7 Reasons Why PVC Foam Board is Replacing Plywood and MDF

In the last 30 years, I have watched the furniture and advertising industries struggle with one major issue: Moisture.

Plywood rots. MDF swells. Metal rusts.

If you manufacture kitchen cabinets, bathroom vanities, or outdoor signage, you know that water is your enemy. The solution is not better paint; it's better material.

Enter PVC Foam Board (specifically the Celuka and Co-extruded grades). It looks like wood, works like wood, but lasts like plastic. At Jinbao Plastic, we are now shipping over 500 containers a year to factories that are completely ditching traditional timber.

Here are the 7 undeniable benefits of switching to Jinbao PVC Foam Board.

1. 100% Waterproof (No Swelling, Ever)

This is the biggest selling point. Unlike wood, PVC is a closed-cell polymer. You can submerge a Jinbao PVC cabinet board in a swimming pool for a year, and it will not absorb a single drop.

• Application: Bathroom vanities, yacht interiors, and outdoor kitchen cabinets.

2. Termite and Pest Proof

In humid regions (like Southeast Asia, the Middle East, and South America), termites destroy wooden furniture in months. PVC is inorganic—insects cannot eat it. It guarantees a lifetime warranty for your products against pest damage.

3. Fire Retardant (Class B1 Safety)

Safety is non-negotiable. Jinbao’s PVC boards are self-extinguishing.

• The Tech Spec: We meet the GB 8624-2012 Class B1 standard. If a fire starts, the board will not feed the flames; it carbonizes and stops burning the moment the fire source is removed.

4. Lightweight but Rigid

Shipping heavy plywood is expensive. PVC foam board is significantly lighter (Density 0.4 - 0.7 g/cm³), making it cheaper to transport and easier for installers to handle on-site.

• Comparison: A 18mm sheet of MDF weighs ~40kg. A 18mm sheet of Jinbao PVC Celuka weighs only ~23kg.

5. Excellent Weather Resistance (UV Stable)

For signage makers, fading is a nightmare. Our UV-Stabilized white boards resist yellowing under direct sunlight. Unlike standard foam core which crumbles, rigid PVC holds up against rain, wind, and fluctuating temperatures.

6. Easy Fabrication (No Special Tools Needed)

You don't need new machinery to switch to PVC. It cuts, drills, nails, and screws just like wood.

• Pro Tip: Because it has no grain, you get cleaner cuts with no splintering. It also holds screws tighter than particle board.

7. Paintable & Laminate-Friendly

Want a wood grain finish? Or a high-gloss color?

• Direct Print: Perfect for UV flatbed printing (advertising).

• Lamination: Easily adheres to PVC film, HPL, or acrylic surfaces (furniture).

• Painting: Compatible with automotive-grade paints for a premium finish.
