Brand: RaxPanel

PVC Foam Sandwich Panel

PVC Foam Sandwich Panel is a composite material constructed with a polyvinyl chloride foam core laminated between rigid facing materials, designed to provide structural performance and functional properties in a lightweight format. The core material consists of closed-cell PVC foam, which contributes to the panel’s low density and consistent cellular structure. External skins include materials such as fiberglass, aluminum, or finished wood, bonded using industrial adhesives to form a unified, durable structure.

The panel offers strength relative to weight, ease of processing, and suitability for various environments. The closed-cell foam provides resistance to moisture and chemicals, while the composite build supports structural rigidity and impact resistance. Mechanical properties include compressive strength and dimensional stability, with the foam core maintaining integrity across different temperatures.

Application scenarios span building decoration, interior partitions, exhibition stands, wall paneling, and lightweight furniture. The material is employed in transportation for truck bodies, trailers, and recreational vehicles, where its insulation properties and weight efficiency prove beneficial.

Customization options include panel thickness, skin material, surface finish, and color choices. Standard thickness options include 16mm, 20mm, and 25mm, with widths up to 1200mm. Custom dimensions can reach 12 meters in length and 3.2 meters in width, accommodating diverse project requirements.

PVC Foam Sandwich Panel Selection & Engineering Guide

PVC Foam Sandwich Panel combines high-strength composite skins with an engineered core to deliver superior thermal insulation, structural rigidity, and long-term durability for commercial applications.

💡 Pro Tip: Delamination Prevention Under Thermal Cycling
At RaxPanel, we utilize automated vacuum lamination with high-performance two-component polyurethane adhesives to ensure a bond strength that absorbs differential thermal expansion without micro-delamination.

1. How to Choose the Right Skin Alloy and Thickness

Outer skin selection governs mechanical impact resistance, corrosion barriers, and structural stiffness across different operating environments.

2. How Well Does the Core Insulate and Withstand Heavy Loads?

The core material acts as the web in an I-beam structure, handling shear stress and maintaining thermal R-value insulation:

Performance Metric	RaxPanel Engineering Standard	Application Advantage
Skin Spec	Engineered Aluminum / Composite Skin (0.3mm – 2.0mm / 1.0-3.0mm)	High tensile and impact resistance against road debris
Thermal Conductivity	~ 0.022 – 0.035 W/m·K	Consistent thermal R-value energy savings
Adhesive Layer	Two-component PU / Epoxy Adhesive	Delamination-free performance under thermal freeze-thaw cycles

3. Which Surface Finish Will Protect Your Panels for 20+ Years?

Factory roller coating specifies long-term color stability, UV protection, and resistance against industrial pollutants or marine salt spray.

4. How Fire-Safe and Soundproof Are These Panels?

🛡️ Compliance & Acoustic Isolation:

Fire Safety: Formulations comply with EN 13501-1 Class B-s1,d0 and GB8624 Class B1 building fire safety standards.
Sound Damping: Composite core attenuates noise transmission by 24 dB to 30 dB relative to solid metal sheets.

5. Where Are PVC Foam Sandwich Panels Most Commonly Installed?

🚚 Vehicle Bodies & Trailers

Lightweighting and high-impact structural strength for mobile fleets.

🏢 Cold Rooms & Building Envelopes

Thermal R-value insulation and moisture-proof building enclosures.

6. How to Cut, Groove, and Seal Edges During Installation

Panels process easily on-site using standard CNC machinery, routers, or specialized edge profiles for airtight moisture sealing.

Frequently Asked Questions (FAQS)

1. What are the standard panel thicknesses, maximum lengths, and width options available for PVC Foam Sandwich Panels?

Standard panel thicknesses range from 10mm up to 150mm. Standard widths include 1000mm, 1220mm, and 1500mm, with maximum single-sheet lengths up to 5800mm (5.8m) to fit ocean freight container shipping dimensions.

2. What are the primary engineering benefits of using PVC Foam Sandwich Panels?

PVC Foam Sandwich Panels deliver an exceptional stiffness-to-weight ratio, rot-proof moisture resistance, reliable thermal insulation, and dynamic fatigue endurance for high-stress applications.

3. How do these composite panels perform under high humidity and outdoor weathering?

The closed-cell core prevents water logging and condensation absorption, while pre-painted skins provide a 20+ year weatherability barrier against UV degradation.

4. What fire safety ratings and quality certifications do these composite panels meet?

Flame-retardant formulations meet EN 13501-1 Class B-s1,d0 and GB8624 Class B1 fire performance standards. Manufacturing quality is governed under ISO9001 management systems, with raw material performance verified under SGS and CE testing.

5. What surface coating options are available for exterior UV protection?

70% PVDF Fluorocarbon Coating PVDF coating provides a 20+ year exterior weatherability warranty against UV fading and acid rain. FEVE offers high gloss retention, while PE coating is cost-effective for indoor partitions.

6. Can these composite panels be CNC grooved, bent, or edge-sealed on-site?

Yes. Pre-painted skins can be V-grooved at 90° or 135° on the reverse side using standard CNC routers or hand tools, allowing manual edge folding into architectural cassettes without surface paint cracking.

7. How are large panel shipments packaged to prevent freight damage during ocean transit?

Panels are packed with protective PE film on both skins, separated by inter-sheet foam layers, and secured on heavy-duty export wooden pallets or CKD steel crates to prevent shipping damage during 20ft and 40ft container freight.
