As a specialist foam rubber supplier, in addition to providing a wide range of foam rubber sheet materials, we also manufacture an extensive range of foam rubber products, including gaskets, washers, mouldings, extrusions and fabrications to suit applications within a wide range of industries. 

Let’s discuss the definition of foam rubber, its key advantages, and the range of foam materials CB Frost can supply.

What is Foam Rubber?

Rather than referring to a single material, foam rubber is a term given to any synthetic rubber material that has been manufactured to feature an air pocket filled cellular structure. Gas bubbles are introduced into liquid rubber materials via a foam agent. The liquid material is then cured to create solid foam material, ready for cutting and converting into a wide range of products. 

Rubber foam was first produced in 1929 by Dunlop and has been used commercially in many industries since the 1940s.

The Advantages of Foam Rubber Products

So why use foam polymers? Essentially, both closed cell and open cell foam materials feature a number of useful protective qualities and are used in products and services that we come across every day.

Shock absorption and vibration isolation

Foam materials feature an excellent ability to absorb and cushion the force of impact. As a result they come in useful in many sectors. For example, foam rubbers to absorb shock and impact for machines, protecting them from wear. Foams are also used to protect people, providing cushioning in vehicles. Foam rubber is even used as an underlay for carpets and flooring to allow for more bounce, leaving the surface feeling more comfortable underfoot!

Waterproofing and chemical resistance

Closed cell foam materials are waterproof and moisture resistant, so they are suited well to applications where the prevention of moisture ingress is important. Foams are also resistant to resting chemicals and oils.

Heat resistance and thermal insulation

Foam rubbers are widely used as a thermal insulation material within a number of different industries, including construction, packaging, HVAC systems, automotive and rail vehicles. As well as being flame and smoke resistant, and withstanding extreme temperatures, foam insulation materials are highly effective in regulating temperature.

Noise Insulation

As well as regulating heat, foam insulation also acts as an effective soundproofing material, helping to block out outside noises for buildings and vehicles.

Ease of conversion

Not only do rubber foam materials boast a range of advantageous characteristics, they can be converted into the required shapes for many applications via a range of manufacturing methods, including:

  • Cutting into Sheet material
  • Cutting into Strip/tape
  • Cutting into Gaskets and washers
  • Extrusion
  • Moulding
  • Fabrication
