Panel sándwich de HDPE

High-Density Polyethylene (HDPE) sandwich panels feature a honeycomb core construction that delivers exceptional strength-to-weight performance for industrial applications. The HDPE honeycomb core provides outstanding moisture and chemical resistance while maintaining structural integrity through advanced extrusion and proprietary bonding technology.

These lightweight panels combine low mass with high structural performance, making them ideal for weight-critical applications. Their inherent corrosion resistance ensures reliable performance in demanding environments. Manufacturing facilities offer extensive customization for size, thickness, and cell structure parameters to meet specific project requirements.

Standard dimensions reach 3000 mm length and 1500 mm width, with thicknesses from 1.5 mm to 400 mm. Honeycomb cell diameters range from 3.5 mm to 10 mm, with custom specifications available. Applications span automotive components, logistics packaging, construction wall panels, flooring systems, and commercial air flow diffusers.

Comprehensive quality control systems oversee the complete manufacturing process from production through final testing and packaging. Standard delivery time for mass production orders is 10-15 working days, with products shipped in protective plywood cases or pallets. Strategic port location enables efficient global logistics and flexible international delivery terms.

HDPE Sandwich Panel Selection & Engineering Guide

Selecting the right specification for HDPE Sandwich Panel 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.

💡 Consejo profesional: Prevención de la delaminación bajo ciclos térmicos
En RaxPanel, utilizamos laminado automático al vacío con adhesivos de poliuretano bicomponente de alto rendimiento para garantizar una resistencia de unión que absorbe la expansión térmica diferencial sin microdelaminación.

1. Cómo elegir el aleación y espesor del revestimiento adecuado

La selección del revestimiento externo determina la resistencia al impacto mecánico, las barreras contra la corrosión y la rigidez estructural en diferentes entornos operativos.

2. ¿Qué tan bien aísla y soporta cargas pesadas el núcleo?

The core material handles shear stress and maintains thermal R-value insulation across operating temperature ranges:

Métrica de rendimiento	Estándar de ingeniería de RaxPanel	Ventaja de aplicación
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 HDPE Sandwich Panels 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 HDPE 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 HDPE Sandwich Panels?

HDPE 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. ¿Estos paneles compuestos pueden ser canalizados, doblados o sellados en los bordes en sitio con CNC?

Sí. Las pieles pre-pintadas se pueden canalizar en V a 90° o 135° en el lado opuesto usando routers CNC estándar o herramientas manuales, permitiendo el doblado manual de bordes en casetes arquitectónicos sin agrietar la pintura superficial.

7. ¿Cómo se empaquetan los grandes envíos de paneles para prevenir daños durante el tránsito marítimo?

Los paneles se empaquetan con película protectora de PE en ambas pieles, separados por capas de espuma intercaladas, y asegurados sobre palets de madera de exportación de alta resistencia o contenedores de acero CKD para prevenir daños durante el flete en contenedores de 20 pies y 40 pies.
