Even if you haven’t had much exposure to foam products, Polyethylene closed-cell foam is one of those products that you’ll recognise if you see it. It’s relatively rigid to the touch, and we sell it with or without self-adhesive backing.

You can find this material at the gym, home, work, and even at construction sites. Let’s take a look at what you need to know about one of the most versatile foams - polyethylene closed-cell foam.

What is polyethylene closed-cell foam used for?

Ideal for use in both commercial and personal projects, it’s a product you will see almost everywhere you look, without realising what it is. It’s great for arts and crafts, personal comfort, orthopaedic aids, yoga mats and more.

Polyethylene is a foam well suited for use as packaging for musical instruments, thermal insulation, the shock-absorbent that you’d find in crash helmets and even masonry supplies. It’s not likely to be used in upholstery unless it’s been specially treated. This is because it’s typically not fire retardant and does not comply with UKFR – UK Fire Regulations. However, many foam manufacturers can make fire retardant polyethylene by adding something extra to it, and we can do this too. So if you’re looking for fire retardant polyethylene closed-cell foam, get in touch, and we can arrange it for you.

You may also have seen it in the form of yoga rollers and kneeling pads. Not only is it lightweight and flexible, but It’s wear and tear-resistant, so it is used in many different ways.

What does polyethylene closed-cell foam look like?

What makes polyethylene what it is, is the closed-cell structure. Tiny bubbles that are stuck to each other but closed off make up the structure. The result is a water-resistant material that’s rigid and is extra strong compared to the open-celled type of foam.

When it’s not in its foam form, polyethylene is used as trash bags, containers for milk and chemicals such as oil. It’s also possible to laminate polyethylene to make it stronger with more protection. An example of this would be in the form of a bodyboard used at the seaside.

What are the advantages of using polyethylene closed-cell foam?

Other advantages of polyethene foam include being resistant to petroleum products and solvents and being antimicrobial, so you won’t find bacteria, mildew, or mould growing on it. If you press it down, it will return to its original form. All these characteristics are what make it so versatile in application, and it’s also possible to customise with additives and make it fire retardant and anti-static.

The anti-static form of polyethylene is typically used for the transportation and packaging of delicate electronic instruments. The foam can disperse the electrostatic charges that may form when in contact with the components or during their movement.

You’ll generally find polyethylene in a sheet or plank form, and these can be easily cut to fit the needs for packaging and casing. In addition to providing security, they can be good shock absorbers for transporting and storing items.

Fortunately, closed-cell foam is very good at resisting moisture and providing thermal insulation, so it’s the perfect packaging material. You may also see polyethylene in very thin sheets used to wrap around pipes to insulate them against both heat loss and freezing.

You’ll have seen the pool noodle by the pool, and it’s probably one of the most recognisable forms of this foam. Quite often, bolsters are also made from this foam which is used to give extra comfort. The crash pads used by high jumpers, climbers and gymnastics are also made from polyethylene closed-cell foam. Another additive that can be used with polyethylene foam is that of dyes. You may recall seeing it in white, black, red, yellow, green or blue.

Polyethylene is one of the most versatile foam products available. It can be customised to suit your needs, and this makes its applications far broader.
