Foamrite's frequently asked questions

Which foam or rubber is most suitable for me?

Please see our Foam and Rubber Suitability Table to help you find the most suitable foam or rubber for your needs.

What do you mean by sheet foam?

As polyurethane and polyethylene foam is bought in large blocks, we are able to slice off a ‘sheet’ of material, similarly to cutting a slice from a loaf of bread. This allows us to supply our high quality, commercial standard material in varying thicknesses, ready to be used to our customer’s liking.

Do you supply waterproof foam?

Yes, we do. Polyethylene, or closed cell foam, is impermeable, “waterproof”, and weather resistant, making it suitable for outdoor use.

If you have already purchased polyurethane “open cell” foam, you can alteratively wrap the product in a UV/ozone resistant material such as PVC.

My foam has changed colour...

Polyurethane foam reacts with natural light and carbon monoxide, causing it to discolour usually to a yellow; hence its unsuitability for outdoor use, unless covered. However, the quality of the foam is not tarnished and is 100% safe to use. So if your foam has discoloured, you will have nothing to worry about.

Will my foam get softer?

All foam softens with use. Lower density foams tend to soften quicker over time.

Why does my foam smell?

Many types of foam will have a ‘new foam’ odour. Different foams will have different fragrances and intensities of smell. This smell is harmless and will usually take 6 – 9 weeks to fully dissipate.

How safe is foam?

Foam produced within the UK is specifically manufactured to comply with British Standard Institute Regulations; meaning that our foams will not contain chlorofluorocarbons (CFCs) or Polybrominated diphenyl ethers (PBDEs). If you have previously bought foam from overseas, it may not adhere to strict British standards.
