Foam sheet is a wonderful polymer and available in many designs, shapes and sizes. There are quite a few verities of this product, each suitable for different application like packaging, art and craft and manufacturing of cushions and mattresses.
Different kinds of sheet foams have different characteristics that make them valuable for varied industries. The most common uses of different forms of foam include insulation, sound absorption, packaging and shape retention.
One common characteristic of all foam sheets is that they are all good insulators. Though they are not as voluminous as fiberglass and occupy less space than the latter, they offer better insulation. Of the many varieties, polyurethane sheets make the best insulators. However, they are quite expensive when compared to the other two main varieties of foam, namely Convoluted and Styrofoam.
Like any other foam sheet, convoluted foam is very helpful for packaging applications. Because of its anti-static properties, it’s frequently used for packing of electronic items like computers and other electronic devices using high technology. Additionally, this kind of foam also known as memory foam is widely used for making cushions for sofas and recliners. It’s called memory foam because of its ability to retain or remember the body shape of the user. Simply put, it means that after a while this foam automatically takes the exact posture of its occupier, making it remarkably relaxing and comfortable. Because of this characteristic, it is widely used for mattresses and cushions used in hospitals as it helps preventing bed sores and ulcers.
Another very useful feature of memory foam is its capacity to absorb noise. If you closely observe this foam you’ll see it has tiny conical structures like that of a cardboard egg tray. This kind of design is useful in fitting closely and absorbing sound waves that hit it directly. So, if noise reduction is an issue, you can apply a layer of this foam on the walls of your room.
As already pointed out, this kind of foam too has excellent insulation characteristics. Despite their being excellent insulators, each variety of foam has its own limitations, meaning that insulation may fail under certain conditions. Compared to other varieties, Styrofoam sheets come with minimum limitations, and therefore provide the best possible insulation. Nevertheless, this variety of foam is most widely used in packaging industry.
Styrofoam sheets with varying composition are being tried frequently. Different composition imparts it different characteristics, making it useful for specific applications. Styrofoam sheets are vastly used in art and craft sector. Most craft projects necessarily require using these sheets.
As Styrofoam sheets have many useful properties and come handy for craft purposes, these can easily be reused for making some unconventional items that can be displayed in the house. If you happen to have too much of it, you may store its small pieces in a box and reuse it for packing other items.
