Panel Sándwich para Edificaciones

Building sandwich panels combine a polypropylene honeycomb core with outer skin layers, typically Continuous Fiber Reinforced Thermoplastic (CFRT) sheets. The honeycomb structure, approximately 95% air, delivers exceptional strength-to-weight ratios while maintaining structural integrity across temperatures from -40°C to +80°C.

The polypropylene core fuses to skin layers through glue-free bonding under heat and pressure, eliminating adhesives. CFRT skins may include multiple unidirectional tape layers and protective films for enhanced bonding and scratch resistance. Panels resist moisture, corrosion, and chemicals while remaining fully recyclable.

Available thicknesses range from 5mm to 120mm, with maximum dimensions reaching 2.8 meters wide by 12 meters long. Core densities typically span 60-100 kg/m³, with compressive strength values from 1.47 to 2.6 MPa. The thermoplastic nature enables CNC machining, thermoforming, and bending without delamination concerns.

Applications include commercial vehicle bodies, mobile homes, transportation flooring, marine decks, architectural partitions, and building formwork. Surface treatments offer glossy or matte protective films, embossing, and custom paint coatings. UV protection through carbon black additives maintains mechanical properties in outdoor environments.

Panel Aislante Snap N Lock

An insulated panel system featuring a patented interlocking joint design. This allows for fast, easy installation without additional fasteners. The unique locking mechanism creates a continuous, thermally efficient, and airtight seal, ensuring high structural performance and insulation continuity between panels.

Panel Sándwich de Acero Inoxidable

A high-performance panel featuring stainless steel skins bonded to a rigid insulating core, engineered for maximum durability. Its defining characteristics are superior corrosion resistance, a non-porous hygienic surface that is easy to clean, and excellent fire resistance properties for demanding environments.

Panel Aislante Z Lock

Z Lock Insulated Panel is a three-layer sandwich construction featuring corrugated steel sheets on both sides with an insulating foam core, typically EPS (expanded polystyrene). The distinctive Z-shaped interlocking system creates secure, wind-resistant connections between panels through a spike-and-groove mechanism.

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
