![]() You already know that this foam is great for sleeping on, but you can also find it in – This means that it can freely mould to a unique shape when pressure is applied to it, making it the ideal product for comfort purposes. The result is a unique foam type which has a high viscosity. This gives the foam an open cellular structure which allows air to flow freely through it. For example, in the case of memory foam, gas is pumped through it during production. When mixed together, these two chemical compounds begin to rise and foam, similar to the way a baking cake would rise.ĭuring the manufacturing process, polyurethane foams can be altered in specific ways to create certain traits. Polyurethanes are created by reacting together diisocyanates and polyols. Like all PU foams, memory foam is primarily made up of polyurethane. That name would catch on much later when the material became available for commercial use. Slow spring back foam may well be an informative name, but it doesn’t have the same ring to it as memory foam does. The resulting product was aptly named “slow spring back foam”. ![]() As such, they contracted their Ames Research Center to develop a material to provide this. NASA required a means to improve the safety of its aircraft cushions for pilots and passengers. You may be surprised to learn that NASA developed memory foam back in 1966. Because of this, it is regarded as a low-resilience polyurethane material (LRPu). This means that it has a high level of viscosity (hence the name viscoelastic foam). It can be manipulated into various forms and slowly returns to its original shape once any applied pressure is eased. ![]() Memory foam is a polyurethane foam type, sometimes referred to as viscoelastic foam. This foam type is one of the most popular and effective materials for providing support and comfort, however, it also has an array of other uses as well as a surprising history. When we think of memory foam, most of us will tend to attribute it to mattresses. ![]()
