High-Performance Closed Cell PE Foam Sheet 1700 x 850mm - Lightweight, Buoyant, and Chemical Resistant

This high-performance closed cell polyethylene (PE) foam sheet is a versatile, lightweight material designed for demanding design, architectural and protective applications. Supplied in a generous 1700 x 850mm sheet size, it offers excellent cushioning, impact absorption and thermal insulation in a compact, easy-to-handle format.

With a closed cell structure for superior buoyancy and low water absorption, this PE foam is also resistant to many common chemicals, making it ideal for use in architectural models, displays, protective inserts, gaskets, seals and lightweight construction details. Available in a selection of thicknesses and in either white or black, it is easy to cut, shape and fabricate to your exact requirements.

Product Features

• Available in a choice of thicknesses, including 2mm, 3mm, 4mm, 5mm and 6mm, plus additional thicker options for more demanding applications.
• Standard sheet size of 1700mm x 850mm, offering ample coverage for cutting multiple components or larger panels.
• Closed cell polyethylene foam construction for low water absorption and consistent cushioning performance.
• Choice of white or black foam to suit aesthetic, visibility or contrast requirements in design and architectural projects.
• Lightweight yet resilient material that is easy to cut, knife, die-cut or router for custom shapes and profiles.
• Good chemical resistance to many oils, solvents and cleaning agents, supporting use in industrial and commercial environments.
• Thermal and acoustic insulation properties suitable for lining, padding and isolation applications.

Key Features and Benefits

• Reduced weight in structures, models and packaging thanks to the foam’s low density, without compromising on protection or rigidity.
• Enhanced moisture performance from the closed cell design, which resists water uptake and supports long-term buoyancy.
• Improved durability and impact protection for delicate items, edges and surfaces, helping to minimise damage in transit or use.
• Streamlined fabrication and installation, as the foam cuts cleanly and can be easily bonded, laminated or shaped to suit complex designs.
• Versatile appearance options with white or black sheets, allowing you to match, contrast or conceal components within your project.
• Cost-effective multi-purpose material that can replace heavier, less adaptable substrates in many design, architectural and protective roles.

Specifications

Applications and Ideal Uses

This closed cell PE foam sheet is suitable for a wide variety of design, architectural, industrial and protective applications where lightweight, cushioning and moisture resistance are important.

• Architectural models, prototypes and concept mock-ups requiring lightweight, easily shaped material.
• Protective packaging inserts, case linings and equipment padding for delicate or high-value items.
• Gaskets, seals and spacers in environments where water and chemical resistance are required.
• Display boards, exhibition panels and point-of-sale elements needing clean edges and stable surfaces.
• Buoyancy aids, flotation components and moisture-resistant liners in marine or wet-area applications.

Frequently Asked Questions

Can I cut and shape the PE foam sheet using standard workshop tools?

Yes, the foam can be cut and shaped using common tools such as sharp knives, hot wire cutters, scissors for thinner gauges, or saws and routers for thicker sheets. Always use a sharp blade and support the material properly for clean, accurate edges.

Is this closed cell PE foam suitable for outdoor use?

The closed cell structure and chemical resistance make the foam suitable for many outdoor and damp environments, as it resists water uptake. However, long-term exposure to sunlight and weathering may affect appearance and performance, so additional protection or enclosure is recommended for permanent external installations.

How do I choose the right thickness for my application?

Thinner sheets (such as 2mm to 4mm) are ideal for lightweight liners, gaskets and fine detailing, while thicker options (5mm, 6mm and above) provide increased cushioning, rigidity and insulation. Consider the level of impact protection, support and flexibility required, and select the thickness that balances performance with overall weight and space constraints.
