High-Density PVC Foam Board
Product Overview and Applications
High-density PVC foam board is a rigid, closed-cell sheet made from extruded polyvinyl chloride. Its density of 0.7–0.9 g/cm³ provides stiffness, impact resistance, and load-bearing strength. The smooth surface supports printing, painting, and lamination. Its closed-cell core also resists water, rot, and everyday cleaning.
Typical uses include cabinets, furniture, wall panels, and other moisture-prone applications. CNWALL produces the board with a co-extrusion process. One extruder forms the foamed core, while a second extruder creates dense outer skins on both faces.

0.7–0.9 g/cm³ High-Density PVC Foam Board
Advantages
Exceptional nail-holding power and dimensional stability, thanks to its dense, closed-cell core.
High surface hardness, smoothness and gloss—ideal for direct routing, slotting and bending without cracking.
Uniform, tight internal structure that resists delamination or warping.
A fine “finger-scrape” finish: surface tests leave no marks, ensuring a premium look and feel.
Compared with conventional single-extrusion PVC foam, co-extruded high-density boards require two synchronized extruders and more complex tooling, which raises production cost but delivers superior mechanical performance and surface quality.
PVC Foam Board Co-Extrusion Technology
High-Density Production Process
1. Raw Materials
- PVC resin
- Calcium carbonate powder
- Bamboo-wood fiber
- Carbon black powder
- Clean recycled PVC (regrind)
- Processing additives (stabilizers, lubricants, foaming agents, impact modifiers)
2. Equipment
- Extruder A (twin-screw) for core layer
- Extruder B (twin-screw) for skin/co-extrusion layer
- Co-extrusion die head (specialized PVC board die)
- Water cooling tank
- Slitter and edge-trimming station
- Traction (haul-off) rollers
- Automatic palletizing/off-loading unit
3. Production Process
Batching & Pre-Mixing
- Weigh each component according to your formula (e.g. 60–70% PVC resin, 20–30% calcium, 5–10% fiber, remainder additives & regrind).
- Pre-blend dry powders and fibers in a ribbon blender or tumble mixer for uniformity.
Feeding & Extrusion
- Feed the core-layer blend into Extruder A. Set barrel zones to ~160–180 °C and screw speed for good dispersion.
- Feed the skin-layer blend into Extruder B under similar temperature profile.
Melting & Mixing
- In each extruder, PVC resin plastifies and shears with fillers/additives. Adjust back-pressure to ensure thorough mixing and de-gassing of volatiles.
Co-Extrusion
- Direct both melts into the co-extrusion die head. The inner melt (core) forms the foam center; the outer melt (skin) forms dense, smooth surfaces.
- Optimize layer thickness ratio (e.g. 80% core / 20% skin) by adjusting extruder throughput.
Sheet Forming
- Extruded melt exits the die in a continuous sheet. Immediately enter the cooling tank.
Cooling & Sizing
- Pass the hot board (180–200 °C) through a series of water baths or spray zones to solidify and fix dimensions.
Trimming & Slitting
- Use a slitter to cut boards longitudinally; trim edges to remove flash.
- Cross-cut to standard 4×8 ft panels or custom lengths via flying-knife cutter.
Haul-Off & Palletizing
- Pull the finished boards through traction rollers to maintain speed control and prevent deformation.
- Automatic off-loader stacks boards onto pallets in bundles; wrap or band for shipment.
4. Quality Control & Tips
- Monitor melt pressure and temperature profiles on both extruders.
- Check board thickness, density (target ≥0.8 g/cm³), surface finish, and dimensional tolerances.
- Test the closed-cell structure and mechanical properties at scheduled intervals.
- Control raw-material moisture to reduce porosity defects.
These checks help maintain uniform density, smooth surfaces, and stable physical performance. Operators adjust material ratios and process settings when results move outside the target range.
Sustainability

ISO 9001 quality procedures guide process control and inspection. We monitor density, dimensions, surface quality, and emissions with production and testing equipment. Our team continues to improve material efficiency, water use, and production consistency.
FAQs of High-density PVC Foam Board
What is PVC foam board?
- A lightweight, rigid sheet made from polyvinyl chloride (PVC) with a closed-cell foam core.
- Typical density: 0.4–0.6 g/cm³.
- Smooth surface, easy to cut, rout, glue, and paint.
- Common applications: signage, exhibition displays, point-of-sale stands, model making, indoor partitions.
What is high density PVC foam board?
- Similar closed-cell PVC construction, but formulated for a higher core density (usually ≥0.7 g/cm³).
- Denser, stronger foam structure with reduced cell size.
- Offers improved mechanical properties (stiffness, impact resistance).
- Often used where greater durability and dimensional stability are required.
What are the key differences between standard PVC foam board and high density PVC foam board?
- Density & Weight
- Standard: 0.4–0.6 g/cm³ (lighter).
- High density: ≥0.7 g/cm³ (heavier, more substantial feel).
- Strength & Rigidity
- Standard: Suitable for general-purpose indoor use.
- High density: Higher flexural strength and impact resistance.
- Surface Finish
- Standard: Smooth but more prone to denting under stress.
- High density: Tighter cell structure yields a firmer, more scratch-resistant surface.
- Dimensional Stability
- Standard: Slightly more prone to warp or bow in large panels.
- High density: Superior flatness over time and under load.
- Cost
- Standard: More economical for budget-sensitive projects.
- High density: Higher material cost, justified by enhanced performance.
- Typical Applications
- Standard: Indoor signage, point-of-sale displays, model making.
- High density: Outdoor signage (with UV coating), industrial fixtures, CNC machining parts, marine interiors.
How do I choose between them?
- Budget & Weight Constraints: If weight savings and lower cost are priorities, choose standard PVC foam board.
- Durability & Load-Bearing Needs: For heavy-duty, high-traffic, or structural applications, high density PVC foam board is the better choice.
- Finish Requirements: If you need a firmer surface for fine machining or printing, opt for the high density option.
Can both types be painted or laminated?
- Yes. Both standard and high density PVC foam boards accept paints, vinyl wraps, and laminates equally well.
- Pre-treatment (light sanding, primer) is recommended for best adhesion and finish.
High-density PVC foam board excels as a modern panel solution for furniture, cabinets and wall finishes. Its fine, closed-cell structure delivers exceptional strength and impact resistance while remaining lightweight and easy to machine—ideal for sleek wardrobe doors, kitchen cabinet carcasses and decorative wall panels.
The board’s ultra-smooth surface accepts paints, laminates and veneers with perfect adhesion, so you can achieve a flawless finish in any décor style.
