Standard Foams
Flexible polyurethane foam (FPF) is a polymer and a popular material used in a wide range of products because of its ability to cushion, compress and return to its original shape. It’s produced by a chemical reaction between polyols, isocyanates, and water, creating a cell structure.
These standard polyurethane foam types are also available in convoluted profiles commonly known as egg box foam.
Common Applications of FPF:
Fire retardant polyethylene foam is a lightweight, closed-cell material that is made from polyethylene and a flame retardant additive. This additive gives the foam the ability to burn more slowly and self-extinguish. Fire retardant polyethylene foam has many uses, including:
- Flame retardancy: Reduces the spread of flames
- Thermal and acoustic insulation: Provides good insulation
- Water repellent: Repels water and is buoyant
- Chemical resistance: Resistant to chemicals, solvents, grease, and fluids
Fire retardant foam is made by treating a base foam material, like polyethylene or polyurethane, with fire retardant additives. These additives are usually made from fire-resistant fibres, like fibreglass, and work by creating a protective layer of char or releasing gases when exposed to heat.
Polyurethane foam is widely used in mattresses, sofas, upholstery, and car seats due to its comfort, durability, and ability to maintain shape over time. Its flexible nature allows it to cushion and support while returning to its original form, ensuring long-lasting comfort for household and automotive furniture.
Polyurethane foam is used extensively in medical devices and support products, such as wheelchair cushions, prosthetic padding, and hospital mattresses. Its ability to provide both comfort and stability, while remaining hypoallergenic and easy to clean, makes it ideal for healthcare environments.
Polyurethane foam is a go-to material for packaging delicate or fragile items, ensuring protection during transit. Its ability to absorb shocks and vibrations helps prevent damage to sensitive equipment, electronics, and other breakable goods.
Open-cell polyurethane foam is used in soundproofing solutions, where its structure helps absorb and dampen sound waves. Commonly used in recording studios, office spaces, and automotive interiors, it’s an effective material for reducing unwanted noise and vibrations.
Reticulated polyurethane foam is engineered for liquid and air filtration, thanks to its open-cell structure that allows fluids and gases to pass through while trapping contaminants. It’s commonly found in water filters, air purifiers, and HVAC systems, where it provides an efficient and durable filtering solution.
FPF is versatile and can be manufactured into various shapes and firmness levels. Since it’s mostly air, it’s lightweight, which reduces emissions during transportation.
However, FPF has some limitations. It doesn’t handle extreme temperatures well, can be flammable, and may break down when exposed to solvents. The chemicals that create FPF, like isocyanates, can also be toxic.
Reticulated Foam
Reticulated polyurethane foam has a unique honeycomb-like structure, created by removing the cell walls from regular polyurethane foam. This process leaves behind a 3D network of open cells, giving it a net-like appearance.
Key Properties:
Fire retardant polyethylene foam is a lightweight, closed-cell material that is made from polyethylene and a flame retardant additive. This additive gives the foam the ability to burn more slowly and self-extinguish. Fire retardant polyethylene foam has many uses, including:
- Flame retardancy: Reduces the spread of flames
- Thermal and acoustic insulation: Provides good insulation
- Water repellent: Repels water and is buoyant
- Chemical resistance: Resistant to chemicals, solvents, grease, and fluids
Fire retardant foam is made by treating a base foam material, like polyethylene or polyurethane, with fire retardant additives. These additives are usually made from fire-resistant fibres, like fibreglass, and work by creating a protective layer of char or releasing gases when exposed to heat.
The open-cell structure of reticulated polyurethane foam allows for outstanding absorption and filtration capabilities. This highly porous nature makes it ideal for applications where airflow or liquid flow is essential, such as in air and water filters. Its ability to absorb and manage fluids also makes it useful for medical and cosmetic applications, where precise absorption is required.
Despite being lightweight, reticulated foam is remarkably strong, offering excellent structural integrity without adding significant weight. Its low density makes it perfect for applications where minimising weight is crucial, such as in aerospace and automotive components, while still providing durability and performance.
Reticulated polyurethane foam is incredibly versatile, with applications spanning various industries. It is used in filtration systems, soundproofing materials, cushioning for electronics, medical devices, and even cosmetics. This adaptability makes it a valuable material for sectors ranging from healthcare and automotive to packaging and consumer goods.
Reticulated foam is highly resistant to a wide range of elements and chemicals, including water, humidity, acids, alkalis, fuels, and oils. This resilience ensures the foam maintains its structural integrity and functionality in harsh environments, making it a preferred choice for industrial applications such as chemical processing, automotive systems, and marine equipment.
Reticulated foam is easily compressed, particularly with lower cell counts, making it suitable for use in environments where space-saving or compact storage is needed. Its ability to compress and rebound without losing its shape makes it a valuable material in packaging, cushioning, and sealing applications, where protection and adaptability are essential.
Reticulated foam is produced through chemical etching or quenching, which involves treating the foam in a caustic bath to create the open-cell structure.
Chipfoam (Reconstituted Foam)
Chipfoam, or reconstituted polyurethane foam, is an eco-friendly solution made from recycled foam scraps. These leftover foam pieces are shredded, compacted, and bonded, resulting in a multi-coloured, durable material.
Benefits of Chipfoam:
Fire retardant polyethylene foam is a lightweight, closed-cell material that is made from polyethylene and a flame retardant additive. This additive gives the foam the ability to burn more slowly and self-extinguish. Fire retardant polyethylene foam has many uses, including:
- Flame retardancy: Reduces the spread of flames
- Thermal and acoustic insulation: Provides good insulation
- Water repellent: Repels water and is buoyant
- Chemical resistance: Resistant to chemicals, solvents, grease, and fluids

Chipfoam is an environmentally responsible option, as it utilises recycled foam waste, reducing the need for new raw materials and minimising landfill waste. This makes it a sustainable choice for companies looking to lower their carbon footprint while still benefiting from high-performance foam solutions.
Known for its longevity, chipfoam offers excellent structural stability and resistance to wear and tear. Its durability makes it suitable for heavy-duty applications such as flooring, gym mats, and packaging, where long-lasting performance is essential.
Chipfoam’s dense structure provides excellent sound absorption, making it ideal for noise control in applications like fans, blowers, and HVAC systems. It effectively dampens sound, reducing noise pollution in industrial and commercial environments.
Despite its strength, chipfoam is lightweight and easy to handle, making it an ideal material for insulation and transport applications. Its lightness ensures easy installation while also reducing shipping costs and energy consumption during transport.
Chipfoam is safe for use in contact surfaces such as gym mats, playgrounds, and furniture, as it does not harbour allergens. Its hypoallergenic properties make it suitable for environments where hygiene and safety are paramount, such as in schools, gyms, and healthcare settings.
Chipfoam is widely used in protective packaging, cushioning for furniture, and noise control solutions.
