Panel Sándwich Espumoso PET

PET Foam Sandwich Panel is a composite material designed for structural applications where low weight and high performance are required. It features a polyethylene terephthalate (PET) foam core sandwiched between rigid facings such as fiberglass, aluminum, or composite sheets. The closed-cell foam core contributes to structural integrity and insulation properties, while the facings provide strength, impact resistance, and a finished surface.

The panel offers key advantages including lightweight characteristics for easier handling and installation, resistance to moisture and environmental conditions, and energy efficiency through thermal insulation. Its durability and structural performance make it suitable for long-term applications requiring reliability.

Available in customizable dimensions with thicknesses from 10 mm to 120 mm, widths up to 3.2 meters, and lengths up to 12 meters, the panel can be tailored to specific project needs. Foam core density and facing materials can be selected to meet required strength and insulation levels.

Application scenarios include marine equipment, transportation vehicles, wall panels, partitions, and flooring in recreational vehicles, modular constructions, and industrial settings. The panel can be processed through CNC cutting, drilling, and shaping, with options for lamination, trimming, and various surface treatments to meet specific requirements.

💡 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?

El material del núcleo actúa como el alma de una viga en I, soportando esfuerzos cortantes y manteniendo el aislamiento térmico (valor R):

Métrica de rendimiento	Estándar de ingeniería de RaxPanel	Ventaja de aplicación
Especificación del revestimiento	Engineered Aluminum / Composite Skin (0.3mm – 2.0mm / 1.0-3.0mm)	Alta resistencia a la tracción y al impacto contra escombros de la carretera
Thermal Conductivity	~ 0.022 – 0.035 W/m·K	Ahorro de energía con valor térmico R constante
Capa adhesiva	Adhesivo PU / epoxi de dos componentes	Rendimiento libre de delaminación en ciclos térmicos de congelación-descongelación

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 PET 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 PET 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 PET Foam Sandwich Panels?

PET 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?
