PET Foam Sandwich Panels - FRP, Aluminum, Steel Facing Options

PET Foam Sandwich Panel

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.

Frequently Asked Questions (FAQS)

What is a PET foam sandwich panel?

A PET foam sandwich panel is a composite material made of polyethylene terephthalate (PET) foam as the core, combined with various skin materials such as FRP, CFRT, aluminum, coated steel, plywood, or PVC. It forms a lightweight, high-strength panel with excellent thermal insulation and sound insulation properties, widely used in industries like transportation and construction.

What are the key advantages of PET foam sandwich panels?

PET foam sandwich panels offer lightweight construction, high mechanical strength, waterproof characteristics, excellent thermal and acoustic insulation, impact and chemical resistance, and full recyclability. They are more durable and environmentally friendly compared to traditional materials like wood or metal.

What are the common applications of PET foam sandwich panels?

PET foam sandwich panels are used in box truck bodies, RVs, buses, trains, marine vessels, building facades, partitions, floors, roofs, and modular furniture. They are ideal for applications requiring lightweight, high-strength, and insulated materials in transportation, construction, and industrial sectors.

What is the thermal insulation performance of PET foam?

PET foam provides effective thermal insulation with a thermal conductivity typically ranging from 0.02 to 0.038 W/m·K. The closed-cell structure enhances insulation properties, making it suitable for temperature-sensitive environments like refrigerated transport or building insulation.

How recyclable are PET foam sandwich panels?

PET foam is fully recyclable; after processes like crushing, cleaning, and melt granulation, the material can be reused to produce new PET foam or other PET products. This supports sustainable practices and reduces environmental impact, aligning with green manufacturing concepts.

Can PET foam sandwich panels be customized?

Yes, RaxPanel offers customization options including thickness (10-150mm), length (up to 12m), width (up to 3.2m), core density (50-300 kg/m³), skin materials, surface treatments, and CNC machining. Embedded reinforcements and specialized coatings are also available to meet specific project needs.
