PC Honeycomb Core

The PC Honeycomb Core combines polycarbonate thermoplastic material in a honeycomb structure for sandwich panel construction and industrial applications. This recyclable core material resists moisture, corrosion, and chemicals while operating effectively from -40°C to +120°C.

Manufacturing utilizes advanced extrusion lines and proprietary bonding technology. Standard sizes include 1220x2440mm and 1200x2400mm, with maximum dimensions reaching 3000mm length and 1500mm width. Thickness ranges from 1.5mm to 400mm, cell sizes from 3.5mm to 12mm, and density between 65-200 kg/m³. All parameters including color and skin applications are customizable.

The core delivers high strength-to-weight ratio with compressive strength of 2.4 MPa and shear strength of 0.6 MPa (3.5mm cells). Additional properties include high light transmission, sound insulation, and smooth inner walls promoting air or liquid permeability.

Applications span air and water purification systems as photocatalyst and activated carbon carriers, clean room ventilation devices, automotive and rail interior panels, construction wall panels and flooring, logistics packaging, commercial air diffusers, and chemical industry equipment including cooling towers.

    PC Honeycomb Core Selection & Engineering Guide

    Selecting the right specification for PC Honeycomb Core depends on matching structural load requirements, environmental exposure, and thermal R-value insulation goals. At RaxPanel, our engineering team manufactures high-performance composite panels to deliver durable, moisture-resistant, and energy-efficient solutions for industrial and commercial projects worldwide.

    💡 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 handles shear stress and maintains thermal R-value insulation across operating temperature ranges:

    Performance Metric RaxPanel Engineering Standard Application Advantage
    Outer Skin Spec Pre-Painted Aluminum / GRP Sheet (0.3mm – 2.0mm) High tensile strength and corrosion resistance
    Thermal Conductivity ~ 0.020 – 0.038 W/m·K Consistent R-value insulation & energy savings
    Bonding Adhesive Two-Component Polyurethane / Epoxy Adhesive Delamination-free performance under 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 PC Honeycomb Cores Most Commonly Installed?

    🏢 Commercial & Industrial Buildings

    Exterior wall cladding, cleanroom partitions, and insulated roof envelopes.

    🚚 Cold Storage & Transport Fleets

    Refrigerated truck bodies, cold storage rooms, and RV composite walls.

    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 PC Honeycomb Cores?
    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 PC Honeycomb Cores?
    PC Honeycomb Cores 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.
