Noodle water toys are made from polyethylene and are very recognisable for most people. This can then be used for seals between foundations, sill plates in buildings, insulations for pipes or protective bags or pouches for placement between goods. Insulation is made by putting together thin sheets of material to manufacture rolls of polyethylene. The closed-cell formation of the foam also means it can resist moisture and is therefore significant as a thermal insulation material.Īnother appealing possibility with this foam is that when it’s in the form of sheeting, polyethylene can be cut and laminated together to fabricate thicker sections for use as personal floatation devices, furniture inserts, bespoke packaging and for anything that needs extra support. From the sheet form to the cylinder or used as tubing to encase another product, this tough foam is excellent as both a shock absorber and an insulator. The greater the density, the smaller the cells are or, the thicker the walls are, which means a more robust material.Ĭlosed-cell polyethylene is versatile in many different ways, and it can be made to a wide range of shapes and sizes. It’s also a foam that is available in various densities, depending on how it is to be used. These items require antistatic packaging to dissipate electrical charges that may build and damage components.īy applying additives in the formula, it’s possible to get a consistent build of the material, rather than using treatments to change the foam after its creation. For example, antistatic varieties of the foam can be made for handling, packaging and distribution of delicate electronics. The process of manufacturing polyethylene foam involves the heating of polymer compounds, at which point additives can be used to change its properties. It’s these features in addition to it being customisable that make it practical to use in so many different ways. The majority of the time polyethylene foam is a resilient material that can return to its form despite being compressed but still provide cushion and security where required. This foam is also resistant to chemicals such as petroleum and solvents, besides being an inhibitor of growth for microbes such as bacterial, mould and mildew. This formation means that it has water resistance, hence why it’s typically used for floatation devices. When it comes to its structure, polyethylene foam is created with closed-cells, this means that it’s a foam that has tiny bubbles that are each separate from each other. It’s playing it’s part in a sophisticated modern world even if we don’t see it in use. You may see it in use as a flotation device, for packaging, a shock absorber or sound insulation. It’s a foam that is probably used the most out of all foams, but typically it’s not recognised. What do you need to know about Closed Cell Polyethylene Foam?Īs you now know, polyethylene foam has a versatility that lends itself to being suitable for many different purposes. ![]() Medical components such as x-ray & mobility aids.Transport of static-sensitive electronics.Packaging for heavier items such as machinery, automotive parts etc.Personal protection and safety such as helmet lining.Impervious to mildew, mould, rot and bacteriaĪpplications of closed cell polyethylene foam.Attributes of closed cell polyethylene foam Polyethylene foam is typically less springy, more rigid, and is widely used for swimming buoyancy aids, the lining of sports helmets, gym mats or other products that offer support and protection. In addition to being resistant to liquids, it’s a shock absorber, can provide thermal insulation and can also be used to seal gaps. This means that it is slightly harder, firmer and tougher than open-cell foams. This foam is made up of closed cells which are closed off from each other. The possibilities for this product are endless! Whether for an industrial, professional or personal use, polyethylene foam can do many different jobs. It comes in a range of colours, formulations, densities, styles and shapes that can be used in many different ways. What is Closed cell Polyethylene Foam used for?Īs one of the most versatile foams in existence, polyethylene is exceedingly practical and covers a wide range of applications.
