additives add to cost
• Slower extrusion speed for better quality
• Low-Cost Formula
• Cheap filler like CaCO₃ increases density but lowers quality
• Less resin reduces cost
• No UV additives
• Faster production
• Result: Panels with the same dimensions can differ 20–60% in price depending on formulation.

6. Questions Importers Should Ask Suppliers

1. What is the PVC resin percentage?
2. What is the CaCO₃ filler percentage?
3. Which stabilizers are used (Ca-Zn or cheaper alternatives)?
4. Are UV stabilizers included?
5. Can you provide a formulation sheet?
6. What is the density, and why?
7. What application is this formula designed for?

Suppliers who refuse to answer often rely on low-end formulas.

7. Recommended Product Solutions (Example: PVC & WPC Panel Formulation of ZALA Decoration)

• Premium PVC Ceiling Panels: low CaCO₃, high resin
• WPC Fluted Panels: UV-resistant formula
• Outdoor WPC Decking: high plastic, low wood flour
• Semi-Outdoor Wall Cladding: 3D surface film

Designed for purchasers seeking:

• Lower claim rates
• Longer lifespan
• Better installation experience
• Stable repeat orders

8. Final Advice about PVC & WPC Panel Formulation for Importers

If a price looks too good to be true, it usually is.

PVC & WPC Board Formulation determines performance. Performance determines value. Value determines repeat business.

Importers who understand PVC/WPC formulations make smarter sourcing decisions, reduce complaints, and build stronger customer trust.
