Our Polyurethane Foam Conversion Capabilities.

As an ISO 9001 certified polyurethane supplier and specialist in converting and distributing sponge and foam, AS Rubber & Plastics converts polyurethane foam to your exact requirement — supplied as rolls, sheets or finished cut parts.

Our conversion capabilities include die-cutting and CNC cutting for precise, repeatable parts, log cutting and slitting to narrow widths, and lamination onto foams, fabrics and films. A range of adhesive backings can be applied depending on the type of fixing required, and multi-layer constructions are available where a single foam grade isn't enough.

Polyurethane Foam FAQs.

What is Polyurethane Foam Used For?

Polyurethane foam is a widely used material known for its comfort, flexibility, and insulation properties. It's commonly found in seating, packaging, acoustic insulation, and thermal sealing.

Its structure makes it a practical choice across industries—from automotive interiors and construction to furniture and general industrial applications.

What is the Difference Between Polyurethane and Polyethylene Foam?

While both are popular types of foam, they differ. Polyurethane foam is softer and more flexible, which makes it ideal for cushioning and comfort-focused applications. Polyethylene foam, on the other hand, is firmer and offers excellent resistance to moisture and impact, making it a better fit for protective packaging or flotation devices. The decision depends on what you need the material to do.

Which is Better: Polystyrene or Polyurethane?

The best choice depends on the specific application requirements. Polyurethane foam offers better insulation performance and higher strength, which makes it a good option for refrigeration, construction, and insulation panels. Polystyrene is more lightweight and cost-effective, often used in basic packaging or lightweight insulation. Polyurethane tends to be the go-to for applications where long-term durability and insulation performance are important.

Is Polyurethane Foam a Closed-Cell?

It can be either. Polyurethane foam is available in both open-cell and closed-cell formats. Open-cell foam is softer and ideal for sound absorption and cushioning, while closed-cell foam is denser and resists water, offering better thermal insulation and structural strength.

The right choice depends on the specific demands of your project. You can read more about the differences between open-cell and closed-cell foams here.

How Long Does Polyurethane Foam Last?

The lifespan of polyurethane foam varies depending on how and where it's used. In general, it can last 10 to 20 years or more when kept away from direct sunlight and extreme conditions. It holds up well under regular use, maintaining its shape and effectiveness over time.

We supply durable polyurethane foam products that maintain their shape and function over time. The material can be converted into finished items such as mats or packaging, or supplied cut to size in a range of colours, densities, and thicknesses.
